This sleeve bearing bushing is a critical component within the pivot or boom system of Volvo excavators, designed to reduce friction and wear between moving metal parts. It is manufactured to stringent OEM standards, ensuring superior durability and performance compared to worn or damaged bushings that can lead to increased play and reduced operational precision. Operators may notice increased looseness in the boom or bucket, audible squeaking or grinding noises during operation, and a general decrease in the machine's responsiveness when this bushing begins to fail.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Initial signs of a failing sleeve bearing bushing include increased play or looseness in the excavator's boom or bucket movements. If left unaddressed, this wear will accelerate, leading to noisy operation and potential damage to adjacent components. Continued operation with a severely worn bushing risks compromising the structural integrity of the linkage system.
Ensure the mating pin and the bore of the component receiving the bushing are thoroughly cleaned of all old grease and debris before installation. Avoid forcing the bushing into place, as this can damage its structure or the housing.
Inspect the pivot pin and the surrounding linkage components for signs of wear or damage during bushing replacement.
