This is a boom cylinder bushing, a crucial wear component that provides a low-friction pivot point for the boom cylinder on Volvo excavators. It is manufactured from high-strength, wear-resistant material to meet demanding operational standards, outperforming worn or damaged bushings. Operators may notice increased play or looseness in the boom, audible clunking noises during operation, or difficulty in precise boom control when this bushing is worn.

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 boom cylinder bushing is excessive play or looseness in the boom assembly, which can manifest as a clunking sound. If ignored, the wear will accelerate, leading to increased stress on the pivot pin and surrounding structures, potentially causing damage. Continued operation with severely worn bushings can compromise the structural integrity of the boom mounting.
Clean the bore of the cylinder and the pivot pin thoroughly before installation to ensure a smooth fit and prevent premature wear. Avoid using excessive force or improper tools when pressing the bushing, as this can damage the component or the cylinder housing.
Inspect the pivot pin and the corresponding bushing on the opposite side of the cylinder for wear, and check the cylinder rod for scoring or damage.
