Excess pump body wear.


Salvage the pump and restore normal operation by installing Sonnax center pump gear.


Inspect pump bore and pump pocket face below the center gear. Damaged bores can be corrected using center pump gear bushing 72530B-03. Damaged pockets cannot be repaired using these parts. Replace the pump.


Center Pump Gear
Part No. 72530B-02

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.

  • Allows salvage of pump bodies scored at center gear bearing surface
  • Redesigned center gear drive flange reduces turbine hub engagement play and noise
  • The correctly installed steel-backed aluminum alloy precision bushing extends pump life
