1. Chute crank should be located in the center of the hole in the console, adjust as required.

2. Loosen adjusting bracket (B) hardware.

3. Move bracket up and down as needed.

4. Tighten hardware.

5. If more adjustment is needed, loosen the four handlebar attaching bolts (E). Reposition handlebars a little to center hole around the chute crank. Tighten hardware.

Adjust discharge chute crank - tightness:


M86561b

1. Operate chute crank. Crank should be tight enough so it will not move from engine vibration, but it should be loose enough to operate smoothly.

2. If chute crank is too loose, tighten nut (F).

3. If chute crank is too tight, loosen nut (F).

Install and Adjust Auger Brake / Drive Cable


M86580

1. Connect auger brake / drive cable spring end (A) to tab on frame.

2. Position both nuts (B) midrange on the cable adjusting threads.

3. Connect cable to the brake / drive lever (C) and tighten both nuts.

Adjust Auger Brake / Drive Cable


M86565

1. Remove two cap screws (A) to remove belt cover (B).


M86566

2. Check clearance between brake pad (C) and auger drive belt (D):

ˇ With auger drive lever released, the brake pad (C) must contact auger drive belt (D).

NOTE: When the auger drive cable has some slack in it; that means maximum spring force is being applied to the brake arm (E).


M86580

3. Check auger drive cable (F), cable should have some slack in it. If cable is tight or very loose, change cable length by adjusting nuts (G).

Adjust Auger Drive Belt Tension

c CAUTION: Avoid injury! It is necessary to perform this adjustment with the belt cover removed, and extreme care is to be taken to prevent injury. Stand well clear of the open belt drive while engine is running.


M86563

1. Start engine and run at full throttle.

2. Slowly depress the auger drive lever (A) until the auger shaft begins to rotate. At this point the auger drive lever should be between 76 to 83 mm (3 to 3-1/4 in.) (B) from the handle grip.

3. If your dimension is not within this range, shut off the engine and adjust the auger drive belt tension as required.

NOTE: A 1.5 mm (1/16 in.) adjustment of the pulley will result in an approximate 6 mm (1/4 in.) change in the measurement (B).


M86566

4. To adjust the belt tension, loosen the idler arm pulley lock nut (C) and move the pulley (D) to loosen or tighten the belt tension.

5. Tighten lock nut (C).

6. Repeat steps 1through 5 until adjusted properly.

7. Install belt cover.

Install And Adjust Speed Selector Linkage

c CAUTION: Avoid injury! Help prevent fuel spillage. Before tipping unit up onto housing, remove enough fuel so that no spillage will occur.


M94193
