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.
• 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.
