• The warranty on this snow thrower does not cover
items that have been subjected to operator abuse
or negligence. To receive full value from warranty,
operator must maintain the snow thrower as
instructed here.
Engine
Refer to the separate Tecumseh Engines manual
packed with your unit for all engine maintenance.
Lubrication
Engine
Refer to the engine manual packed with your unit for all
engine maintenance and lubrication instructions.
Drive and Shifting Mechanism
At least once a season or after every 25 hours of
operation, remove the lower frame cover. Lubricate all
chains, sprockets, shafts, and bearings. Use engine oil
or a spray lubricant.
IMPORTANT
: Keep all grease and oil off the rubber
friction wheel and drive plate.
Hex Gear Shaft:
Once a season, lubricate the hex
shaft with a penetrating oil, but not grease.
Gear Case
:
The gear case is lubricated with grease
at the factory and does not require regular lubrication. If
disassembled for any reason, lubricate with two ounces
of grease (part # 737-0168). Before reassembling,
remove old sealant and apply new sealant.
Do not
overfill the gear case.
Wheels
At least once a season, remove both wheels. Clean and
coat the axles with a multipurpose automotive grease
before reinstalling wheels.
Chute Directional Control
Once a season, the spiral end on the chute directional
control should be greased with multipurpose automotive
grease.
Auger Shaft
At least once a season, remove the shear pins from the
auger shaft and spray lubricant between the auger shaft
and the auger hubs and spacers. Also lubricate the flange
bearings found at either end of the shaft. See Figure 6-1.
Grease fittings are provided in the bearing housings at
each end of the auger shaft. Lubricate the bearings with a
grease gun once a season. See Figure 6-1.
Gear Case
The auger gear case is equipped with a grease fitting.
Lubricate with Shell Alvania lead-free grease once a
season (order part number 737-0168). See Figure 6-1.
IMPORTANT
: Do not overfill the gear case. Damage to
the seals could result. Be sure the vent plug is free of
grease in order to relieve pressure. See Figure 6-1
Augers
The augers are secured to the spiral shaft with shear pins
and cotter pins. See Figure 6-1. If you hit a foreign object
or ice jam, the pins are designed to shear. The shear pins
are installed to protect the gear box from damage. Do not
use substitute pins or bolts.
1. If augers do not turn, check to see if pins have
sheared.
2. Replace the pins if needed. Two replacement shear
pins and cotter pins have been provided with the
snow thrower. Spray an oil lubricant into shaft before
inserting new pins and securing with new cotter pins.
