Auger Shaft
At least once a season, one at a time, remove the shear
pins from the auger shaft. Spray lubricant inside the hub
of each auger spiral assembly and around the spacers on
the auger shaft.
Grease fittings can also be found at each end of the auger
shaft. Lubricate flange bearings found at each end of the
shaft with a grease gun once a season. See Figure 6-3.
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 6-3.
NOTE: To relieve pressure, remove the vent plug before
lubricating the gear case. See Figure 6-3. Failure to do so
could result in damage to the gear case seals.
Augers
Each of the six auger spiral assemblies is secured to the
spiral shaft with a shear pin and cotter pin. If the auger
should strike a foreign object or ice jam, the snow thrower
is designed so that the pins may shear.
If augers do not turn, check to see if pins have
sheared.
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.

Adjustments
Shift Rod
If the full range of speeds (forward and reverse) cannot be
achieved, refer to the figure to Figure 6-4 and adjust the
shift rod as follows:
1. Looking underneath the handle panel, note which of
the three holes in the shift lever the ferrule is inserted
into. Also note the direction of insertion. Then remove
the internal cotter pin and flat washer from the ferrule
and withdraw the ferrule from the shift lever. See Figure
6-4.
2. Place shift lever in sixth (6) position or fastest forward
speed.
3. Push shift rod and shift arm assembly down sharply as
far as it will go to shift the drive into the fastest forward
position.
4. As necessary, rotate the ferrule up or down the shift rod
until the ferrule lines up with the hole from which it was
earlier removed. See Figure 6-4.
5. From the direction noted earlier, insert the ferrule into
the proper hole. Reinstall the washer and secure with the
internal cotter pin.
Chute Bracket Adjustment
If the spiral at the bottom of the chute directional control
is not fully engaging with the chute assembly, the chute
bracket can be adjusted. To do so:
Loosen the two nuts which secure the chute bracket
and reposition it slightly. Refer to Figure 6-5.
Retighten the nuts.
