Product Description:

Original Rexroth A11VO75LR3/10R‑NZD12N00 Axial Piston Variable Pump, OEM Part No: R902208656

This is genuine Bosch Rexroth swash‑plate axial piston variable pump, designed for open‑circuit hydraulic systems of mobile construction machinery. Model A11VO75LR3/10R‑NZD12N00 adopts LR3 power control, delivers stable high‑pressure output, high volumetric efficiency and low internal leakage under continuous heavy‑load working conditions. Widely used as main hydraulic pump for medium‑size excavators and other engineering equipment.

Main Technical Data

‑ Model: A11VO75LR3/10R‑NZD12N00 ‑ OEM Part Number: R902208656 ‑ Displacement: 75 cm³/rev ‑ Rated pressure: 350 bar, Max peak pressure:400 bar ‑ Control mode: LR3 power control ‑ Rotation: Clockwise

Important Reminder: A11VO75 has many different code variants. Please double‑check the full model code, part number, port layout and shaft spline information of your original pump before placing order to avoid wrong item.

Installation Notes

  1. Check pump body for shipping damage, confirm full model number and OEM code match your original pump.
  2. Thoroughly clean mounting flange, oil ports and connecting pipelines, remove dirt and metal debris.
  3. Replace all O‑rings and gaskets, never reuse old sealing parts.
  4. Connect hydraulic pipes strictly according to port marking. Wrong connection will cause equipment malfunction.
  5. Tighten mounting bolts with cross‑torque following official service manual requirement.
  6. Fill clean hydraulic oil into pump housing before startup. Dry‑running will permanently damage internal components.
  7. Flush hydraulic system and replace filter after installation.
  8. Run engine at low idle speed to bleed air, do not operate full‑load at initial commissioning.
  9. Test all functions, check oil leakage and abnormal noise. Stop operation once any abnormality occurs.

‑ Caterpillar: 320GC, 320GX, 323GC, 323GX

Interchangeable part number: 536‑7286Alibaba.co...

Important Reminder

Please confirm part number, shaft spline and port position before placing order. Different serial number machines may have different motor versions.

Installation Notes

  1. Inspect motor for shipping damage before installation. Verify part number, spline and port match original unit.
  2. Clean mounting surface thoroughly, remove dirt and metal debris.
  3. Replace all O‑rings and seals. Do not reuse old seals.
  4. Connect hydraulic hoses strictly according to port marking. Wrong hose connection will cause swing failure.
  5. Torque mounting bolts cross‑referenced following machine service manual specification. Thread locker is recommended.
  6. Fill clean hydraulic oil into motor housing prior to startup. Dry running will damage internal parts permanently.
  7. Replace hydraulic filter and flush pipeline to clear metal contaminants.
  8. After installation, run machine at low idle speed to bleed air from hydraulic circuit. Do not apply full‑load swing immediately.
  9. Check oil leakage, abnormal noise and vibration during test run. Stop operation once any abnormality appears.
  10. Ensure case drain line is unobstructed, blocked drain line will blow out seals and destroy motor.
