CAUTION:
Do not overtighten the screws. You could crack the sheave
hub, or break off the screws. If the sheave pulls up against the bushing
flange, the shaft diameter is too small.
5. Tighten the cap screws evenly, a quarter turn at a time, to the
specifications in Table 7-1. This will pull the sheave and bushing
together. Maintain a gap of 3 − 6 mm (0.125 − 0.25 in.) between the
bushing flange and the sheave.

6. Check again to make sure the motor and fan sheaves are parallel with
each other and to the dimensions in Figure 7-6. If they are not, separate
the bushing and sheave and repeat the installation steps.
7. Install the V-belts as described in the V-Belt Replacement procedure.
