Center Pump Gear

Find a Distributor

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

Pumps with worn center pump gear bores must be machined to 2.172" +/- .0005" prior to bushing installation.

  • Material: Steel backed aluminum
  • Bushing Style: Precision
