Traction Drive Systems
6.
The axle can now be removed from the chassis.
Inspect the gear, the roll pin, and the areas where
the bearings contact the axle for damage or
severe wear. Remove the thrust washers from
either end of the axle. The purpose of the roll pin
and thrust washers is to limit the side to side
movement of the axle.
10. The pivot shaft, which contains the friction wheel,
is retained by two shoulder bolts. They pass
through the side plate, into the ends of the shaft.
Remove these two bolts and the pivot assembly
will slide out of the chassis (Figure 76).

Disconnect the two clevis pins on the shift linkage
rods.
Next to the friction wheel is a large eyebolt, which
is connected to the shift linkage (Figure 74).
Remove the flange nut and washer from the end
of the eyebolt. Note the location and type of
washers. You should be able to slip the linkage off
of the eyebolt. If not, loosen the shoulder screw
that the linkage pivots on.

screws securing the hex shaft bearings. Slide
the bearings off the ends of the hex shaft.
C. The hex shaft can now be removed from the
pivot assembly.

the four screws and lock nuts connecting it to
the traction drive hub.
