This is a cylinder bushing, a critical component that provides a wear surface and alignment for the pivot point of hydraulic cylinders, typically found in excavator boom, arm, or bucket linkages. It is constructed from hardened steel to withstand high loads and friction, offering superior durability over a worn bushing that can cause excessive play and noise. Operators may notice increased noise or vibration during operation, or the linkage may feel loose and imprecise.
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 initial symptom of a worn bushing is noticeable play or looseness in the hydraulic linkage. If ignored, this wear will accelerate, leading to increased noise, vibration, and potential damage to the cylinder eye and pivot pin. Continued operation with severely worn bushings can compromise the structural integrity of the linkage assembly.
Ensure the cylinder eye and pin are thoroughly cleaned and free of debris before pressing in the new bushing. Do not attempt to force the bushing if it does not seat properly; check for obstructions or misalignment.
Inspect the corresponding pivot pin and cylinder eye for wear or damage when replacing the cylinder bushing.
