BULLETIN COVERS:

New Nibron coating for batwing and round washers used on input carrier pinions.
DATE OF PRODUCTION CHANGE: (Figure 1)

Input carriers with the new Nibron coated pinion washers were built into THM 125/125C transaxles starting with Julian Date 355 (December 21, 1987).
SERVICE ACTION:

The pinion washers (round and batwing) cannot be serviced individually.

The input carrier assembly should be inspected for:

Pinion Damage Pinion Tilt Pinion End Play - Use a feeler gage - end play range 0.24 - 0.69 mm (0.009" - 0.027")

If pinion end play is not in this range a new input carrier should be installed.

When servicing any THM 125/125C transaxle and inspection of the input carrier reveals any of the input carrier pinion washers are worn and/or missing, a new input carrier must be installed. This input carrier with new Nibron coating may be used on all past models.
