This is a CAT Boom Cylinder Bushing, essential for the hydraulic system's boom articulation. It provides a wear surface for the cylinder rod, ensuring smooth and controlled movement. A worn bushing will exhibit excessive play, leading to imprecise boom control and potential damage to adjacent components.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
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 noticeable play or looseness in the boom's movement. If ignored, this play will increase, leading to jerky operation and potential damage to the cylinder rod and seals. Continued operation with a severely worn bushing risks uncontrolled boom movement and damage to the hydraulic system.
Ensure the cylinder bore is thoroughly cleaned of all old material and debris before attempting installation. Avoid using excessive force or improper tools, which can damage the new bushing or the cylinder housing.
Inspect the hydraulic cylinder rod for scoring and the cylinder seals for leaks when replacing the boom cylinder bushing.
