Symptoms:

  • Loss of lubrication oil to planetaries
  • Reverse drum, retainer & planet failure

Cause:

Excessive clearance between the overdrive piston retainer and intermediate shaft reduces lube flow to the gear train.

Correction:

Seal compensates for variations in case I.D. Oil is delivered to maximum load points on shaft. Optional oversized reverse drum journal allows salvage of reverse drum.
