Figure 1-14
NOTE: Engaging auger control will ease
removal and reinstallation of belt.
8.
Replace auger belt by following
instructions in reverse order.
NOTE: Make sure to reinstall shoulder
bolt (a) and reconnect spring to frame
after installing a replacement auger belt.
Refer to Figure 4-13.

NOTE: See your authorized service dealer to
have drive belt replaced or contact Customer
Support.
Friction Wheel Inspection (Steerable 500
and 800 Series & Non-Steerable Single
Speed 600 Series)
If unit fails to drive with drive control lever
engaged, and performing drive control cable
adjustment fails to correct problem, the
friction wheel may need to be replaced.
NOTE: Special tools are required and several
components must be removed in order to
replace the unit’s friction wheel rubber. See
your authorized service dealer to have friction
wheel rubber replaced or contact Customer
Support.
To inspect friction wheel, proceed as follows:
1.
Allow engine to run until it is out of
fuel. Do not attempt to pour fuel from
engine.
2.
Carefully pivot unit up and forward so
that it rests on auger housing.
3.
Remove frame cover from underside
of unit by removing four self-tapping
screws which secure it. See Figure 4-4.
4.
Inspect friction wheel for signs of wear
or cracking.
Friction Wheel Removal (Multi-Speed
Non-Steerable 600 Series)
If unit fails to drive with drive control lever
engaged, and performing drive control cable
adjustment fails to correct the problem,
friction wheel may need to be replaced. Follow
the instructions below. Examine friction wheel
for signs of wear or cracking and replace if
necessary.
1.
Allow engine to run until it is out of fuel.
Do not attempt to pour fuel from engine.
2.
Place shift lever in first Forward (F1)
position.
3.
Carefully pivot unit up and forward so
that it rests on auger housing.
4.
Remove frame cover from underside of
unit by removing self-tapping screws
which secure it. See Figure 4-4. Remove
right-hand wheel by removing screw
and bell washer which secure it to axle.
See Figure 4-15.

5.
Carefully remove hex nut (a) which
secures hex shaft to frame and lightly
tap the shaft’s end to dislodge ball
bearing from right side of frame. See
Figure 4-16.

NOTE: Be careful not to damage threads
on shaft.
6.
Carefully position hex shaft downward
and to left before carefully sliding
friction wheel assembly off shaft.
See Figure 4-17.
Figure 1-17
NOTE: If you’re replacing friction wheel
assembly as a whole, discard the worn
part and slide new part onto hex shaft.
7.
Follow previous steps in reverse order to
reassemble components.
NOTE: Make sure shift lever pin is in place
in bearing housing. See Figure 4-16 inset.
8.
Perform Drive Control test shown on
page 15.
If you’re disassembling friction wheel and
replacing only rubber ring, proceed as follows:
NOTE: Not all friction wheels are serviceable.
If this is the case, simply replace friction wheel
assembly.
1.
Remove four screws (a) which secure
friction wheel’s side plates together.
See Figure 4-18.

2.
Remove rubber ring from between the
plates.
3.
Reassemble side plates with a new
rubber ring.
NOTE: When reassembling friction
wheel assembly, make sure that rubber
ring is centered and seated properly
between the side plates. Tighten each
screw only one rotation before turning
wheel clockwise and proceeding with
next screw. Repeat this process several
times to ensure plates are secured with
equal force (between 145-115 in-lbs).
4.
Slide friction wheel assembly back
onto hex shaft and follow the steps
above in reverse order to reassemble
components.
5.
After replacing friction wheel, perform
Drive Control test shown on page 15.
NOTE: Make sure shift lever pin is in place
in bearing housing. See Figure 4-16 inset.
Hydro Transmission (If Equipped)
NOTE: See your authorized service dealer
to have the Hydro Transmission serviced or
contact Customer Support for assistance and
the name of your nearest servicing dealer.
