Troubleshooting & FAQ
What are the signs of a failing main bearing?
Common symptoms include a deep, knocking sound from the engine that increases with RPM, low oil pressure, and the presence of metallic particles in the engine oil and filter.
Is this a complete kit for the entire engine?
Yes, this is a complete main bearing kit containing all the bearing shells required for the crankshaft on compatible engine models.
Can I install this kit myself?
This is a complex task that requires specialized tools (like a torque wrench and micrometers) and a high degree of mechanical expertise. Professional installation is strongly recommended to ensure correct tolerances and engine safety.
What causes main bearings to fail?
The most common causes are oil starvation, oil contamination (with fuel, coolant, or debris), overloading the engine, and improper installation.
Is any break-in period required after installation?
Yes. After installation, it's advisable to run the engine at varying, low-to-mid RPMs with no heavy load for the first few hours of operation to allow the new bearings to seat properly. Avoid full-throttle operation initially.
