Product Description
Bulldozer Komatsu D155A-6 D155A-6R Hydraulic Pump Main Pump Piston Pump 708-1L-00670 708-1L-00671
Common Failures
  • 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 fails to reach rated value.
  • Slow machine movement: Reduced volumetric efficiency of hydraulic pump and insufficient output flow; clogged suction filter element, excessive suction resistance.
  • Excessively high hydraulic oil temperature: Severe internal leakage inside pump and increased frictional heat; incorrect 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.
Purchasing Recommendations
  1. Verify the stamped part number on old pump and bulldozer model D155A-6 before placing order. Similar part numbers within the same series cannot be directly interchanged.
  2. New assembly or remanufactured assembly are available. For reman pumps, confirm factory test report and warranty period.
  3. Replace full seal kit during installation, inspect hydraulic oil and suction filter to avoid premature wear and damage of new pump.
  4. Inspection upon arrival: Check pump housing for dents and cracks, intact oil port threads and legible nameplate. Perform no-load test before installation to check pressure and noise.
  5. Storage requirement: Store in dry and shaded area, seal oil ports against dust and moisture.
