This is a boom cylinder bushing, a crucial wear component that provides a low-friction surface for the cylinder rod to pivot within the boom structure. It is manufactured from durable materials to withstand the high loads and constant motion experienced during operation, offering superior resistance to wear and deformation compared to a worn or damaged bushing. Operators may notice increased play or looseness in the boom, audible clunking noises during operation, or a visible gap developing between the cylinder and its mounting point 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 indication of a worn boom cylinder bushing is often increased play or looseness in the boom's movement, accompanied by potential clunking sounds. As wear progresses, the gap will widen, leading to uneven stress on the cylinder and mounting points. Continued operation with a severely worn bushing can cause damage to the cylinder rod and bore, leading to costly repairs.
Ensure the cylinder mounting pins and bores are clean and free of burrs before installing the new bushing. Avoid using excessive force or hammering when pressing the bushing, as this can damage its precise dimensions.
When replacing the boom cylinder bushing, inspect the cylinder rod for scoring or damage and check the condition of the cylinder pin and mounting hardware.
