- Check that the washers (17 in fig. 28) are correctly
placed.
- Check that the washers (13 in fig. 28) are correctly
placed.
- Check that the shaft (8 in fig. 29) rotates freely.
- Check that the friction wheel and disc drive plate are
totally free from oil and grease.
8.6.4 Byte av friktionshjulet (FLAKE, POWER)
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. 29).
5. Reassemble all the parts in the reverse order. Note the
following when reassembling:
- Check that the washers (17 in fig. 28) are correctly
placed.
- Check that the washers (13 in fig. 28) are correctly
placed.
- Check that the shaft (8 in fig. 29) rotates freely.
- Check that the friction wheel and disc drive plate are
totally free from oil and grease.
8.7 DIFFERENTIAL (FLAKE, POWER)
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 (FLAKE, POWER)
See fig. 31.
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.
8.8 REPLACING THE SHEAR BOLTS
The auger is fastened to the shaft by special bolts (20 in fig.
14) that are designed to break if something gets stuck in the
auger housing.
Always use genuine spare parts. Other types of
bolts could cause serious damage to the machine.
1. Stop the engine.
2. - Disconnect the starting cable from the spark plug.
3. Ensure all the rotating parts have stopped.
4. Remove the object that has fastened in the auger.
5. Lubricate the auger shaft (see above).
6. Align the holes in the shaft and the auger.
7. Remove the defective bolt parts.
6. Assemble the new genuine bolt.
8.9 ADJUSTMENT THE DRIVING BANDS
Valid for SNOW TRACK, see figur 27
If the machine is driven unevenly or if the driving bands slip,
these shall be checked/adjusted as follows:
1. Lift the band in the middle.
2. Measure the distance between the driving band and the
upper part of the support plate. The distance shall be 30
mm.
3. If necessary, adjust at the screw (3).
8.10 HEADLAMP BULB
Only 27 W original spare part bulb is allowed to be
used. Bulbs with higher power will damage the
headlamp.
The headlamp bulb is fitted to the headlamp by a bayonet
socket. See fig. 32. To replace the bulb proceed as follows:
1. Turn the bulb about 30° CCW and pull it out.
2. Release the plastic locks at each side of the bulb and pull
off the cable connection from the bulb.
3. Fit the new bulb in the reverse order.
