Input Shaft Assembly 1. If the input bearing was removed, press a new one into the gearcase using an arbor press. Press only on the outer race or bearing damage may result. 2. Slide the input shaft and pinion through the ball bearing and assemble the spacer and two pulley halves as shown in Figure 126. Install a flat washer and a nylon locknut finger tight. 3. The input pulley nut can be tightened after complete transmission assembly, or at this point using the process in step 3, under Disassembly, page 4-7. 4. Slip the shift fork into the slot on the shift collar and place the shift fork and output shaft assembly into the transmission. Note: The long end of the shift fork shaft should go through the hole in the gearcase. Make sure that the output bushings are trapped in the proper locations. Note that the larger output bushing holes on the longer end of the shaft and the shorter output bushing goes on the shorter end of the shaft. 5. Slide the yoke bushing onto the lower end of the shift fork, then secure the shift fork with the white nylon shift fork retainer (Fig. 127). A. Pulley B. Spacer Fig 126 C. Ball bearing D.
