Bulldozer Komatsu D475A-5 Hydraulic Pump Main Pump Piston Pump 708-2G-00060 708-2G-01060

High-performance hydraulic main pump designed specifically for Komatsu D475A-5 bulldozers, compatible with part numbers 708-2G-00060 and 708-2G-01060.

• Abnormal pump noise: Worn pistons and slippers, scratched valve plate; air ingress in suction line, contaminated hydraulic oil.
• Insufficient output pressure: Internal leakage caused by worn piston pairs and aged seals; faulty pressure regulator, pressure cannot reach rated value.
• Slow machine movement: Reduced volumetric efficiency of hydraulic pump and insufficient flow; clogged suction filter element, excessive suction resistance.
• Excessively high hydraulic oil temperature: Heavy internal leakage inside pump and increased frictional heat; improper hydraulic oil grade or deteriorated oil.
• Pump housing leakage: Aged and damaged end cover seals and O-rings; uneven tightening torque of bolts, cracked housing.

• Verify the stamped part number on old pump and bulldozer model before order placement. Parts with similar numbers cannot be directly interchanged.
• New assembly or remanufactured assembly are optional. For reman pumps, confirm factory test report and warranty period.
• Replace full seal kit during installation, inspect hydraulic oil and suction filter synchronously to prevent premature failure of new pump.
• Inspection on arrival: Check housing for dents and cracks, intact oil port threads and legible nameplate. Conduct no-load test before installation to check pressure and noise.
• Storage requirement: Store in dry and shaded area, seal oil ports for dust and moisture protection.
