AZ2203220126 1st & 2nd Gear Fork Shaft Assembly

AZ2203220126 is a dedicated 1st/2nd gear shift fork shaft assembly for heavy-duty gearboxes and serves as a core component of the shifting mechanism. It mainly controls the engagement and disengagement of the 1st and 2nd gear synchronizers to ensure smooth and reliable gear shifting.
The assembly is integrally formed and machined with standard specifications for positioning grooves and mounting points, featuring uniform and moderate assembly clearance.
It balances structural strength and mechanical toughness, avoiding common faults such as wear, looseness and gear position deviation during long-term driving.
Compatible with corresponding heavy-duty truck gearbox models, it can directly replace damaged original parts with high fitting accuracy, stable operation and long service life.
AZ2203220126 1st/2nd gear shift fork shaft assembly is forged from high-quality alloy steel with dense texture and high toughness. It features excellent bending and compression resistance, and is not prone to deformation or fracture.
Treated by professional quenching and tempering heat treatment process, it achieves high surface hardness, outstanding wear resistance and impact resistance, adapting well to frequent gear shifting conditions of heavy-duty vehicles.
The shaft body is precisely turned and ground with high coaxiality and reasonable sliding clearance. It ensures smooth and sensitive shifting between 1st and 2nd gears without jamming or abnormal noise, and effectively prevents gear jumping and slipping.
Compliant with original factory process standards, it has precise dimensions and good interchangeability. It is easy to install without modification, making it a high-quality replacement part for gearbox maintenance.
