Lubricate the gear shaft with a good multi-purpose
light grease at least once a season or after every 25
hours of operation. Refer to Figure 16.
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 lubri-
cant. Avoid getting oil on rubber friction wheel and
aluminum drive plate. Refer to Figure 16.
GEAR CASE
The worm gear case has been filled with grease at
the factory. If disassembled for repairs, lubricate with
2 ounces of shell grease, part number 737-0168.
IMPORTANT:
Do not overfill the gear case. Dam-
age to the seals could result. Be sure the vent plug
is free of grease in order to relieve pressure.
ENGINE
Refer to separate engine manual for all engine main-
tenance procedures.
WARNING:
When following instruc-
tions in separate engine manual for
draining oil, be sure to protect frame to
avoid oil dripping onto transmission
parts.
CLEAN EQUIPMENT
Be certain to follow the precautions listed under TO
STOP ENGINE to prevent possible freeze-up.
SECTION 8: SERVICE
AUGERS
The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. See Figure 19. 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 710-0890A (shear
bolt) and 712-0429 (hex lock nut).
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.
To remove skid shoes, remove the four carriage
bolts, bell washers and hex nuts which attach them to
the snow thrower. Reassemble new skid shoes with
the four carriage bolts, bell washers (cupped side
goes against skid shoes) and hex nuts. Make certain
the skid shoes are adjusted to be level.
