SECTION 7: SERVICE

WARNING: Before servicing, repairing, or

Augers

The augers are secured to the spiral shaft with two shear bolts and hex lock nuts. If the snow thrower hits a foreign object or ice jam, hex bolts will shear.

• If the augers will not turn, check to see if the bolts have sheared. Two replacement shear bolts and hex lock nuts have been provided in the snow thrower’s hardware pack. For future use, order part number 710-0890A (shear bolt 5/16-18 x 1.5") and 712-0429 (hex lock nut 5/16-18).

Shave Plate and Skid Shoes

The shave plate and skid shoes on the bottom of the snow thrower are subject to wear. They should be checked periodically and replaced when necessary.

• To remove skid shoes, remove the four carriage bolts, bell washers and hex nuts which attach them to the snow thrower. Reassemble new skid shoes with the four carriage bolts, bell washers (cupped side goes against skid shoes) and hex nuts. Make certain the skid shoes are adjusted to be level.

• To remove shave plate, remove carriage bolts, bell washers and hex nuts which attach it to the snow thrower housing.

• Reassemble new shave plate, making sure heads of the carriage bolts are to the inside of the housing. Tighten securely.

Belt Replacement

WARNING: Disconnect the spark plug wire

from the spark plug and ground.

Auger Belts

NOTE: It is necessary to remove both auger belts in order to change either one. If changing just one belt, be certain to check the condition of the other belt.

• Remove the plastic belt cover on the front of the engine by removing the two self-tapping screws. See Figure 13.

• Drain the gasoline from the snow thrower, or place a piece of plastic under the gas cap.

• Tip the snow thrower up and forward so that it rests on the housing.
