Lubrication
Drive and Shifting Mechanism
• At least once a season or after every 25 hours of
operation, remove rear cover. Lubricate any chains,
sprockets, gears, bearings, shafts, and the shifting
mechanism at least once a season. Use engine oil
or a spray lubricant. Refer to Figure 11.
IMPORTANT: Avoid spillage of oil on rubber friction
wheel and aluminum drive plate.
Gear Shaft
• Lubricate the gear shaft with 6-in-1 grease (part
number 737-0170) at least once a season, or after
every 25 hours of operation.
Refer to Figure 11.
IMPORTANT: Keep all grease and oil off the rubber
friction wheel and drive plate.
Gear Case
The gear case is lubricated with grease at the factory
and it does not require checking.
• If disassembled for any reason, lubricate with 2
ounces of Shell Alvania grease EPR00, part
number 737-0168. Before reassembling, remove
old sealant and apply new sealant.
IMPORTANT: Do not overfill the gear case, since
damage to the seals could result. Be sure the vent plug
is free of grease in order to relieve pressure.
Auger Shaft
• At least once a season, remove the shear bolts
from the auger shaft and spray lubricant inside the
shaft. See Figure 13.
Figure 13
Engine
Refer to the engine manual for instructions.
Discharge Chute
The base of the discharge chute and the spirals on the
chute crank should be lubricated at least every 25
hours of use. Apply the lubricant under the base of the
chute and where the spirals contact the discharge
chute. See Figure 14.
Figure 14
Auger Bearings and Shaft
• Every season lubricate the auger bearings and the
bearings on the side of the frame with light oil. See
to Figure 13.
• Use oil or spray lubricant into the bearings at the
wheels at least once a season. Remove the
wheels, one side at a time, and clean and coat
axles with multi-purpose automotive grease.
• Lubricate the auger shaft at least once a season.
To do this:
• Remove the shear bolts on the auger shaft.
• Oil or spray lubricant inside shaft.
• Carefully spin the auger around by hand to
disperse the lubricant.
• Reinstall the shear bolts.
Traction Control / Auger Control Lock
The cams on the ends of the control rods which
interlock the traction drive and auger drive clutches
must be lubricated at least once a season or every 25
hours of operation using a multi-purpose automotive
grease. The cams can be accessed beneath the handle
panel. See Figure 15.
