Applicable Models & Applications
This work-equipment component is used on Caterpillar machines, taking mechanical load in the bucket, boom, arm or linkage. Suitable for the corresponding machine model and configuration — please verify the machine model, serial number and part number match before ordering.
Maintenance & Replacement
Inspect pins, bushings, welds and wear plates at the recommended interval and grease pivot points on schedule; replace worn pins/bushings before they enlarge bores and cost a full frame repair. Early signs it may need attention: A growing rattle or clank in the bucket/boom pivot as pin-bushing clearance grows; Elongated eyes or hairline welds around the bucket and linkage; Uneven tooth/wear-plate wear that loads the linkage off-centre.
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.
