Troy-Bilt 13045 Servicing Your Snow Thrower, Augers, Shave Plate and Skid Shoes, Replacing Belts

SECTION 7: SERVICING YOUR SNOW THROWER

WARNING: Before servicing, repairing, or inspecting, disengage all clutch levers and stop engine. Wait until all moving parts have come to a complete stop. Disconnect spark plug wire and ground it against the engine to prevent unintended starting.

Augers

The augers are secured to the spiral shaft with two shear bolts and hex lock nuts. If you hit a foreign object or ice jam, the snow thrower is designed so that the bolts may shear. See Figure 17.

If the augers do not turn, check if the bolts have sheared. Two replacement shear bolts and hex lock nuts have been provided with the snow thrower. Refer to Hardware Pack on page 5.

IMPORTANT: NEVER replace the auger shear bolts with standard hex bolts. Any damage to the auger gearbox or other components, as a result of doing so, will NOT be covered by your snow thrower’s warranty.

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

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.

NOTE: The skid shoes on this machine have two wear edges. When one side wears out, they can be rotated 180° to use the other edge.

•Remove the six carriage bolts (three per side), bell washers and hex nuts which secure the skid shoes to the snow thrower on either side. See Figure 13.

•Reassemble new skid shoes with the hardware removed earlier (cupped side of bell washer against the skid shoes). Make certain the skid shoes are adjusted to be level. Refer to Figure 13.

•To remove the shave plate, remove the carriage bolts, bell washers and hex nuts which secure the shave plate to the snow thrower housing. See Figure 17.
