DRIVE SYSTEM
c. Use a spring tester (Figure 41) to check the
spring pressure at specified compressed
height as listed in Table 5.
17. Inspect the buttons (A, Figure 42) and the
area of the sliding sheave where the buttons rub
(B, Figure 42). Replace the parts, as necessary.
The buttons should be replaced in sets of six.
Assembly
Refer to Figure 43 for this procedure.
1. Install the cam arm weights as follows:
NOTE
The three pivot screws that secure the
cam arm weights must be installed so the
heads of the screws are toward the direc-
tion of rotation. See Figure 44.
341
a. Insert a pivot screw (A, Figure 44) through
the attaching lug from the direction shown.
b. If equipped with two washers, install one of
the washers on the edge of the screw (B,
Figure 44), then position the cam arm
weight and second washer between the
mounting lugs and push through the pivot
screw.
c. If equipped with the clip shown in Figure
34, position the clip around the weight.
Position the clip and weight between the
mounting lugs and push through the pivot
screw.
CAUTION
Always install new self-locking nuts as
described in substep I d. Do not install
the old nuts.
d. Apply Loctite 271 (red) on the threads of a
new
locknut. Tighten the locknut until it
bottoms against the mounting lug, but do
not overtighten (Figure 45).
e. Pivot the weight back and forth to make
sure the weight moves easily and smoothly.
If the locknut is too tight, it will cause the
weight to bind and stick.
f. Repeat substeps la-e and install the other
weight assemblies.
2. Assemble the roller and bearing assembly
(Figure 32) in the spider as follows:
a. Insert a pin partway through the spider
(Figure 46).
NOTE
The washers (II, Figure 43) installed in
substeps 2b and 2d may have one metal
side and one fiber side.
If
so, install with
the fiber side against the roller and the
metal side against the spider.
b. Install one of the washers on the edge of the
pin (Figure 46).
c. Position the roller and bearing assembly
between the sides of the spider and push the
pin in far enough to hold the roller assembly
in place.
