2. Place the box on the workbench with the pallet facing down.

4. Before disassembling, measure the axial clearance of the input shaft to determine whether the adjusting shim needs to be replaced (this does not apply when replacing important parts). The adjusting shims are located between the reaction shaft support and the rear clutch bracket, and between the reaction shaft support and the front clutch bracket. Mount a dial indicator with a special tool on the transformer housing and position the measuring pointer on the end of the input shaft (Figure 11.115). Press the input shaft with pliers and pull it out to obtain the axial clearance and record it.
