Applicable Models & Applications

Maintenance & Replacement
Inspect the part at the manufacturer's recommended interval and replace it while adjacent components are being serviced; never reuse worn or suspect parts, and torque all fixings to the stated figure. Early signs it may need attention: A machine that runs, but only after workarounds — flags, shims or extra torque — that mask a tired part; Visible wear, corrosion or damage that is accelerating on the part and its neighbours; A part that no longer holds its original clearance, tension or seal after repeated service intervals.
Installation Essentials
Confirm the part number against your machine model and serial number before ordering. Work on a clean machine, with the engine off and the relevant system depressurised or drained first. Fit new seals, gaskets or O-rings and torque every fastener to the manual's figure. 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.
