This is a hardened steel hydraulic cylinder bushing designed to provide a wear surface for the pivot points of hydraulic cylinders on Volvo excavators. It ensures smooth articulation and prevents excessive wear on the cylinder rod and housing, maintaining precise movement. Manufactured to strict tolerances, this bushing offers superior durability compared to worn components that develop excessive play. Operators may notice increased play or looseness at the pivot points, a clunking noise during operation, and potential damage to adjacent components if the bushing is severely worn.
Always verify with serial number before ordering.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first sign of a worn bushing is increased play or looseness in the hydraulic cylinder's pivot joint, which may be accompanied by a noticeable clunking sound during operation. As wear progresses, this looseness can lead to uneven stress on adjacent components, potentially causing damage to the cylinder rod or mounting brackets. Ignoring severe bushing wear can result in unpredictable machine movement and increased risk of component failure.
Ensure the cylinder mounting points are clean and free of burrs before attempting to press in the new bushing. Use a proper press and appropriate tooling to avoid damaging the bushing or the cylinder housing.
When replacing cylinder bushings, always inspect the corresponding pins and cylinder rod for wear or damage that may have contributed to the bushing failure.
