The 12JSDX240-1701105 Main Shaft / 2nd Shaft is a critical internal component of heavy-duty manual transmissions, specifically designed for FAST 12JSDX240 series gearboxes widely used in Shacman heavy trucks. This shaft plays a central role in torque transmission, gear engagement, and overall drivetrain stability.

As the primary rotating and load-bearing element inside the gearbox, the main shaft (or second shaft, depending on configuration) transmits engine torque to the gear sets while maintaining precise alignment under continuous load. Any deviation in material quality or machining accuracy can directly affect shifting smoothness, noise levels, and gearbox lifespan.

At xmllauto, this component is produced using high-grade alloy steel through forging, CNC machining, and controlled heat-treatment processes. Each shaft is engineered to meet OEM dimensional tolerances and mechanical performance requirements. Strict inspection procedures - including spline accuracy checks, hardness testing, and surface defect inspection - ensure consistent quality and reliable field performance.

This main shaft is suitable for gearbox overhaul, scheduled maintenance, and aftermarket replacement, helping fleet operators and service centers restore transmission efficiency while controlling long-term maintenance costs.

1.Compact and Integrated Design
