To check the level of grease in the gear case, remove the vent plug. If your unit is equipped with a grease fitting, you may, if necessary, add grease using a grease gun and the grease fitting on the side of the gear case.

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

Auger Shaft

•At least once a season, remove the shear pins from the auger shaft and spray lubricant inside the shaft. See Figure 15.

•On certain models, grease fittings can be found at either end of the auger shaft. Lubricate with a grease gun once a season.

Auger Bearings

Every season lubricate the auger bearings and the bearings on the side of the frame with light oil. See Figure 15.

Drive and Shifting Mechanism

Lubricate at least once a season or after every 25 hours of operation. Remove the rear cover, lubricate any chains, sprockets, gears, bearings, shafts, and shifting mechanism at least once a season. Use engine oil or a spray lubricant. Avoid getting oil on the friction wheel rubber and aluminum drive plate. Refer to Figure 11.

There is a grease fitting on the top of the axle shaft which drives the rear track drive wheels on both sides of the unit. Grease these fittings every 25 hours or once

aseason.

Gear Shaft

Lubricate the gear shaft with 6-n-1 grease at least once a season or after every 25 hours of operation (available at automotive stores, or order part number 737-0170).

Refer to Figure 11.

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

Chute Directional Control

The worm gear on the chute directional control should be greased with multipurpose automotive grease.

SECTION 7: SERVICING YOUR SNOW THROWER

WARNING: Before servicing, repairing, or inspecting, disengage all controls 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. Always wear safety glasses during operation or while performing any adjustments or repairs.

Augers

•The augers are secured to the spiral shaft with shear pins and bow tie cotter pins. If you hit a hard foreign object or ice jam, the snow thrower is designed so that the pins may shear. Refer to Figure 17.

•If the augers will not turn, check to see if the pins have sheared. 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 pins. 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. They should be checked periodically and replaced when necessary.
