This boom cylinder bushing is a critical wear component that supports the pivot pin within the boom cylinder assembly of Volvo excavators. It is engineered from hardened steel to withstand high loads and friction, providing a smooth pivot action unlike a worn bushing that can cause binding and excessive pin wear. Operators may observe increased play or looseness in the boom, noisy operation during lifting, or premature wear on the cylinder pin and eye.

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.
Increased play or looseness in the boom assembly is the initial indicator of a worn bushing. Continued operation will lead to accelerated wear on the cylinder pin and the boom eye, potentially causing binding during movement. Neglecting replacement can result in damage to the cylinder rod and housing, requiring more extensive repairs.
Ensure the cylinder bore is thoroughly cleaned of all old material and debris before pressing in the new bushing. Avoid using excessive force or hammering, which can damage the bushing or the cylinder housing.
Inspect the boom cylinder pin and the cylinder eye for wear or damage whenever replacing a bushing.
