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

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.
