38080, 38085
These models work as previously described in the
Introduction, except there is a separate drive plate for
reverse. When the shift lever is pulled into reverse, the
friction wheel is pulled to the rear until it contacts the
small reverse plate. The drive will then operate in
reverse (Figure 71).

Remove the klik pins and both wheels.
Each end of the axle is supported by a bearing
which is attached to the chassis by two thread
forming screws. At minimum, the screws must be
removed from the bearing on the left side in order
to remove the axle. The right side axle bearing
can also be removed (Figure 73).
