them to the snow thrower. Reassemble new skid
shoes with the four carriage bolts, belleville washers
(cupped side goes against skid shoes) and hex nuts.
Make certain the skid shoes are adjusted to the
same level on both sides.

rubber friction wheel and aluminum drive plate.
WARNING: Disconnect the spark plug
wire from the spark plug and ground.
DRIVE AND SHIFTING MECHANISM
At least once a season or after every 25 hours of
operation, remove the bottom frame 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
rubber friction wheel and aluminum drive plate.
AUGER BELTS
NOTE: It is necessary to remove both belts in
order to change either one. If changing just one belt,
be certain to check the condition of the other belt.
GEAR CASE
1. Remove the plastic belt cover on the front of the
engine by removing the two self-tapping screws.
See Figure 28.
The gear case is lubricated with grease at the
factory and does not require checking. If
disassembled for any reason, lubricate with 2
ounces of shell grease, part number 737-0168.
2. Drain the gasoline from the snow thrower, or
place a piece of plastic under the gas cap.
3.
Tip the snow thrower up and forward so that it
rests on the auger housing.
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
AUGERS
The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. Refer to Figure 27. If
you hit a hard foreign object or ice jam, the snow
thrower is designed so that the hex bolts will shear.
If the augers will not turn, check to see if the bolts
have sheared. Two replacement shear bolts and hex
lock nuts have been provided with the snow thrower.
For future use, order part number 710-0890A (shear
bolt 5/16-18 x 1.5" long) and 712-0429 (hex insert
lock nut 5/16-18 thread).
