DRIVE SYSTEM
9. If necessary, the bushing can be replaced. Use
the proper size driver to remove and install the
bushing. Coat the outer surface of the bushing
with Loctite 271 before pressing it into position.
Check the fit of the new bushing to the hub.
10. Check the condition and measure the inside
diameter of the bushing (Figure 72) in the slid-
ing sheave. Record the measured diameter.

11. Check the condition and measure the out-
side diameter of the hub on the belt side of the
fixed sheave (Figure 73).
12. Subtract the hub outside diameter measured
in Step 11 from the bushing inside diameter
measured in Step 10. The difference (clearance)
should not exceed 0.5 mm (0.020 in.), but the
installed bushing should move easily on the hub.
13. If necessary, the bushing can be replaced.
Use the proper size driver to remove and install
the bushing. Coat the outer surface of the bushing
with Loctite 271 before pressing it into position.
Check the fit of the new bushing to the hub.
14. Inspect the spring (Figure 74) for cracks or
distortion. Install a new spring if necessary. Re-
fer to Table 6 for original application.
NOTE
Spring failure is usually caused by the
constant twisting action that occurs dur-
ing normal clutch operation. As the
spring in the driven pulley weakens, it
will allow the driven sheaves to separate
quicker. This condition can be noticed
when riding up steep grades or in deep
snow. The machine will be slower and
have less pulling power.
