This Main Bearing Set is essential for the proper functioning of the engine's crankshaft, supporting its rotation while managing significant combustion forces. Manufactured to meet exacting OEM quality standards, this set provides superior wear resistance and load-bearing capacity over worn or damaged bearings. Operators may notice a drop in oil pressure, increased engine noise, or visible smoke from the exhaust when these bearings begin to fail.
Always verify with serial number before ordering.

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.
Early failure signs include a knocking or rattling sound from the engine, particularly under load, and a potential drop in oil pressure. If ignored, bearing material can break away, scoring the crankshaft and leading to severe engine damage. Continued operation risks catastrophic engine failure and extensive repair costs.
Ensure the crankshaft journals and bearing surfaces are meticulously cleaned and free of any debris or scoring. Never reuse old bearing bolts; always use new ones with the correct torque specifications.
Inspect the crankshaft journals for any signs of wear, scoring, or out-of-roundness, and check the oil pump for proper function.
