Symptoms:

  • OD roller clutch failure
  • Aftermarket replacement bushings are a poor fit in output shaft housing

Cause:

Output shaft housing bore varies in diameter, resulting in inconsistent bushing fit.

Correction:

Machine the output shaft bushing housing I.D. and install the Sonnax precision bushing.

The sprag pilot bushing bore found in '88-later listed Chslyer units' overdrive output shafts can vary in diameter by .011". This variation may result in loose-fitting replacement bushings. You can restore overrunning clutch and output shaft operational clearances by machining the output shaft and installing Sonnax oversized bushing 12509-01.

  • Save otherwise good output shafts which are becoming more expensive and harder to find
  • Restores correct clearance when the output shaft housing bore is machined to accept the bushing

Installation requires that the output shaft bushing bore be machined oversized.
