Differential Kit Disassembly
Figure 120 See Figure 122.
The Power Shift differential
kit,
Model
38038,
can greatly
improve maneuverability of the Power Shift snow-
thrower.
It
allows one wheel to rotate faster than the
other wheel in turns. The advantages of the differential
kit
will be most noticable when traction is good and the
snowthrowing job requires many turns.
However, as with automobile differentials, when one
wheel loses traction, the other
will
not drive. To address
this issue, the Power Shift differential kit was designed
with the capability of being easily locked to provide rigid
axle performance when conditions dictate.
1. Remove the four nylon locknuts securing the
sprocket to the differential and remove the
sprocket.
2. Drive the roll pin from the locking cover side
of
the
axle and remove the locking cover.
3.
Remove the
two
keys from the locking cover side
of the axle.
4.
Remove the four nuts and allen head capscrews
securing the
two
halves of the differential and split
the differential.
