The 708-25-04071 cylinder block, pistons and piston shoes are machined to HPV132 OEM clearance, restoring volumetric efficiency and cutting the internal bypass that drives oil temperature up on the PC710-5.
Barrel face and valve plate are surface-matched to Ra 0.2 during assembly, eliminating the break-in leakage phase that reduces new-pump efficiency on the PC710-5 HPV132 circuit.
The HPV132 regulator is pre-set to the PC710-5 engine power curve, preventing engine overload during combined boom, swing and travel demand without field adjustment.
708-25-04071 port configuration, flange bolt circle and spline engagement are confirmed for the PC710-5, providing direct bolt-on installation without adaptor blocks or hose rerouting.
FAQ
Q: What symptoms indicate the 708-25-04071 pump needs replacing on a PC710-5?
A: Main circuit pressure falls below specification on a gauge test, all functions slow simultaneously at rated engine speed, HPV132 case-drain flow exceeds the OEM limit, oil temperature rises faster than normal, and metal particles appear in the hydraulic oil.
Q: Should I replace the valve plate when fitting the new 708-25-04071 pump?
A: This 708-25-04071 assembly includes a new matched valve plate and rotating group, so the sealing interface is correct from installation. No additional valve plate replacement is required.
Q: Does the 708-25-04071 pump fit other Komatsu models besides the PC710-5?
A: Cross-reference numbers 708-25-04071 / 708-25-04090 / 708-25-04081 / 708-25-04080 / 708-17-01040 apply. The 708-25-04071 pump is dimensionally matched to the HPV132 pump application; confirm your machine serial number with our team if you are unsure of compatibility.
Q: How to confirm the 708-25-04071 is the correct pump for my PC710-5?
A: Match the pump model plate reading 708-25-04071 and confirm the machine model is PC710-5. Provide the pump and machine serial numbers to our team for exact cross-reference confirmation.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
