68RFE

Center Pump Gear

Part No. 72530B-02

Complaint:

  • Noise concerns
  • Pump gear wear or fracture
  • Scored surface where center gear pump pilot passes through pump body

Cause:

Excess pump body wear.


Correction:

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

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
WARNING:

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.
