Essential FAW 50040551063C00E Cab Hydraulic Lock Assembly

Ensure safe and stable cab tilting operations on your FAW truck with the genuine Cab Hydraulic Lock Assembly, OEM part number 50040551063C00E. This critical safety mechanism acts as a secondary locking system that securely holds the cab in the raised position during engine and transmission maintenance. As a vital component within the category of reliable and safety-focused Faw truck parts, the 50040551063C00E provides essential protection for technicians working underneath.

It prevents accidental cab lowering caused by hydraulic system failure or inadvertent control lever activation. Replacing a worn or faulty lock assembly with the genuine 50040551063C00E restores this crucial safety feature, ensuring compliance with workshop safety standards and providing peace of mind during every servicing procedure. This direct-fit, heavy-duty assembly is engineered for durability and reliable engagement under the weight of the cab.

Critical Safety Function of 50040551063C00E

The primary purpose of the Cab Hydraulic Lock Assembly 50040551063C00E is to provide a fail-safe mechanical lock. When the cab is tilted using the hydraulic pump, this assembly automatically or manually engages to physically prevent the cab from lowering. It acts independently of the hydraulic system, serving as a backup in case of hose rupture, seal failure, or pump malfunction.

This is a non-negotiable safety feature that protects maintenance personnel from catastrophic injury. The 50040551063C00E ensures that even if all hydraulic pressure is lost, the multi-ton cab remains securely propped in the upright position, allowing safe access to the engine compartment.

Integration with Cab Tilt System

The 50040551063C00E assembly works in tandem with the main cab tilt hydraulic cylinders and pump. It is typically mounted on the cab’s subframe or pivot points. When the cab reaches its fully tilted position, a latch, pin, or hook mechanism within the 50040551063C00E engages with a corresponding striker or bracket on the chassis.

This engagement is often audible or felt by the operator, providing positive confirmation that the lock is secured. To lower the cab, a separate release lever or cable connected to the 50040551063C00E must be activated, disengaging the mechanical lock before the hydraulic system can be operated.

Robust Construction for Maximum Safety

The 50040551063C00E is built from high-tensile strength steel components, often forged or cast for exceptional durability. The locking pawl, pin, or hook is heat-treated to resist deformation under the immense load of the cab. All pivot points feature hardened steel bushings or bearings to ensure smooth operation and prevent seizing from corrosion.

Springs within the assembly are designed for consistent tension over thousands of cycles. The entire 50040551063C00E unit is coated with anti-corrosion treatments to withstand exposure to road spray and weather, ensuring reliable function throughout the truck’s service life.

Installation and Calibration Process

Installing the 50040551063C00E requires the cab to be securely supported. The old lock assembly is disconnected from its mounting points and any release cables. The new genuine 50040551063C00E assembly is then positioned, ensuring all mounting bolts are aligned and torqued to specification.

Critical alignment follows: the locking mechanism must be adjusted so it engages fully and positively with the chassis striker when the cab is fully tilted. The release cable must also be adjusted for correct tension, allowing easy disengagement from a safe standing position. Final testing with the hydraulic system is mandatory.

Signs of Wear or Failure to Monitor

Difficulty engaging or hearing a weak “click” when the cab tilts indicates a misaligned or worn lock mechanism. A lock that does not hold securely, allowing the cab to settle or shake, is a critical failure. A seized or stiff release cable that prevents easy disengagement is a hazard.

Visible corrosion, cracks, or bends in the components of the 50040551063C00E assembly compromise its strength. Any of these symptoms mean the lock is unreliable and the entire 50040551063C00E assembly should be replaced immediately before further cab tilts are attempted.

Model-Specific Design and Fitment

The 50040551063C00E is engineered for specific FAW truck models with tilt cabs. Its design, mounting points, and engagement geometry are calculated based on the cab’s weight, center of gravity, and tilt arc. Using the correct OEM part is essential for proper function.

An incorrect or universal lock may not align, may engage only partially, or may not be rated for the specific load, creating a false sense of security. The genuine 50040551063C00E guarantees the lock is integrated correctly with your truck’s design.

Redundant Safety and Peace of Mind

The hydraulic lock provides redundancy, a core engineering principle for critical safety systems. It ensures that even if the primary system (hydraulics) fails, a secondary system (mechanical lock) is there to prevent an accident. This redundancy is why the 50040551063C00E is non-negotiable.

For fleet managers and owner-operators, this translates to direct protection of their most valuable asset: their personnel. It also protects against costly damage to the cab, engine, and chassis that could occur from an uncontrolled cab drop.

Routine Maintenance and Inspection Schedule

Inspect the 50040551063C00E assembly every time the cab is tilted. Visually check for damage, corrosion, or loose fasteners. Listen for a positive, audible engagement “clunk.” Test the release mechanism to ensure it operates smoothly from the designated safe position.

Lubricate all pivot points and the release cable periodically with a recommended lubricant to prevent sticking and corrosion. This simple maintenance ensures the 50040551063C00E functions reliably when needed most.

Why Genuine FAW Part 50040551063C00E is Essential

With a safety-critical component, there is no room for compromise. The genuine 50040551063C00E is manufactured to FAW’s precise specifications for material strength, hardness, and dimensional accuracy. It undergoes rigorous testing to ensure it can withstand the dynamic loads and shocks involved in truck operation.

Aftermarket locks may use inferior metals or imprecise casting, risking catastrophic failure under load. The genuine part guarantees the lock will perform as designed in an emergency, making it the only responsible choice for replacement.

Operational Workflow with a Functional Lock

A proper workflow with the 50040551063C00E involves tilting the cab using the hydraulic pump until a distinct engagement sound is heard. The operator should then visually confirm the lock is engaged before proceeding underneath. To lower, they must first pull the release cable or lever, then carefully operate the hydraulic control.

This disciplined process, enabled by a reliable lock, prevents “bypassing” safety procedures. Training all personnel on this procedure and the importance of the 50040551063C00E is as important as maintaining the part itself.

Integration with Other Cab Tilt Components

The 50040551063C00E is part of a system. It works with the hydraulic pump, cylinders, tilt hinges, and cab latches. When replacing the lock assembly, inspect the condition of the striker plate on the chassis for wear or damage, as this affects engagement.

Also, check the hydraulic system for leaks and the cab’s primary latches for secure closure. A holistic approach to cab tilt system maintenance ensures all components, including the safety lock, function together seamlessly and safely.

Cost of Neglect vs. Value of Safety

The cost of a new 50040551063C00E assembly is insignificant compared to the potential consequences of its failure. A single accident involving an unlocked cab can result in severe injury, loss of life, massive liability claims, and devastating damage to the vehicle.

It also leads to operational downtime and reputational harm. Investing in and maintaining this safety device is the ultimate expression of valuing human life and responsible asset management. It is not an expense but a fundamental insurance policy.

Conclusion: The Non-Negotiable Safety Component
