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 10.

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.

Gear Case

The gear case is lubricated with grease at the factory and it does not require checking. If disassembled for any reason, lubricate with 2 ounces of Shell Alvania grease EPR00, part number 737-0168. Before reassembling, remove old sealant and apply new sealant. See Figure 14.

To check the level of grease in the gear case, remove the vent plug. 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.

Traction Control / Auger Control Lock

The cams on the ends of the control rods which interlock the traction drive and auger drive controls must be lubricated at least once a season or every 25 hours of operation. The cams can be accessed beneath the handle panel. Use a multi-purpose automotive grease. See Figure 13.

Grease fittings can be found at either end of the auger shaft. Lubricate with a grease gun once a season. See Figure 14.

Auger Bearings

Every season lubricate the auger bearings and the bearings on the side of the frame with light oil. See Figure 14.

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 10.

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 a season.
