Bolens 933 SWE Snow Blower User Manual


 
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. See Figure 6-3.
Grease fittings can also be found at each end of the auger
shaft. Lubricate 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 four 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 Cable
If the full range of speeds (forward and reverse) cannot be
achieved, refer to the Figure 6-4 and adjust the shift cable
as follows:
Place the shift lever in the fastest forward speed
position.
Loosen the hex nut on the shift cable index bracket.
See Fig. 6-4.
Pivot the bracket downward to take up slack in the
cable.
Retighten the hex nut.
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. See Figure 6-5.
Retighten the nuts.
