SERVICE AND MAINTENANCE

threads of the input shaft. Torque the hex screw to 250-325 in. /lbs. to secure the auger pulley assembly on the input shaft.

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

IMPORTANT: Repeat the “Auger Drive Control Test” from the As- sembly section before operating 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” instruc- tions in the previous sub-section.

1.a. Pull the idler pulley away from the backside of the drive belt to relieve the tension. See Figure 30.

b.Slip the drive belt off the idler pulley. Carefully release the idler pulley.

2.Roll the drive belt off the lower drive pulley.

3.Remove the belt from the engine pulley.

4.Install the new belt on the pulleys in the reverse order and re-tension with the idler pulley.

5.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 periodically. Replace the friction wheel if any signs of wear or cracking are found.

1.Run the unit’s fuel tank dry before performing Step 2.

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 31). Remove the right wheel from the axle.
