CATBearing & Bushing

4M5317 Bushing — Cat 320C 320D

This is a durable bushing designed to serve as a critical wear point in the articulation and pivot systems of heavy equipment. Manufactured to precise dimensions and material specifications, it provides a long-lasting bearing surface, significantly outperforming a worn bushing that would allow excessive movement. Operators may experience increased looseness in the machine's steering or implement control, accompanied by potential squeaking or clunking sounds during operation, indicating a failing bushing.

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 wear include increased slack or play in the machine's articulated joints, leading to less precise control. As the bushing wears further, this play can cause noticeable clunking or grinding noises during operation. Continued use with a worn bushing can result in accelerated damage to the mating pin and bore, potentially affecting the structural integrity of the linkage.

Installation Tip

Ensure the bore and the new bushing are completely free of dirt and old grease before installation. Do not use a hammer to drive the bushing in; use a proper press or driver.

Service Note

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