LUBRICATION SERVICES
Refer to the Engine Manual for lubrication
requirements on the engine powering your SNOW
THROWER. Your SNOW THROWER unit has five
(5)grease fittings, two (2) on the augers, one (1) in
the gearbox housing and two (2) on the auger shaft
bearings as shown in Figure 3.1. Service these and
the other general lube points as follows:
AUGER LUBRICATION: ONCE EACH YEAR,
preferably at the end of the winter season, remove
the two (2) shear bolts, apply grease to the fittings,
then spin the auger to work the grease out along the
auger shaft. Continue greasing and spinning augers
until grease appears at both ends of each auger
tube. Reinstall shear bolts and nuts after servicing.
This procedure will prevent the auger shaft from
rusting to the auger tube. Refer to FIG. 3.1.
BEARING LUBE: ONCE EACH YEAR, apply one
or two shots of grease from gun to the bearing
grease fittings located at the ends of the auger
shaft, just inside blower housings. Refer to FIG. 3.1.
GENERAL LUBE POINTS: ONCE EACH YEAR, or
more often if rust hampers operation, spread a light
coating of grease on the chute crank worm and on
the underside of the gear ring at the base of the
discharge chute. Squirt oil from the oil can into the
gap between the inside of the discharge chute and
the outside of the discharge flange of the blower
housing. Crank chute back and forth while oiling to
spread lubrication evenly over both surfaces.
Although not absolutely necessary, you may want to
remove each wheel at the end of the season and
apply a coating of grease on the axle shafts. This
will help to prevent rust and allow the wheels to be
moved more easily from transport to traction mode
during the next season.
GEARBOX LUBRICATION: Grease the gearbox ONCE
EACH YEAR, or more often as required, with 5 shots of
SNAPPER "OO" grease. Refer to FiG. 3.1. "00" grease
is available from your SNAPPER Dealer in handy
squeeze containers.
CHUTE CRANK SERVICE (1422/1522/1722)
If the chute does not crank easily after being lubricated
as specified in the foregoing GENERAL LUB POINTS
sectbn, loosen the mounting nut and bolt on the crank
worm bracket as shown in Figure 3.2 and then pivot the
bracket slightly away
from
or toward the gear ring until
the chute cranks with minimum effort. Retighten the bolt
and nut after adjusting is completed.
CHUTE CRANK SERVICE (1524/1724)
If the chute does not crank easily after lubricating, as
specified under GENERAL LUB POINTS, loosen
both
adjusting nuts on the outside of the crank worm bracket
as shown in Figure 3.3 and pivot the bracket slightly
away from or toward the gear ring until the chute cranks
with minimum effort. Retighten the
inside
nut first, then
jam the
outside
nut tight against the inside nut to lock at
the new setting.
