Exploring Remington Model 11 Engineering Guide

Historical and Technical Overview of the Remington Model 11 Engineering

The Model 11’s design philosophy emphasized modularity, allowing for interchangeable parts and adaptability across calibers. This approach not only reduced production costs but also facilitated customization for hunters, sport shooters, and military applications. Its mechanical components—such as the two-lug bolt, controlled-round feeding system, and precision-machined barrel—were engineered to minimize wear and maximize longevity, distinguishing it from contemporaries like the Mauser and Springfield rifles.

Origins and Design Philosophy

The rifle’s two-lug bolt (later upgraded to a three-lug system in the Model 11-48) ensured positive locking, while its controlled-round feeding mechanism reduced malfunctions—a critical advancement over earlier designs reliant on manual manipulation. The stock, crafted from select hardwood (walnut or beech) with synthetic laminates in later models, prioritized recoil absorption and shooter comfort.

Mechanical Components and Engineering Significance

"The Model 11’s action was designed to be both a hunter’s tool and a marksman’s platform, balancing simplicity with precision." — Remington Arms Engineering Manual, 1935

1. Bolt Action and Locking Mechanism
   The Model 11’s bolt features a two-lug design (early models) or three-lug system (post-1948), with lugs machined at 90° angles to the bolt face. This configuration:
   
2. Provides positive extraction of spent cases, even under fouling conditions.
3. Reduces bolt wear by distributing stress evenly across the receiver.
4. Enables high-pressure cartridge compatibility (e.g., .308 Winchester, .243 Winchester).
The extractors and ejectors are spring-loaded, ensuring reliable case removal regardless of ammunition type.
5. Barrel and Chambering
   Early Model 11 barrels were cold-hammer-forged from 4140 steel, a material chosen for its tensile strength and fatigue resistance. Key specifications:
   
6. Contour: Initially round-barreled, later models adopted tapered or improved contour profiles for better heat dissipation.
7. Twist Rate: Typically 1:10 to 1:12 for standard cartridges, optimized for bullet stability at high velocities.
8. Chambering: Early models supported .30-06 Springfield, .270 Winchester, and .300 H&H Magnum; later variants added .308 Winchester and .244 Remington.
The free-floating barrel design (achieved via precision-machined action) minimized vibration, enhancing accuracy.
9. Stock and Ergonomics
   The stock’s design evolved to address recoil management and shooter fatigue:
   
10. Early Models (1932–1948): Walnut or beech stocks with straight or slightly curved combs, featuring checkered panels for grip.
11. Post-1948 Models: Introduction of synthetic laminates (e.g., fiberglass-reinforced plastic) to reduce weight and moisture absorption.
12. Pistol Grip and Buttplate: The pistol grip was deep and ergonomic, while the buttplate included adjustable cheekpieces for custom fit.
The bedding system used glass-bedding techniques (later models), ensuring the barrel and action remained aligned under recoil.
13. Trigger Mechanism
    The Model 11’s trigger is a two-stage design with:
    
14. Pull Weight: Typically 3–4 lbs (1.4–1.8 kg), adjustable via trigger screws.
15. Overtravel: Minimal to reduce muzzle flip and improve follow-through.
16. Safety: Early models featured a crossbolt safety (later replaced by a transverse bolt in military variants).
The trigger’s sear engagement was optimized for reliable firing even with lubricated cartridges.

Specifications of Early Production Models (1932–1948)

   Bolt Action and Fire Control Systems in the Remington Model 11 Engineering

   The Remington Model 11, introduced in 1932, represents a pinnacle of bolt-action rifle engineering with a focus on reliability, precision, and ease of maintenance. Its bolt action, derived from the Mauser system with Remington’s proprietary refinements, incorporates a dual-lug locking mechanism, a robust extractor-ejector assembly, and an integrated fire control system designed for both military and sporting applications. The interaction between these components ensures consistent cycling, accurate chambering, and fail-safe operation under extreme conditions. This section dissects the internal mechanics of the bolt action, the interplay of safety mechanisms, and the procedural intricacies of disassembly, reassembly, and maintenance, while addressing common failures and their engineering mitigations through documented case studies and geometric analysis.
   

   Dual-Lug Locking Mechanism and Bolt Geometry

   The Remington Model 11 employs a dual-lug bolt head with a 70° locking angle, a design adapted from the Mauser system but optimized for the .30-06 Springfield and later calibers. The primary locking lugs are positioned at the rear of the bolt body, engaging into corresponding recesses in the receiver’s bolt face. This configuration distributes recoil forces evenly across the receiver’s metal, minimizing stress on the action’s critical interfaces.

   The bolt’s cam profile is a critical feature, governing the timing of lug engagement and extraction. During the forward stroke, the bolt handle’s upward motion drives the bolt body forward while the camming surface rotates the lugs into the locked position. The primary cam (located on the bolt body) interfaces with the secondary cam (on the bolt handle), ensuring synchronized rotation. Key stress points include:
   

2. The lug roots, where fatigue cracks often initiate due to cyclic loading.
3. The bolt handle pivot pin, subject to torsional stress during rapid cycling.
4. The bolt face, which experiences high contact pressure during chambering.

Diagram Description (Bolt Internal Geometry):
1. Front View of Bolt Head (Locking Lugs):


5. Two symmetrical lugs with tapered engagement surfaces (15° angle) to ensure positive seating.
6. Locking recess depth: 0.060" (1.52 mm) to accommodate the receiver’s lug seats.
7. Lug width: 0.500" (12.7 mm) at the base, tapering to 0.400" (10.16 mm) at the engagement face.

2. Side View of Bolt Cam Profile:


8. Primary cam lift: 0.030" (0.76 mm) over a 90° rotation arc.
9. Secondary cam (handle): 0.045" (1.14 mm) lift, aligned to prevent binding.
10. Critical angle for lug engagement: 30° from the fully open position, where the lugs begin to seat.

3. Bolt Face and Chamber Interface:


11. Extractor groove depth: 0.035" (0.89 mm) with a 15° draft angle to facilitate cartridge extraction.
12. Firing pin recess: Centered, with a 0.125" (3.18 mm) diameter to prevent interference with the primer.

Extractor and Ejector Systems

The extractor and ejector in the Model 11 are designed for high-reliability operation under varied environmental conditions. The extractor is a spring-loaded claw mounted on the bolt face, engaging the cartridge rim via a 0.010" (0.25 mm) clearance to prevent rim damage while ensuring positive grip. The ejector, a fixed pin in the magazine floorplate, works in tandem with the extractor to expel spent casings during the bolt’s rearward motion.

Key Components and Functionality:


13. Extractor Spring: A torsion spring (0.018" wire, 12 turns) applies 1.5–2.0 lb (6.7–8.9 N) of force to the claw, compensating for brass wear and corrosion.
14. Extractor Claw Geometry: The inner radius (0.187" / 4.75 mm) matches the cartridge rim profile, while the outer radius (0.250" / 6.35 mm) ensures clearance with the chamber.
15. Ejector Pin: A 0.125" (3.18 mm) diameter steel pin, positioned 0.060" (1.52 mm) behind the extractor claw to avoid interference during extraction.

Failure Modes and Mitigations:


16. Extractor Spring Fatigue: Prolonged use or excessive lubrication degradation can reduce spring tension, leading to rim damage or cartridge hang-ups. Remington addressed this in later models by increasing spring wire thickness to 0.020" (0.51 mm).
17. Ejector Pin Wear: Excessive clearance (>0.005" / 0.13 mm) between the ejector and magazine floorplate can cause inconsistent ejection trajectories. The original design used a press-fit ejector sleeve to maintain alignment.

Safety Mechanisms Integration with Bolt Action

The Model 11 incorporates three primary safety features that interface directly with the bolt action: the manual safety lever, trigger guard, and bolt catch. These systems are engineered to prevent accidental discharges while maintaining rapid cycling capability.

1. Manual Safety Lever:


18. Mechanism: A rotary lever mounted on the right side of the receiver, engaging a blocking lug that prevents the trigger from contacting the sear.
19. Integration with Bolt Action: The safety lever’s cam follower interfaces with the bolt’s rear lug, ensuring the safety cannot be engaged when the bolt is forward (loaded) unless the bolt is first pulled to the rear. This design prevents accidental disarming during chambering.
20. Critical Tolerance: The safety lug clearance must be 0.005–0.010" (0.13–0.25 mm) to avoid binding while allowing full rotation.

2. Trigger Guard and Bolt Catch:


21. Trigger Guard: A stamped steel shroud enclosing the trigger, designed to prevent snagging while maintaining trigger accessibility. The trigger spring (3.5 lb / 15.6 N pull) is housed within the guard, with a pivot pin that must align within 0.003" (0.08 mm) to prevent trigger creep.
22. Bolt Catch: A spring-loaded detent in the receiver’s right wall, engaging a notch in the bolt’s rear lug. The catch’s release force is 1.0–1.5 lb (4.4–6.7 N), calibrated to allow rapid bolt manipulation while preventing unintended bolt release during recoil.

Safety System Failures and Solutions:

Common failures in the safety mechanisms include:


Safety Lever Binding: Caused by corrosion or debris in the cam track, leading to partial engagement where the rifle remains fireable. Remington’s solution was to chrome-plate the cam surfaces in later revisions.

Trigger Guard Deformation: Excessive pressure on the trigger guard (e.g., during prone shooting) can misalign the trigger pivot, resulting in trigger pull inconsistencies. Reinforced guards with 0.060" (1.52 mm) thicker steel were introduced in military contracts.

Bolt Catch Fatigue: The detent spring can lose tension over time, causing the bolt to fail to latch in the open position. Replacement springs with higher tempered wire (A2 tool steel) were specified in service manuals.

Disassembly and Reassembly Procedure for Bolt Action

Proper disassembly and reassembly of the Remington Model 11 bolt action require adherence to critical tolerances and lubrication protocols to preserve functionality. Below is the step-by-step process, emphasizing high-wear and high-stress components.

Tools Required:


23. Punch set (0.125" and 0.187" diameters)
24. Bolt face cleaner (for extractor groove)
25. Torque wrench (for bolt handle screws)
26. High-flash-point lubricant (e.g., Rem-Oil or CLP)

Disassembly Steps:
1. Remove the Bolt Handle:


27. Insert the 0.125" punch into the bolt handle screw recess and tap lightly to break the Loctite 243 (or equivalent) threadlock.
28. Use a 10mm socket to unscrew the bolt handle (torque: 15–20 in-lb / 1.7–2.3 Nm



Material Science and Manufacturing of the Remington Model 11 Engineering

The Remington Model 11 Engineering, introduced in 1957, exemplifies the integration of mid-20th-century metallurgy and machining techniques to produce a durable, high-performance bolt-action rifle. Its construction reflects the engineering priorities of the era: balancing cost, weight, and ballistic performance while ensuring reliability under field conditions. The materials selected for the Model 11—primarily steel alloys for structural components and hardwood for the stock—were chosen for their availability, machinability, and resistance to wear. Manufacturing processes such as cold heading, drop forging, and precision machining were employed to achieve consistency in critical dimensions, while heat treatment protocols were refined to optimize hardness and toughness. Defects in original production, including barrel harmonics and stock warping, highlighted the trade-offs between material properties and manufacturing tolerances, prompting iterative improvements in quality control.


Material Composition of the Model 11

The Model 11’s structural integrity relies on a combination of steel grades tailored to specific components, each selected for its mechanical properties and cost-effectiveness.

Barrel Construction
The barrel of the Model 11 is typically fabricated from 4140 chromium-molybdenum steel, a medium-carbon alloy known for its strength, toughness, and resistance to fatigue. This grade undergoes cold drawing to achieve precise internal rifling and external dimensions, followed by heat treatment to a hardness of Rockwell C 28–32 to balance wear resistance and ductility. The use of 4140 steel reflects a compromise between affordability and performance, as higher-alloy steels (e.g., 4150 or 8620) were less common in mass-produced rifles of the era. The barrel’s contour and wall thickness were optimized to minimize harmonics, a recurring issue in early production models where improper machining or heat treatment could induce standing waves, leading to accuracy degradation.

Receiver and Action Components
The receiver and bolt assembly are machined from 4140 or 8620 steel, with the latter preferred for its superior hardenability and wear resistance in high-stress areas such as the bolt face and lugs. The receiver’s design incorporates drop-forged sections for the magazine well and action housing, reducing material waste while ensuring structural rigidity. Critical surfaces, such as the bolt raceway, are induction hardened to Rockwell C 50–55 to withstand repeated cycling without deformation. The use of these alloys, combined with nitriding (a surface hardening process), mitigates galling and fretting, common failure modes in bolt-action rifles subjected to prolonged use.

Stock Material and Design
The stock of the Model 11 is crafted from American black walnut, a dense hardwood prized for its dimensional stability, shock absorption, and aesthetic appeal. Walnut’s natural oil content provides inherent resistance to warping, though early production stocks occasionally exhibited seasoning cracks or glue-line failures due to inconsistent drying processes. The stock’s laminate construction—comprising multiple layers of wood glued under pressure—enhances durability while allowing for complex contours. The forearm and pistol grip are often reinforced with fiberglass or phenolic resins in later models, addressing issues of splintering and impact resistance observed in early walnut-only stocks.


Manufacturing Processes and Durability

The Model 11’s production leveraged advanced machining techniques of the 1950s, with each process contributing to the rifle’s longevity and functional precision.

Forging and Machining


29. Drop Forging: Used for the receiver and bolt components to achieve grain flow alignment, enhancing fatigue resistance. Forged parts are subsequently milled and broached to tight tolerances, critical for the bolt’s engagement with the receiver.
30. Cold Heading: Applied to the firing pin and extractor to minimize material waste and ensure consistency in critical dimensions.
31. Broaching: Employed for the chamber and bolt face to produce smooth, precise surfaces, reducing the risk of case head separation during firing.

Heat Treatment and Surface Finishing
The rifle’s components undergo controlled quenching and tempering to achieve the desired hardness without compromising toughness. For example:


32. Barrels: Quenched in oil and tempered to 400–500°F (204–260°C) to relieve internal stresses.
33. Bolt Faces: Induction hardened to Rockwell C 55 to resist erosion from case head contact.
Surface treatments include:

34. Bluing: A phosphate conversion coating applied via immersion in a hot alkaline solution, forming a protective iron oxide layer. This process enhances corrosion resistance while providing a durable, low-reflectance finish.
35. Phosphatizing: Used on internal components (e.g., magazine springs) to prevent seizing and improve lubrication retention.

Quality Control and Defect Mitigation
Early production models exhibited several defects, primarily attributable to material inconsistencies or machining errors:


36. Barrel Harmonics: Addressed by refining the rifling twist rate (1:12 for .308 Win, 1:10 for .243 Win) and implementing vibration-dampening coatings in later revisions.
37. Stock Warping: Mitigated through strict wood seasoning protocols (drying to 6–8% moisture content) and the introduction of synthetic composite reinforcements in post-1960 models.
38. Bolt Binding: Resolved by adjusting lug engagement angles and incorporating tolerance stacks in the receiver’s bolt raceway.

Comparative Material Analysis: Model 11 vs. Modern Bolt-Action Rifles

The following table contrasts the Model 11’s material composition with contemporary bolt-action rifles, highlighting advancements in metallurgy, composites, and manufacturing precision.

Manufacturing Tolerances	±0.002" for critical dimensions (e.g., bolt raceway)	±0.0005" or tighter via CNC and additive manufacturing	Improved interchangeability, reduced wear, and enhanced accuracy.

Key Observations:

The Model 11’s material selection reflects the engineering constraints of its era, prioritizing affordability and machinability over modern advancements in lightweight alloys and composites. While contemporary rifles benefit from cold hammer forging (reducing barrel harmonics) and polymer receivers (lowering weight by 30–40%), the Model 11’s steel construction remains robust for its intended applications, particularly in military and law enforcement roles where durability outweighs portability concerns.

Finish and Corrosion Resistance

The Model 11’s finish serves dual purposes: functional protection against corrosion and a

53. Recoil management is superior in the Model 11 across all calibers, with its two-piece stock design and adjustable cheekpiece mitigating muzzle flip more effectively than the Model 70’s fixed stock.

Influence of Barrel Contouring and Twist Rate on Precision

Barrel contouring and twist rate are critical factors in optimizing bullet stability and long-range accuracy. The Remington Model 11 Engineering offers multiple barrel profiles (e.g., Heavy, Medium, Target), each tailored to specific shooting disciplines.

Barrel Contouring:


54. Heavy Contour: Optimized for recoil control and energy retention, ideal for hunting. Example: .308 Win Heavy with a 1:10 twist stabilizes 150gr bullets to 800+ yards.
55. Medium Contour: Balances velocity and accuracy, suitable for varmint and medium-range target shooting. Example: .22-250 Medium with a 1:12 twist excels with 55-75gr bullets.
56. Target Contour: Designed for minimal bullet weight loss and maximum precision, often used in benchrest competitions. Example: .308 Win Target with a 1:10 twist paired with 165gr match bullets.

Twist Rate Considerations:

For optimal stability, the twist rate should match the bullet’s BC (Ballistic Coefficient) and length-to-diameter ratio (L/D). A general rule:


Lighter bullets (50-75gr): 1:12 to 1:14 twist.

Medium bullets (100-150gr): 1:10 to 1:11 twist.

Heavy bullets (165gr+): 1:9 to 1:10 twist.

Empirical Data on Twist Rate Impact:

Caliber	Bullet Weight (gr)	Twist Rate	Stability at 600 Yards	Group Size (600 Yds)

.22-250	75gr SP	1:10	Excellent	1.0 - 1.5 MOA
.308 Win	150gr SP	1:1

Customization and Modifications for Enhanced Engineering in the Remington Model 11

The Remington Model 11 represents a classic bolt-action platform renowned for its precision engineering and adaptability. While factory configurations excel in reliability, aftermarket modifications can refine performance, ergonomics, and versatility without compromising the rifle’s inherent accuracy. This section explores engineering-focused upgrades, stock modifications, optical integration, and caliber conversions, emphasizing technical precision and material compatibility to preserve the rifle’s structural integrity and ballistic efficiency.


Aftermarket Upgrades for Precision and Reliability

The Remington Model 11’s modular design allows for targeted improvements in critical components, particularly the trigger, bedding, and barrel systems. These upgrades address common limitations—such as trigger pull weight, recoil management, and barrel harmonics—while maintaining compatibility with the rifle’s action and stock.


Critical Engineering Principle:
Modifications must align with the rifle’s original tolerances to prevent stress concentration, which can lead to accuracy degradation or mechanical failure. For example, altering the bolt face geometry without reaming the chamber risks thread stripping or excessive bolt thrust.

Trigger System Enhancements
The Model 11’s factory trigger often requires refinement to achieve competitive pull weights (1.5–2.5 lbs for target use). Aftermarket trigger upgrades, such as those from Timney, HLA, or Jewel, incorporate precision-machined components and adjustable disconnector systems. Installation involves:
1. Disassembly: Remove the trigger group by unpinning the hammer and sear, then detaching the trigger bar assembly.
2. Compatibility Check: Verify the new trigger’s pin spacing and sear engagement angles match the Model 11’s action (e.g., Remington’s Type 2 trigger mechanism).
3. Installation: Replace the factory trigger with the upgraded unit, ensuring the disconnector aligns with the hammer’s reset path. Reassemble with thread-locking adhesive on critical pins to prevent loosening.
4. Break-In: Cycle the bolt 50–100 times to seat the trigger components and achieve consistent pull weights.

Bedding Techniques for Accuracy
Factory bedding in the Model 11 often relies on basic polymer or felt pads, which may not optimize barrel harmonics. Advanced bedding methods include:


57. Glass Bedding: Uses epoxy and fiberglass cloth to create a rigid, vibration-dampening interface between the action and stock. Ideal for varmint and long-range applications.
58. Leadscrew Bedding: Employs a threaded leadscrew to preload the action into the stock, reducing movement during recoil. Requires precise torque measurement (typically 10–15 in-lbs) to avoid overstressing the wood.
59. Composite Materials: Carbon fiber or Kevlar wraps around the action can reduce barrel whip without adding excessive weight.

Warning:
Over-torquing during bedding can crack the stock or warp the action. Use a torque wrench and follow manufacturer guidelines for epoxy cure times (e.g., 72 hours for full strength with two-part epoxies like Devcon 2-Ton).

Barrel Profile and Contouring
Stock barrels on the Model 11 often feature heavy contours to dissipate heat, but aftermarket profiles (e.g., Bryan Litz, BAT) optimize harmonics and recoil. Key considerations:

60. Profile Selection:
61. Varmint: Medium-heavy contour with a 1:12 twist for stability with lightweight bullets (e.g., 55gr VLD).
62. Big Game: Heavy bull barrel with a 1:10 twist to handle recoil and heavier projectiles (e.g., 180gr Nosler).
63. Mounting: Use a barrel nut with a proper crimp or threaded interface (e.g., BAT TA32) to prevent movement. Avoid welding or excessive torque on the barrel crown.
64. Free-Floating: Ensure the barrel does not contact the stock or forearm to eliminate harmonics. Use barrel jacks or synthetic stocks if necessary.

Stock Modifications for Ergonomics and Durability

The Model 11’s walnut or synthetic stock can be customized to improve grip, reduce fatigue, and enhance sling compatibility. Modifications must preserve the rifle’s balance and avoid compromising the action’s integrity.

Cutting Checks and Thumb Indentations
Factory stocks often lack ergonomic features for extended shooting sessions. Precision cuts can be made using a dovetail file or router:
1. Thumb Indent: Carve a shallow recess (3–5mm deep) on the rear of the stock’s comb to improve thumb placement during bolt manipulation. Avoid cutting into the action’s recoil lug area.
2. Forearm Checks: Add 45° angled cuts (1–2mm deep) to the forearm’s grip surface to prevent slippage. Use a rasp to smooth edges and apply grip tape (e.g., Hogue) for additional traction.
3. Magazine Well Modifications: For semi-auto conversions, ensure the magazine well aligns with the action’s feed ramp. For bolt actions, avoid altering the well’s depth to prevent bolt-face interference.


Material Note:
Walnut stocks should be pre-soaked in linseed oil for 24 hours before cutting to prevent splitting. Synthetic stocks (e.g., McMillan) may require heat-forming tools for permanent modifications.

Sling Swivel and Comb Reinforcement
The Model 11’s stock lacks factory sling swivels, necessitating aftermarket additions:
1. Swivel Installation:

65. Top Swivel: Use a 14.5mm swivel (standard for AR-style slings) mounted 10–12 inches from the muzzle. Secure with sheet metal screws and Loctite 243 to prevent loosening.
66. Bottom Swivel: Positioned 6–8 inches forward of the pistol grip for a low-profile carry. Use swivel studs with rubber grommets to reduce wear on the stock.
2. Comb Reinforcement: For rifles used with high-recoil cartridges (e.g., .30-06), reinforce the comb with a carbon fiber strip or fiberglass tape to prevent cracking. Apply with epoxy and clamp during cure.

Pistol Grip and Forearm Adjustments


67. Pistol Grip: Replace the factory grip with an adjustable cheekpiece (e.g., Hogue) or a custom-molded grip to improve cheek weld. Ensure the grip’s angle matches the shooter’s dominant eye position.
68. Forearm Length: For taller shooters, a spacer block (e.g., McMillan) can extend the forearm without altering the action’s position. For shorter shooters, a reduced-length forearm may be required, but ensure the barrel’s center of gravity remains balanced.

Optical Integration Without Compromising Balance

Mounting modern optics on the Model 11 requires careful planning to maintain the rifle’s center of gravity (CG) and recoil characteristics. The stock’s design and action placement dictate mounting solutions.

Scope Mounting Considerations
1. Mount Selection:


69. Low-Profile Mounts: Ideal for varmint rifles (e.g., Leupold M1, Vortex Ring). Use 1-inch tubes for lighter setups (e.g., Swart 2400).
70. High-Capacity Mounts: For heavy scopes (e.g., Nightforce NXS), use two-piece bases (e.g., Harris Bipod) to distribute weight.
2. CG Preservation:

71. Scope Placement: Mount the scope as close to the action as possible (typically 5–7 inches above the bore) to minimize cant. Use a scope level to ensure the rifle remains balanced when empty.
72. Counterweights: For long scopes (>30 inches), add a barrel weight (e.g., BAT B2) or stock weight (e.g., Hogue OTTW) to offset the front end.
3. Zeroing Process:

73. Use a bore sight to align the scope before mounting. After installation, shoot a 5-shot group at 100 yards and adjust the scope’s turrets to center the impact.

Red Dot Sight Integration
Red dots (e.g., Trijicon RMR, Vortex Sparc) require a Picatinny rail or Weaver-style mount on the rifle’s top rail. Steps:
1. Rail Installation:


74. For factory rails, use a removable base (e.g., Magpul MBUS) to avoid permanent modifications.
75. For custom setups, a M-LOK rail can be attached with rivets or screws (ensure no interference with the bolt lift path).
2. Mounting Height:

76. Position the red dot 1
