The OE plastic 3-tab washers break or melt under normal operation. Sonnax offers a 3-tab bimetal thrust washer and shim kit 54701-03K to replace the OE plastic washers in both pump and center support locations.

  • The steel tabs on the Sonnax thrust washer eliminate breakage.
  • The bronze thrust surface will not melt like the OE plastic thrust washers.
  • Shims provide more flexibility when setting endplay and allow for rebuilding units after thepump has been resurfaced. The Sonnax washer kit can be stacked to cover a build height from .075" through .125" in .010" increments.
  • This kit contains enough parts for pump and stator support locations.

The Sonnax thrust washer kit cannot be used to replace late style no-tab thrust washers.
