Questions about this item

Does the 594-109 balancer require a specific crankshaft bolt or washer not included in the box?

The Dorman 594-109 harmonic balancer is sold as the balancer assembly only; verify your vehicle service manual for the correct crankshaft bolt, washer, and torque specification before installation.

Will the 594-109 fit the original accessory drive pulleys and belt on my engine?

This gray balancer is designed to match the factory diameter and groove profile for the listed applications, so the existing serpentine or V-belt pulleys should align without modification.

How can I confirm the 594-109 is seated and running true after I torque the centre bolt?

After torquing to the manufacturer’s specification, spin the engine by hand and check for wobble at the outer ring; a dial indicator on the groove face should show minimal run-out, and the timing marks must line up with the pointer at TDC.
