SECTION 9: LUBRICATION
(See Figure 13)
GEAR BOX
WARNING: Disconnect the spark plug
wire and ground against the engine before
performing any lubrication or maintenance.
The worm gear box has been filled with grease at
the factory. If disassembled for any reason, lubricate
with 1.5 ounces of Shell Alvania grease EPR00 (part
number 737-0168). Before reassembling, remove
old sealant and apply Loctite 5699 or equivalent.
WHEELS
Oil or spray lubricant into wheel bearings at least
once a season. Remove wheels, clean and coat
axles with a multi-purpose automotive grease.
WARNING: Do not overfill the gear box;
or damage to the seals could result. Be
sure the vent plug is free of grease in order
to relieve pressure.
CHUTE CRANK
The gear on the end of the chute crank should be
greased with multi-purpose automotive grease once
a season.
DRIVE AND SHIFTING MECHANISM
Lubricate at least once a season or after every 25
hours of operation. Remove rear cover. Lubricate
chains, sprockets, gears, bearings, shafts, and
shifting mechanism at least once a season. Use
engine oil or a spray lubricant. Avoid getting oil on
rubber friction wheel and aluminum drive plate.
AUGER SHAFT
Lubricate auger shaft at least once a season. Also
lubricate the auger bearings at least once a season.
Remove shear bolts on auger shaft. Oil or spray
lubricant inside shaft.
HEX SHAFT
ENGINE
Lubricate the hex shaft with Belray 6-in-1grease
(available at automotive stores, or order by part
number 737-0170) at least once a season or after
every 25 hours of operation. If for any reason, the
transmission was disassembled and the drive cable
disconnected, make sure, while reassembling, to
route the cable under the drive shaft and the axle
before reconnecting to the support bracket.
Important: Keep all grease and oil off of the rubber
friction wheel and aluminum drive plate.
Refer to engine manual for all engine lubrication
instructions.
WARNING: When following instructions in
separate engine manual for draining oil, be
sure to protect frame by avoiding oil
dripping into transmission parts.
