Compatible Excavator Models
The 708-1T-00520 hydraulic pump is designed for compatible applications including:
PC35MR-2 • PC40MR-2 • PC50MR-2
Exact fitment may vary according to machine serial number and hydraulic system configuration. We recommend confirming the original pump part number, machine model, serial number, drive shaft, mounting dimensions and hydraulic port configuration before ordering.
Hydraulic Main Pump Function
The hydraulic main pump is one of the most important components in an excavator. Driven by the engine, it draws hydraulic oil from the tank and delivers pressurized oil to the machine's hydraulic control system.
The hydraulic power generated by the pump supports major machine functions including:
Boom Operation • Arm Operation • Bucket Control • Swing Movement • Travel System • Auxiliary Hydraulic Functions
A correctly operating pump is essential for maintaining smooth, responsive and efficient excavator performance.
Main Pump Structure
The JISION 708-1T-00520 Main Pump Assy is designed around critical components required for reliable hydraulic operation, including:
Drive Shaft • Pump Housing • Hydraulic Control Components • Bearings • Internal Rotating Components • Oil Ports • Sealing Components • Mounting Flange
Precision manufacturing and proper assembly help maintain stable hydraulic pressure and flow under normal operating conditions.
Common Replacement Situations
Hydraulic pump replacement may be considered when professional diagnosis identifies problems such as:
- Weak or slow hydraulic functions
- Reduced boom, arm or bucket performance
- Abnormal hydraulic pump noise
- Excessive pump vibration
- Unstable hydraulic pressure
- Hydraulic oil leakage from the pump
- Excessive internal wear
- Poor machine response under load
Because similar symptoms can also be caused by control valves, hydraulic cylinders, relief valves, filters, hydraulic oil or other system components, proper hydraulic diagnosis is recommended before replacing the pump.
