FAW J6P Gearshift Mechanism: Deconstructing 58 Critical Parts for Flawless Driver Control

Welcome to this comprehensive deconstruction of the FAW J6P Gearshift Mechanism for the CA10TA160M 10-speed transmission. This guide, for the FAW Jiefang CA3250P66K2L1T1E 6×4 dump truck, breaks down the 58 components that form the complete “Human-Machine Interface,” from the driver’s hand to the gearbox’s shift forks.

The FAW J6P Gearshift Mechanism is a complex, multi-point assembly. Its logic is to translate the driver’s “H-pattern” motion into precise, isolated fore-aft and side-to-side movements at the gearbox. It is a system of levers, brackets, and cushions designed to provide precise, low-effort shifting while isolating the cab from engine vibration.

Core 1: The “Driver Interface” Logic (The Shifter)

This group represents the part of the FAW J6P Gearshift Mechanism that the driver physically interacts with inside the cab. Its logic is to translate hand movements into two distinct “X” and “Y” axes of motion.

1. Component: ‘Gearshift handle & gear knob plate assy’ (1703025B91W-C00)
This (Comp 1) is the main “shifter” itself. This assembly includes the gear lever and the knob (which contains the Hi/Lo range selector switch). This is the primary input point for the entire FAW J6P Gearshift Mechanism.

2. The “Pivot” Group (Comp 3, 4, 6, 9)
This group includes: ‘Gearshift lever’ (Comp 3), ‘Ball joint housing – gearshift shaft’ (Comp 4), ‘Bushing – gearshift lever ball joint’ (Comp 6), and ‘Ball joint pin – gearshift shaft’ (Comp 9).

The Ball Joint Logic is how the “H-pattern” works. The ‘Ball joint housing’ (Comp 4) and ‘Bushing’ (Comp 6) create a “socket” that bolts to the cab floor. The ‘Lever’ (Comp 3) sits in this socket, with the ‘Ball joint pin’ (Comp 9) acting as the pivot.

This FAW J6P Gearshift Mechanism pivot allows two types of motion: 1) Side-to-side (the “Select” motion), which pivots the entire lever. 2) Fore-aft (the “Shift” motion), which also pivots on this ball. This assembly separates these two distinct movements and transmits them to the linkages below.

3. The “Support & Boot” Group (Comp 5, 7, 10, 14, 17, 18)
This group includes: ‘Rear joint – gearshift lever ball joint’ (Comp 5), ‘Dust cover – gearshift lever’ (Comp 7), ‘Upper support – gearshift lever’ (Comp 10), ‘Lower dust cover’ (Comp 14, 17), and ‘Lower dust cover spring’ (Comp 18).

The Sealing Logic is the job of the multiple ‘Dust covers’. These flexible rubber boots (Comp 7, 14, 17) completely seal the pivot mechanism, preventing cab noise, fumes, and dirt from entering, while keeping the pivot grease in. The ‘Rear joint’ (Comp 5) and ‘Upper support’ (Comp 10) form the structural bracket that holds the entire L-shaped lever assembly of the FAW J6P Gearshift Mechanism.

Core 2: The “Chassis Linkage” Logic (Motion Transfer)

This group represents the long, external rods and brackets of the FAW J6P Gearshift Mechanism. Its logic is to transfer the “Select” and “Shift” motions from the cab floor to the gearbox, while isolating the cab from vibration.

1. Component: ‘Longitudinal tie-rod assy – gearshift’ (1703095-14B)
This (Comp 36) is the main “shift” rod. This is the long, rigid rod that connects to the shifter’s fore-aft linkage. When the driver pushes the lever forward, this rod is “pushed” backward, transferring the “shift” motion along the chassis to the gearbox.

2. The “Support” Group (Comp 25, 26, 30, 43, 51)
A long rod like Comp 36 cannot “float.” This group provides its support. It includes: ‘Lower support assy’ (Comp 25), ‘Support bracket’ (Comp 26), ‘Block – shift lever support’ (Comp 30), ‘Fixed bracket & joint assy’ (Comp 43), and ‘Fixed bracket support assy’ (Comp 51).

The Rigidity Logic is their function. These heavy-duty brackets bolt to the truck’s chassis frame. They hold the rods and shafts of the FAW J6P Gearshift Mechanism in perfect alignment, allowing them to slide and rotate smoothly without flexing or binding.

3. The “Vibration Damping” Group (Comp 31, 32, 44, 45, 46, 47)
This group includes: ‘Shaft – gearshift lever’ (Comp 31), ‘Soft bushing’ (Comp 32), ‘Pipe sleeve – shift lever upper bracket’ (Comp 44), ‘Cushion base’ (Comp 45), ‘Soft cushion’ (Comp 46), and ‘Gasket – shift lever bracket’ (Comp 47).

The Isolation Logic is critical for driver comfort. The engine and gearbox vibrate violently, while the cab (where the driver sits) is on its own air-ride suspension. This part of the FAW J6P Gearshift Mechanism uses ‘Soft cushions’ (Comp 46) and ‘Soft bushings’ (Comp 32) to absorb these vibrations. This ensures that the shift lever in the cab does not “buzz” or “shake,” providing a smooth, high-quality feel for the driver.

Core 3: The “Pneumatic Assist” Logic (The Air System)

This group contains the air “plumbing” for the FAW J6P Gearshift Mechanism. Its logic is to route compressed air to the various pneumatic systems that make shifting a 10-speed gearbox easy (the booster and the PTO).

1. Component: ‘Booster inlet air pipe assy’ (1703670A369)
This (Comp 57) is the main air supply line for the “shift booster.” The FAW J6P Gearshift Mechanism is “air-assisted” to reduce the physical effort needed to move the internal shift forks. This pipe delivers the high-pressure air that powers this booster.

2. Component: ‘PTO inlet air pipe assy’ (1703660A369)
This (Comp 56) is the air supply line for the Power Take-Off. The PTO (which runs the dump body’s hydraulic pump) is also engaged using compressed air. This pipe routes air from the driver’s PTO switch to the PTO’s own air cylinder.

3. Component: ‘Solenoid valve inlet pipe assy’ (1703620A83A)
This (Comp 54) is the “signal” pipe. This FAW J6P Gearshift Mechanism component likely carries the low-pressure “pilot” signal from the driver’s Hi/Lo range switch to the ‘Follower valve’ (solenoid valve) on the side of the gearbox.

4. The “Connectors” Group (Comp 55, 58)
This group includes: ‘Pipe joint – tee’ (Comp 55) and ‘Pipe joint – taper adapter’ (Comp 58). These are the critical “connectors” that allow the air lines to “Tee” off from the main air supply or “adapt” to different thread sizes on the valves and cylinders. They are a core part of the FAW J6P Gearshift Mechanism‘s air logic.

Core 4: The “Sealing & Floor” Logic (The Boots)

This group represents the final “sealing” layer of the FAW J6P Gearshift Mechanism, where the linkage physically passes through the cab’s floor.

1. Component: ‘Seal cover assy – driving cab floor’ (1703030-61B)
This (Comp 50) is the main “boot” assembly. This is a large, flexible rubber boot or “gaiter” that is mounted on the cab floor. The FAW J6P Gearshift Mechanism linkage (Comp 36, etc.) passes *through* it.

Its Sealing Logic is to provide a perfect, flexible seal. It must accommodate the “Shift” and “Select” movements of the linkage while completely blocking cab noise, road heat, water, and fumes from entering the driver’s compartment. It is held in place by ‘Self-tapping screws’ (Comp 49).

2. Component: ‘Seal boot base – lock’ (1703036A70A)
This (Comp 48) is the “base” or “retainer ring” for the boot. This component bolts to the floor and provides the rigid “frame” that the flexible rubber ‘Seal cover’ (Comp 50) clamps onto, ensuring a tight, durable seal for the FAW J6P Gearshift Mechanism.

3. Component: ‘Hoses’ (Comp 33, 34)
These include: ‘Outer hose – front joint’ (Comp 34) and ‘Pipe sleeve – front joint’ (Comp 33). These are protective “sleeves” or “hoses” that cover the linkage rods themselves, providing another layer of protection for the FAW J6P Gearshift Mechanism against dirt and corrosion.
