The up-grade kit No. 529012 is designed to im­
prove the action of the belt idler in all S8 Gear Drive

spring. Remove the idler spring from its anchor and

(65021).

the belt finger bolts, with a tab projecting through a
hole in the side frame. See Figure 2. Remove the nut,
lockwasher and flat washer from the belt finger;
Discard the flat washer; Install the spring anchor as
shown in Figure 2; and replace the lockwasher and
nut.

grommets, a washer and a hex nut. Assemble in the
hole as shown in Figure 3 with the cap screw on top of
the frame and both grommets under frame.

the belt as described in the Owner's Manual.
7. Check along the belts to be sure there is no
interference between belts and wire clamps on the

wobble seems to be a problem, replace the sheave.
