Drive and Shifting Mechanism

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

Gear Shaft

Lubricate the gear shaft with 6-in-1 grease (part number 737-0170) at least once a season, or after every 25 hours of operation. Refer to Figure 11.

IMPORTANT: Be careful not to allow grease to get on the drive plate or friction wheel.

Traction Control / Auger Control Lock

The cams on the ends of the control rods which interlock the traction drive and auger drive clutches must be lubricated at least once a season or every 25 hours of operation using a multi-purpose automotive grease. The cams can be accessed beneath the handle panel. See Figure 16.

Bonded Friction Wheel

Follow the instructions below to check the condition of the bonded friction wheel every 25 hours of operation.

•Remove the six self-tapping screws from the frame cover underneath the snow thrower.

•Visually inspect the bonded friction wheel for excessive wear, cracks, or loose fit on the friction wheel drive hub.

•Also engage the traction control and check if the friction wheel is making contact with the friction plate. Refer to Figure 11.

•If it does not make contact, adjust the traction drive cable and recheck the friction wheel.

•Replace bonded friction wheel if necessary. Refer to instructions in Service Section on Page 17.
