Key Purchasing Considerations

- New or remanufactured assemblies must include bench test reports for pressure, output torque, and internal leakage
- For remanufactured units, confirm replacement of pistons, valve plate, planetary gears, bearings, and all oil seals
- Inspect housing for cracks and verify intact oil seals upon arrival. Protect ports to prevent contamination
- Secure assembly during transportation to avoid impact damage to output shaft and precision gear components
- Clean hydraulic pipelines before installation, replace hydraulic filters, and properly bleed air from system
- Test travel speed, climbing torque, and brake performance; check for oil leakage and crawler deviation after installation
