• Key functions

1.Power Transmission: Serves as the critical link between the engine and hydraulic pump, converting engine mechanical energy into rotational motion for the pump’s internal components. Without it, the pump cannot generate hydraulic pressure.

2.Component Alignment: Maintains precise centering of the cylinder block and pistons, ensuring smooth piston movement and consistent oil compression. Poor alignment (from a bent or worn shaft) leads to reduced pump efficiency and premature failure.

3.Seal Protection: The shaft’s smooth surface and proper diameter tolerance ensure a tight seal with the pump’s oil seals, preventing hydraulic oil leakage (a major cause of reduced system pressure and increased maintenance costs).

4.Torque Resistance: Handles peak torque loads during heavy operations (e.g., excavator boom lifting under maximum load), resisting bending or torsional deformation that would disrupt pump function.
