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.

Engine

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

Lubrication

Engine

Refer to the separate engine manual packed with your unit.

Gear Shaft

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

the spacers. Also lubricate the flange bearings found at either end of the shaft. See Figure 21.

Shear Pins

Shear Pins

•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 20.

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

Wheels

Oil or spray lubricant into bearings at wheels at least once a season. Remove wheels, clean and coat axles with a multi-purpose automotive grease.

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

Augers

The augers are secured to the spiral shaft with shear pins and cotter pins. See Figure 21. If you hit a foreign object or ice jam, the snowthrower is designed so that the shear pins will shear.

If the augers will not turn, check to see if the shear pins have sheared. Replacements have been provided with the snowthrower. When replacing pins, spray an oil lubricant into shaft before ireassembling.

IMPORTANT:NEVER replace the auger shear pins with anything other than OEM Part No.738-04124 replacement shear pins. Any damage to the auger gearbox or other components as a result of failing to do so will NOT be covered by your snow thrower’s warranty.

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.
