Wheels

•Oil or spray lubricant into bearings at wheels at least once a season. Pull klick pin, remove wheels, clean and coat axles with a multipurpose automotive grease. See Figure 23.

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 24 .

part number 737-0168. Before reassembling, remove old sealant and apply new sealant.

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.

Check V-Belts

Follow instrcutions below to check the condition of the drive belts every 50 hours of operation.

•Remove the plastic belt cover on the front of the engine by removing two self-tapping screws.

•Visually inspect for frayed, cracked, or excessively worn out belts.

Check Friction Wheel

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

• Remove the six self-tapping screws from the frame

cover underneath the snow thrower.

• Visually inspect the friction wheel rubber 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 friction plate. If

it does not make contact, adjust the traction drive

cable and recheck the friction wheel.

• Replace friction wheel rubber if necessary. Refer to

instructions on page 23.

• After maintenance on friction wheel is over, re-

attach the frame cover to the snow thrower with the

hardware removed earlier.

Engine Maintenance

Engine Oil

Only use high quality detergent oil rated with API service classification SF, SG or SH. Select the oil’s SAE viscosity grade according to the expected

Figure 24

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.

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

Gear Case

The gear case is lubricated with grease at the factory and does not require further lubrication regularly.

•However, if disassembled for any reason, lubricate with 2 ounces of Shell Alvania™ grease EPR00,

Viscosity Chart

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, these multi- viscosity oils will result in increased oil consumption when used above 32oF. Check your snow thrower’s engine oil level more frequently to avoid possible engine damage from running low on oil.
