Installation & Quality Guidelines
- Verify OEM part number compatibility for swing motor, reducer, and parking brake assembly
- All new or remanufactured assemblies must include bench test reports for working pressure, swing 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 oil seal integrity upon arrival
- Protect ports during handling to prevent contamination
- Secure assembly during transportation to prevent impact damage to output shaft and precision gear components
- Clean hydraulic pipelines before installation, replace hydraulic filters, and properly bleed air from system
- Post-installation testing required for swing speed, swing torque, parking brake function, start-stop impact, and oil leakage
