Carefully
position
the hex shaft downward
and to the left
before carefully
sliding the friction
wheel assembly
off the
shaft. See Fig. 7-10.
NOTE: If you're replacing
the friction
wheel assembly
as a
whole, discard the worn part and slide the new part onto
the hex shaft.
Follow the previous steps in reverse order to reassemble
components. If you're disassembling the friction wheel and
replacing only the rubber ring, proceed as follows:
1.
Remove the four screws which secure the friction wheel's
side plates together. SeeFig. 7-11
F
Figure 7-11
2.
Remove the rubber
ring from between
the plates.
3.
Reassemble
the side plates with a new rubber
ring.
NOTE:When
reassembling
the friction
wheel assembly,
make sure that the rubber
ring is centered
and seated
properly
between
the side plates. Tighten
each screw
only one rotation
before turning
the wheel
clockwise
and proceeding
with the next screw. Repeat this process
several times to ensure the plates are secured with equal
force (between
6 ft-lbs and 9 ft-lbs).
4.
Slide the friction
wheel assembly
back onto the hex shaft
and follow
the steps above in reverse order to reassemble
components.
