TRANSMISSION COVERS

All #5003 production transmissions and the early #5010 transmissions were equipped with ball bearings on the brake shaft. Late #SO10 transmissions and replacement transmissions of both models were pro-

duced with needle bearings. To insure receiving the correct side covers, please order as follows:

BRAKE SHAFTS

Original equipment brake shafts used in ball bearing type transmissions cannot be used with needle

Presently stocked brake shafts and those used in needle bearing transmissions are interchangeable.

To

install in ball bearing transmissions, use four 1197 Shim Washers between the brake shaft gear

and the left side cover plate.
