What it does
Crank work comes with bearings, balancing and careful measurement. 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
- Have the rotating assembly balanced if you change pistons, rods or the crank.
- Main and rod bearings: Always new with a crank.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
