If also replacing the drive belt, proceed to the “Drive 

11. 

Belt” instruction. If not, reposition the transmission 

frame back onto the auger housing. Install the drive 

belt on the engine pulley, re-connect the auger cable 

“Z” fitting and auger idler rod ferrule to the brake 

bracket. Reposition and secure the engine pulley belt 

guard, and re-install the belt cover. 

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 and 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.  

Pull the idler pulley away from the backside of the drive 

1. 

belt to relieve the tension and slip the drive belt off the 

idler pulley.  Carefully release the idler pulley. See Figure 

7-8.

Roll the drive belt off the lower drive pulley and then 

2. 

remove the belt from the engine pulley.

Install the new belt on the pulleys in the reverse order and 

3. 

re-tension with the idler pulley.
Reassemble by performing the previous steps in the 

4. 

opposite order and manner of removal.

Changing Friction Wheel

The rubber on the friction wheel is subject to wear and 

should be checked periodically. Replace the friction wheel 

if any signs of wear or cracking are found.

Drain the gasoline from the snow thrower, or run the 

1. 

fuel tank dry to prevent a hazardous situation.
Tip the snow thrower up and forward, so that it rests on 

2. 

the housing.
Remove screws from the frame cover underneath the 

3. 

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

wheels from the axle.

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

4. 

hex screw and belleville washer and bearing from left 

side of the frame. Refer to Figure 7-10.
