Maintaining Your Snow Thrower, Engine, Augers

Maintaining

Your Snow

Thrower

WARNING

Always stop engine, disconnect spark plug, and ground against engine before performing any type of maintenance on your machine.

IMPORTANT

Avoid oil spillage on rub- ber friction wheel and aluminum drive plate.

IMPORTANT NEVER replace the auger shear pins with standard pins. Any damage to the auger gearbox or other components, as a result of doing so, will NOT be covered by your snow

Figure 6-1

Engine

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

Lubrication

Engine

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

Drive and Shifting Mechanism

At least once a season or after every 25 hours of opera- tion, remove rear cover. Lubricate all chains, sprockets, gears, bearings, shafts, and the shifting mechanism.

Use engine oil or a spray lubricant. Refer to Figure 6-1.

IMPORTANT: Keep all grease and oil off the rubber friction wheel and drive plate.

Shear Pin Vent Plug

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 6-2.

Grease fittings can also be found at either end of the auger shaft. Lubricate with a grease gun once a season. See Figure 6-2.

Gear Case

The auger gear case is equipped with a grease fitting. Lubricate with Shell Alvania lead-free grease once a season (order part number 737-0168). See Figure 6-2.

IMPORTANT: To relieve pressure, remove the vent plug before lubricating the gear case. See Figure 6-2. Failure to do so could result in damage to the gear case seals.

Augers

The augers are secured to the spiral shaft with shear pins and cotter pins. See Figure 6-2. If you hit a foreign object or ice jam, the snow thrower is designed so that the pins will shear.

1.If augers do not turn, check to see if pins have sheared.

2.Replace the pins if needed. Two replacement shear pins and cotter pins have been provided with the snow thrower. Spray an oil lubricant into shaft before inserting new pins and securing with new cotter pins.
