Product Model:

8-94435-160-1 Isuzu 4JA1 D-MAX, TFR54

Product Details:

1. Precision Transmission Design: The shaft end features a "bell-shaped" structure to fit the clutch driven plate, with a coaxiality tolerance of ≤0.02mm; the input gear is designed with helical teeth, ensuring high meshing overlap, transmission noise ≤62dB, and power transmission loss <3%.

2. High-Strength Integrated Structure: The shaft body and input gear are integrally forged and treated with carburizing and quenching, resulting in a tooth surface hardness of 60~62HRC. It can withstand the maximum torque input from the engine (up to 290N·m for the 4JA1 engine), preventing shaft-gear separation or fracture.

3. Core Component for Transmission Power Input: As the connecting component between the transmission and the engine, it connects to the clutch through the "bell-shaped" structure, transmitting engine power to the inside of the transmission (the input gear meshes with the intermediate shaft gear), serving as the "first transmission node" in the power flow.

4. Commercial Vehicle Transmission Part: Suitable for Isuzu 4JA1 series commercial vehicles/pickup trucks, meeting the high-load power transmission requirements of these models in freight transport, engineering operations, and other scenarios. It is one of the core wear parts of the transmission for these models. Used in the overhaul of Isuzu D-MAX/TFR54 transmissions to replace worn/damaged input shafts (such as worn gear teeth, deformed shaft ends), restoring the transmission's power input function.
