Product Q&A

Where can I get the pulley?Gray J.Jun 26, 2020
Best Answer:If it is a ZF pump, then Dorman 300-149 should fit as long as the shaft diameter is .663. The non-ZF pump that has the retainer spring has a smaller shaft and Dodge no longer supports that pump. Dorman does not make a pulley that fits the older pump.

The pulley fits on the power steering pump but the pulley gets in the way of the crank like there is no room for the belt to be out back on.why is it doing that?TonylukeMar 01, 2021
Best Answer:Hi Antonio, This occurs when pulleys become “tilted” because their shafts are not parallel. Worn bushings and bearings can allow rotating shafts to become cockeyed in their bores and affect the belt.
