What it does
Worn bearings cause knocking and low oil pressure, and they are always replaced in a rebuild. 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.
- Put the new part next to the old one and compare the shape, mounting points and connections before you install it.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
