Changing Friction Wheel

The rubber on the friction wheel is subject to wear and should

be checked after the first 25 hours of operation, and periodically

thereafter. Replace the friction wheel if any signs of wear or

cracking are found.

1. Run the fuel tank empty.

2. Tip the snow thrower up and forward, so that it rests on the

housing.

3. Remove screws from the frame cover underneath the snow

thrower (refer to Figure 7-9). Remove the right wheel from

the axle.

Figure 7-9

4. Using a 3/4” wrench, hold the hex shaft and remove the

hex screw and belleville washer and bearing from left side

of the frame. Refer to Figure 7-10.

NOTE: To adjust, disconnect ferrule from brake bracket

assembly. Thread ferrule in (towards idler) to increase

tension on belt, or out to decrease belt tension.

NOTE: The brake puck must always be firmly seated in the

pulley groove when auger control is disengaged.

CAUTION: Repeat the “Testing Auger Drive Control”

from the Assembly & Set-up section before operating

the snow thrower.

14. Re-install the belt cover.

Drive Belt Replacement

If not already done, remove the auger drive belt from the

front pulley of the engine double pulley. Refer to “Auger Belt

Replacement” instructions in the previous sub-section.

1. Use a wrench to rotate the idler pulley away from the backside

of the drive belt and pivot the belt keeper up (Figure 7-3) to

relieve the tension and slip the drive belt off the idler pulley.

Carefully release the idler pulley. See Figure 7-8.

2. Roll the drive belt off the lower drive pulley and then remove

the belt from the engine pulley.

3. Install the new belt on the engine pulley, then seat around the

lower drive pulley and re-tension with the idler pulley.

4. Reassemble by performing the previous steps in the

opposite order and manner of removal.
