Section III - MAINTENANCE
LUBRICATION SERVICES
Refer to the Engine Owner,s Manual for lubrication
requirements on the engine powering your Snow
Thrower. Your Snow Thrower Unit (Model 17243 Only)
has (4) grease fittings, two (2) on the augers, 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: ONE 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 Figure 3.1.
BEARING LUBE: On 17243 Models, 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 (On 14223,16223 Models, bearings
are self-lubricating). Refer to Figure 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 prevent rust and allow the wheels to be
removed more easily..
GEARBOX LUBRICATION: Check Grease EACH
YEAR. To add grease, remove check plug and pump
BENALENE 900™ Grease (Part No. 2-9577) into
grease fitting on case until grease is visible from
check hole. Reinstall check plug.
If a squeeze tube of BENALENE 900™(Part No. 2-9577)
is used, unscrew grease plug and apply through hole
until grease is visible from check hole. Reinstall fill plug
and check plug. Refer to Figure 3.1.
CHUTE CRANK SERVICE (14223 & 16223)
If the chute does not crank easily after lubricating,
loosen the adjustment bolt on the outside of crank worm
bracket as shown in Figure 3.2.
Move the bracket
slightly away from the chute gear ring or in toward the
ring until the chute cranks easily (the ring gear teeth
should be in full contact with the worm after adjustment).
FIGURE 3.2
CHUTE CRANK SERVICE (17243)
If the chute does not crank easily after lubricating,
loosen the adjustment bolt on the outside of crank worm
bracket as shown in Figure 3.3.
Move the bracket
slightly away from the chute gear ring or in toward the
ring until the chute cranks easily (the ring gear teeth
should be in full contact with the worm after adjustment).
Tighten adjustment bolt.
