NOTE: Make sure to remove the piece of wood blocking the impeller.

Check the auger drive belt adjustment. With the auger clutch lever in the disengaged position, the top surface of the new belt should be even with the outside diameter of the pulley.

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.

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 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.

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.Drain the gasoline from the snow thrower.

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.

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.
