6. Push the wire through the spring so that the threaded part
is exposed (fig 22).
7. Hold the threaded part and adjust the nut up or down until
the correct setting is obtained.
8. Pull the wire through the spring again. Hook the wire into
the upper part of the clutch lever.
9. Same adjustment for both sides.
10. Start the snow thrower and check that it does not rotate
when the clutch lever is up (= disengaged).If it does,
contact an authorised service station.
8.6 FRICTION WHEEL
If the snow thrower does not move forward the problem
could be the driving belt, driving control wire or friction
wheel. Check the friction wheel as follows.
8.6.1 CHECKING THE FRICTION WHEEL
1. Remove the spark plug protection.
2. Lift the snow thrower forward and rest in on the auger
housing.
3. Loosen the screws (3) and dismantle the bottom plate (2).
See fig 202.
3. Put the gear stick in bottom forward gear (one).
4. Measure the distance A between the friction wheel and
the outside of the side plate in fig. 25. The distance should
be 109.5 mm.
5. Adjustments are carried out as follows.
6. Reassemble in the reverse order.
8.6.2 ADJUSTING THE FRICTION WHEEL
Dismantle the parts and measure according to the
instructions in items 1-4 above.
1. Loosen the screws and set the friction wheel until the
measurement in item 4 above is obtained.
2. If the friction wheel is so worn that adjustments cannot be
carried out satisfactorily, replace in accordance with the
following instructions.
3. Otherwise reassemble in the reverse order after adjusting.
8.6.3 REPLACING THE FRICTION WHEEL (BLIZZARD,
SPARK)
1. Dismantle the right wheel from the shaft.
2. Loosen the screws (3) and dismantle the bottom plate (2).
See fig 20.
3. Remove the screw holding the chain sprocket (12) and
pull out the shaft (11) and remove the chain sprocket (12).
See fig 26.
4. Dismantle the two bearing mountings (16 in fig 21).
5. Dismantle the shaft and bearing mountings. Note the
location of the two washers (17 in fig 27).
6. Replace the friction wheel on its hub (fig. 28).
7. Reassemble all the parts in the reverse order. Note the
following when reassembling:
- Check that the washers (17 in fig. 27) are correctly
placed.
- Check that the washers (13 in fig. 27) are correctly
placed.
- Check that the shaft (8 in fig. 28) rotates freely.
- Check that the friction wheel and disc drive plate are
totally free from oil and grease.
8.6.4
REPLACING THE FRICTION WHEEL
(UNLIMITED)
1. Disassemble the differential, see 8.7.2.
2. Dismantle the two bearing mountings (16 in fig 18).
3. Dismantle the shaft and bearing mountings. Note the
location of the two washers (17 in fig 23).
4. Replace the friction wheel on its hub (fig. 28).
5. Reassemble all the parts in the reverse order. Note the
following when reassembling:
- Check that the washers (17 in fig. 27) are correctly
placed.
- Check that the washers (13 in fig. 27) are correctly
placed.
- Check that the shaft (8 in fig. 28) rotates freely.
- Check that the friction wheel and disc drive plate are
totally free from oil and grease.
8.7 DIFFERENTIAL (UNLIMITED)
8.7.1 Description
In the differential the drive force is transferred from the chain
drive to the right and left shafts via two free wheels, one for
each shaft.
This means that the outer wheel can rotate faster than the in-
ner wheel on bends.
With the differential the snow thrower is as easy to drive
around bends as straight forward.
The differential also makes the snow thrower easier to handle
on hard surfaces, for example in the garage or in the store.
8.7.2 Replacing the differential (UNLIMITED)
See fig. 7.
The differential (A) is replaced according to the following
instructions:
1. Lift the snow thrower forward and rest in on the auger
housing.
2. Disassemble the wheels.
3. Loosen the screws (3) and dismantle the bottom plate (2).
See fig. 20.
4. Disassemble the bearing housings (B) with bearings at
both sides.
5. Loosen the intermediate shaft (C) by disassembling the
bearing screws (D) at both sides.
6. Slacken the chain tension by loosening the support
bearing attachment (E). The support bearing attachment
is loosened by disassembling the two screws at the top.
7. Remove the chain from the differential.
8. Pull out the shafts from the differential and remove the
differential.
9. Check the chains. Replace if required. The chains shall
not be lubricated. They are factory lubricated. Excessive
grease can spoil the friction if it reach the friction wheel
or the friction disc.
10. Check the bearings for dissonance and uneven friction at
rotation. Replace if required.
11. Reassemble all parts in the reverse order.
