This is a heavy-duty bushing designed to provide a durable pivot point for the boom, arm, and bucket connections on Volvo excavators and Doosan loaders. Constructed from hardened steel and specialized wear-resistant materials, it offers superior longevity and smooth operation compared to a worn bushing that would exhibit excessive play and noise. Operators will typically hear knocking sounds during operation or notice a significant looseness in the bucket or arm movements 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.
The first indication of a failing bushing is usually a distinct knocking or clunking sound during digging or lifting operations, especially when the direction of force changes. As wear increases, this manifests as excessive play in the bucket, arm, or boom, leading to imprecise control and reduced digging efficiency. If left unaddressed, severe wear can damage the pivot pins and bores, leading to more costly repairs.
Thoroughly clean the pivot pin and the bore in the component before installing the new bushing to ensure a proper fit and prevent contamination. Use a hydraulic press to install the bushing squarely, avoiding any cocking that could damage the bushing or housing.
Inspect the corresponding pivot pins and the bores for any signs of scoring, deformation, or excessive wear that may require replacement or machining.
