Hydraulic Pump 41/29 cc/r 16/14 GPM for JCB
Rotation Direction: Right-hand (clockwise)
Function and Fault Diagnostics
The hydraulic pump is the heart of the machine, converting the engine's mechanical power into hydraulic oil pressure. Failure of the pump immobilizes the entire machine. The most common causes of failure are contaminated oil or running “dry” (cavitation).
Signs of a failing hydraulic pump include:
⚠️ Safety Warning
Before disassembling the pump, ensure that all hydraulic pressure is fully released (e.g., lower attachments and move the joysticks with the engine off). Pressurized hydraulic oil can pierce the skin. Always secure the machine to prevent rolling or tipping.
