Lubrication
1. Drive Mechanism: Once a season or after every
25 hours of operation, remove rear frame cover and
lubricate any chains, sprockets, gears, bearings, and
shafts with engine oil or lubricant spray.
2. Hex Gear Shaft: Once a season, lubricate the hex
shaft with a penetrating oil, but not grease.
3. Gear Case: The gear case is lubricated with grease
at the factory and does not require regular lubrication.
However, if disassembled for any reason, lubricate
with 2 ounces of Shell Alvania™ grease (part #
737-0168). Before reassembling, remove old sealant
and apply new sealant.
4. Wheels: Once a season, remove the bolt from
each wheel and take the wheel off the axle. Apply a
multipurpose automotive grease on the shaft before
putting back the wheels.
5. Auger Shaft: At least once a season, remove the
shear pins on auger shaft. Spray lubricant inside shaft,
around the spacers. Also lubricate the flange bearings
found at either end of the shaft. See Figure 18.
6. Drive/Auger Control Lock: The cam on the ends of
the control rods which interlock the drive and auger
controls must be lubricated at least once a season
or every 25 hours of operation using a multi-purpose
automotive grease. The cam can be accessed
beneath handle panel.
7. Engine: Refer to the separate Tecumseh Engine
manual packed with your unit for all engine lubrication
instructions.
Augers
The augers are secured to the spiral shaft with two shear
pins and cotter pins. See Figure 19. If you hit a foreign
object or ice jam, the snow thrower is designed so that
the pins will shear.
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.
See Figure 19.
