CATBearing & Bushing

8N8223- 060 Bearing — Cat 120G 12G

This is an engine bearing, specifically sized with a 0.060 inch undersize, designed to support rotating components like the crankshaft or camshaft. It plays a vital role in minimizing friction and wear, ensuring the smooth operation of the engine's internal rotating assembly. A worn or damaged bearing will manifest as increased engine noise, reduced oil pressure, and potential performance issues, necessitating replacement to prevent severe engine damage.

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

A failing engine bearing may first present as a dull knocking sound that increases with engine speed. If ignored, this can escalate to significant oil pressure loss and potentially cause catastrophic damage to the crankshaft and engine block.

Installation Tip

It is critical to ensure the crankshaft journals are precisely measured and confirmed to be within the service limits for a 0.060 undersize bearing. Never install an undersize bearing on an unworn or standard-sized journal.

Service Note

When replacing bearings, always inspect the crankshaft for wear, straightness, and proper oil clearance using Plastigage.
