Chute Directional Control

Once a season, lubricate the eye-bolt bushing and the spiral with 3-in-1 oil.

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. SeeFigure 6-3.

Gear Case

The auger gear case is equipped with a grease fitting. Lubricate with 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 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 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:

1.Place the shift lever in the fastest forward speed position.

2.Loosen the hex nut on the shift cable index bracket. See

Figure 6-1.

3.Pivot the bracket downward to take up slack in the cable.

4.Retighten the hex nut.

Figure 6-17

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. See Figure 6-5.

2.Retighten the nuts.
