REPAIR INSTRUCTIONS 1. Install the No. 1 (upper right, when viewed from front) and No. 3 (lower) front countershaft front bearing covers and capscrews. Make sure new O-rings are in place. Tighten the capscrews to the specified torque. 514
4. Temporarily position a shim pack over one of the front countershaft rear bearing cover openings. Mark the overhang of the shim pack at the reverse idler shaft opening of the case. This helps position the reverse idler shaft and prevents bearing cover interference with the shaft. Mark all idler shaft openings.
The bearing cover fits into the flat on the idler shaft to retain the shaft and prevent it from rotating. 516
