GEAR CASE

The gear case is lubricated with grease at the
any factory and
disassembled for any reason, lubricate with 2
ounces of Shell Alvania grease EPR00, part number
737-0168. Before reassembling, remove old sealant
and apply "Loctite 5699" or equivalent.
IMPORTANT:
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 28. If
you hit a 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-
0890 (shear bolt 5/16-18 x 1.5" long) and 712-0429
(hex insert lock nut 5/16-18 thread).
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
necessary.
To remove skid shoes, remove the four carriage
bolts, belleville washers and hex nuts which attach
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.
To remove shave plate, remove the carriage bolts,
belleville washers and hex nuts which attach it to
the snow thrower housing. Reassemble new shave
plate, making sure heads of the carriage bolts
are to the inside of the housing. Tighten securely.
