Failure Symptoms

Early indications of main bearing failure include knocking or rumbling noises from the engine, especially under load. If left unaddressed, this can lead to severe crankshaft damage and potential engine seizure. Continued operation risks catastrophic engine failure, resulting in extensive repair costs and prolonged equipment downtime.

Installation Tip

Ensure all bearing surfaces and crankshaft journals are meticulously cleaned and free of any debris before installation to prevent immediate damage. Never mix old and new bearings; always use the complete kit as specified.

Service Note

Inspect connecting rod bearings, crankshaft journals, and the engine oil pump and filter during main bearing replacement.
