IMPORTANT: Keep all grease and oil off of the friction wheel and drive plate.
DRIVE AND SHIFTING MECHANISM
Remove rear cover. Oil 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 rubber friction wheel and aluminum drive plate.
GEAR CASE
The worm gear case has been filled with grease at the factory. If disassembled for any reason, lubricate with 2 ounces of Shell Alvania grease EPR00, part number
IMPORTANT: Do not overfill the gear case. Damage to the seals could result. Be sure the vent plug is free of grease in order to relieve pressure.
SECTION 10: MAINTENANCE
WARNING: Disconnect the spark plug wire and ground against the engine before performing any repairs or maintenance.
ENGINE
Refer to separate engine manual for all engine maintenance procedures.
AUGERS
The augers are secured to the spiral shaft with two shear bolts and hex lock nuts. See Figure 24. If you hit a foreign object or ice jam, the snow thrower is designed so that the bolts will shear.
If the augers will not turn, check to see if the bolts have sheared. A replacement shear bolt (P) and hex lock nut (Q) have been provided with the snow thrower. When replacing bolts, spray an oil lubricant into shaft before inserting new bolts.
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.
