Yard-Man OGST-2806 manual Servicing Your Snow Thrower, Augers, Shave Plate and Skid Shoes

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 pins and cotter pins. If you hit a foreign object or ice jam, the snow thrower is designed so that the pins may shear. Refer to Figure 16.

If the augers do not turn, check if the pins have sheared. Two replacement shear pins and cotter pins have been provided with the snow thrower. When replacing pins, spray an oil lubricant into shaft before inserting new pins.

IMPORTANT: NEVER replace the auger shear pins 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.

Shave Plate and Skid Shoes

The shave plate and skid shoes on the bottom of the snow thrower are subject to wear. These 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 and hex flange locknuts which attach two skid shoes to the snow thrower on two sides. See Figure 15.

•Reassemble new skid shoes with the hardware removed earlier . Make certain the skid shoes are adjusted to be level.

•To remove the shave plate, remove the carriage bolts and hex flange locknuts which attach shave plate to the snow thrower housing.See Figure 19.

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

Replacing Belts

•Remove the plastic belt cover, located near the engine, by removing the three self-tapping screws and flat washers that secure it. See Figure 19.
