Maintenance & Replacement

Compare clearance, condition and sealing each time, and renew the unit when measurement or appearance moves outside the maker's range. Early signs it may need attention: Unusual noise, poor performance or a developing leak that points at the failing component; Recurring minor faults on nearby components that trace back to this unit degrading the circuit; Inspections that show scoring, pitting, distortion or hardening on the working surfaces.
Installation Essentials
Work on a clean machine with the engine off and the relevant system drained or depressurised as required, and confirm the part number against your machine model and serial number before ordering. Verify batch condition and surface finish on delivery, and flag anything that looks off before fitting rather than after. After installation, run the machine and check for leaks, unusual noise or abnormal travel before returning it to service, and retighten where the manual calls for it after the first hours of operation.
