4. Route the belts to the proper pulley sheaves as shown in Figure 21-15.
—CAUTION—
Do not force the belts into the pulley sheaves. Remove the idler
assemblies if necessary and the alternator lower mounting bolts
in order to install the belts.
5. Check the belt and pulley alignment of the compressor and/or alternator by the following method:
A. A datum line must be established for checking belt and pulley alignment. A nominal
dimension must be established between the forward edge of the compressor belt and the forward machined
surface of the ring gear. This dimension should be taken at the ring gear assembly where the belt is in its
sheave. The amount of misalignment can then be determined at the other pulley sheaves by using a stiff
straightedge of sufficient length to extend from the front of the ring gear to the component sheaves.
—NOTE—
Insure adequate ring gear surface contact to provide a solid base
for the straightedge.
