Belt Replacement
Both drive belts carry a similar load, and should wear at a
very similar rate. If one of the belts should break or one or
both appear worn to the point of needing replacement, it
may be preferable to replace both belts simultaneously, as
the repair is somewhat involved.
To replace the belts begin by removing the air cleaner
cover, and disconnect the throttle wire and stop cord wire
from engine.
Next, remove the 2 top engine mount bolts with their
spacers, as well as the fender (Fig. 17).
Loosen and remove the belt tension adjuster from the left
side of the frame, as well as the three screws that secure
the left hand side plate to the frame (Fig. 18)
With the side plate removed, it is possible to remove both belts from the
frontward pulleys. Inspect the pulleys (Fig. 19) to ensure that they are
not damaged. Also, inspect the bearings on the pulley shaft as well as
the support bearing that rides in the side plate. If integrity of any
bearings are questionable – install new ones.
If it is necessary to replace the large, rear belt, it will require that the
rear wheel be completely removed.
Carefully position new belt(s). Note that the lower section of the large,
rear belt must ride on top of the idler arm ( with two ball bearings in
tandem), protruding from the side plate.
Carefully adjust the tension of the belts as indicated in the previous
section.
