CATBearing & Bushing

3B6768 Bushing — Cat 320C 320D

This is a high-quality bushing designed to function as a critical wear component within the linkage and pivot points of heavy machinery. It is manufactured to meet stringent material and dimensional standards, ensuring superior durability compared to a worn or damaged bushing that would exhibit excessive play. Operators may notice increased looseness in the equipment's movement, audible clunking noises during operation, or a general degradation of control precision when this bushing begins to fail.

Installation & Application Notes

Never strike bearings directly — use a bearing press or driver set. Heat housing (not bearing) to ease installation. Replace bearings in sets where applicable. Check housing bore diameter before fitting — out-of-round bores destroy new bearings.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Initial signs of failure include noticeable play in the connected components, leading to imprecise machine movements. As wear progresses, this play increases, potentially causing audible knocking or clunking sounds during operation. Continued operation with a severely worn bushing can lead to accelerated damage to adjacent components and compromised operational control.

Installation Tip

Ensure the bore and the new bushing are clean and free of debris before attempting installation. Avoid using excessive force or hammering, which can damage the bushing or the surrounding housing.

Service Note

Inspect the mating pin and the bore for any signs of scoring, wear, or deformation, and replace if necessary.
