0676886 Main Bearing Set — Cat 206 416C

This is a CAT 0676886 Main Bearing Set, essential for supporting the rotating crankshaft within the engine block and reducing friction. Manufactured to meet stringent OEM quality standards, these bearings provide optimal load distribution and durability, unlike worn bearings that can cause excessive play and oil pressure loss. Operators may observe low oil pressure warnings, increased engine noise, or rough running when this bearing set 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

A failing 0676886 main bearing set may initially cause a drop in oil pressure, especially at higher engine speeds, and audible knocking noises from the lower engine. If left unaddressed, the bearing can fail completely, leading to severe crankshaft and engine block damage. Continued operation risks complete engine seizure and extensive repair costs.

Installation Tip

Ensure the crankshaft journals and bearing surfaces are meticulously cleaned and free of any debris or burrs before installation. Use the correct assembly lubricant on the bearing surfaces and crankshaft journals.

Service Note

When replacing main bearings, it is crucial to inspect the crankshaft for straightness and wear, and to check the oil pump and oil filter for any signs of blockage or damage.
