Pumps with wear or damage to the face of the pump pocket cannot be repaired using these parts. Replace the pump.
Chrysler 68RFE pump bodies are frequently found to have a scored bearing surface or pump wear and fractures where the center gear drive flange passes through the pump. The Sonnax center pump gear 72530B-02 and/or bushing 72530B-03 salvages pumps with this type of wear. The score damage is machined out of the pump when the center pump gear bore is oversized to accept a precision, steel-backed aluminum bushing.
Pumps with worn center pump gear bores must be machined to 2.172" +/- .0005" prior to bushing installation.
