BELTS. (Refer to Figure 13-10.)
a. Remove the old belts by removing the spinner, propeller, nose cowl. right front
baffle, starter ring gear assembly and drive belts.
b. Place the new belt or belts in, their appropriate positions on the starter ring gear
sheaves.
c. Reinstall the starter ring gear assembly, propeller and spinner.
d. Route the belts to the proper pulley sheaves as shown in Figure 13-10.
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.
e. Check the belt and pulley alignment of the compressor and/or alternator by the
following method:
1. A datum line must be established for checking belt and pulley alignment. A
nominal dimension must be established between the forward edge of each belt and the
forward machined surface of the ring gear. This dimension should be taken at the ring gear
assembly where the belts are in their sheaves. 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.
