What it does
Engine bearings let the crankshaft and rods spin on a thin film of oil. Using the correct part for your exact engine keeps oil pressure, sealing and timing where the engine was designed to run, and doing related parts at the same time saves taking it apart twice.
Installation & tips
- Check clearances with plastigage or a micrometer, and use assembly lube on every bearing.
- Oil pump: Often replaced together.
- Gasket set: The engine comes apart for bearings.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
