Gear Case

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.

The auger gear case is equipped with a grease fitting. Lubricate with Shell Alvania lead-free grease (737-0168) once a season. 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.

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.

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.Lookingunderneaththehandlepanel,notewhichofthethree 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

Figure 6-4

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.Fromthedirectionnotedearlier,inserttheferruleintotheproper 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:

1.Loosen the two nuts which secure the chute bracket and reposition it slightly. Refer to Figure 6-5.

2.Retighten the nuts.
