What it does

A failing balancer can throw the belt or upset timing marks, so it is worth replacing when you see cracks or wobble. 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

  • Use a proper installer tool rather than hammering the balancer onto the crank.
  • Front crank seal: Replace it while the balancer is off.
  • Drive belt: A fresh belt goes on after.
  • 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.
