SECTION 6: MAINTAINING AND SERVICING YOUR SNOW THROWER

WARNING: Before lubricating, repairing, or inspecting, disengage all controls and stop engine. Wait until all moving parts have come to a complete stop. Always wear safety glasses during operation or while performing any adjustments or repairs.

Engine

Refer to the separate Tecumseh Engines manual packed with your unit for all engine maintenance.

Lubrication

Engine

Refer to the separate Tecumseh Engines manual packed with your unit for all engine lubrication instructions.

Gear Shaft

The gear (hex) shaft should be lubricated at least once a season or after every 25 hours of operation.

Remove the lower frame cover by removing the two screws which secure it.

Apply a light coating of an all-weather multi- purpose grease to the hex shaft. See Figure 8.

Figure 8

IMPORTANT: Keep lubricant off the friction wheel and drive plate.

Wheels

At least once a season, remove both wheels. Clean and coat the axles with a multipurpose automotive grease before reinstalling wheels.

Chute Directional Control

Once a season, the spiral end on the chute directional control should be greased with multipurpose automotive grease.

Auger Shaft

At least once a season, remove the shear pins on auger shaft. Spray lubricant inside shaft, around the spacers. Also lubricate the flange bearings found at either end of the shaft. See Figure 9.

Gear Case

The auger gear case has been filled with grease at the factory. If disassembled for any reason, lubricate with two ounces of grease (Part Number 737-0168).

IMPORTANT: Do not overfill the gear case. Damage to the seals could result. Be sure the vent plug is free of grease in order to relieve pressure.

WARNING: Before servicing, repairing, or inspecting, disengage all controls and stop engine. Wait until all moving parts have come to a complete stop.

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 and hex flange nuts which secure them to the snow thrower. Reassemble new skid shoes with the four carriage bolts (two on each side) and hex flange nuts. Refer to Figure 6.

To remove shave plate, remove the carriage bolts and hex nuts which attach it to the snow thrower housing. Reassemble new shave plate, making sure heads of carriage bolts are to the inside of housing. Tighten securely.
