Screws G A E F D Gear Bracket Adjustment If the discharge chute becomes difficult to rotate or begins to operate erratically, the chute direction control rod gears may require adjustment: 1. Loosen the gear bracket mounting nuts (Figure 21). 2. Slide the gear bracket into the position that provides the best engagement between the gears. 3. Tighten the bracket mounting hardware, and check for smooth operation. 4. Readjust if necessary. 5. Lubricate the chute direction control rod gears with a medium weight (10W) oil ELECTRIC DISCHARGE CHUTE ROTATOR MOTOR ADJUSTMENT If the electric chute rotator does not function properly, check the electrical connections and then perform the procedure below. 1. Remove the rotator motor cover. 2. Lubricate the chute ring gear. 3. Loosen the screws (A, Figure 22) securing the rotator motor and adjust so that the motor gear and chute ring gear mesh. Tighten the capscrews. 4. Reinstall the rotator motor cover. A A Adjustments & Service 25 EASY TURN™ CABLE ADJUSTMENT If the Easy Turn™ cable has stretched, the gears will not disengage when the control lever is activated. Adjust the cable using the following procedure. 1. Turn the engine off and disconnect the spark plug wire. 2. Loosen the jam nut (B, Figure 23). 3. Turn the adjustment nut (A) to lengthen or shorten the cable. The cable should be tightened just until all slack is removed from the lever, however it must not engage the Easy Turn™ release without depressing the control lever. 4. Tighten the jam nut.

Cotter Pins SHEAR PIN REPLACEMENT Under most circumstances, if the auger strikes an object which could cause damage to the unit, the shear pin will break. (This protects the gear box and other parts from damage.) The shear pins are located on the auger shaft as shown in Figure 24. To replace the shear pins, tap out the broken pin with a pin punch, and install a new shear pin and cotter pin. Spread the legs of the new cotter pin fully. Do NOT replace shear pins with anything other than the correct grade replacement shear pin. (Use of bolts, screws or a harder shear pin will lead to damaged equipment.) WARNING Do not go near the discharge chute or auger when the engine is running. Do not run the engine with any cover or guard removed. A B A B Adjustments & Service 26 BELT REPLACEMENT 1. Turn off the engine, remove the spark plug wire, and wait for all moving parts to stop. Rotate the spout full right. Loosen the two screws (B, Figure 25) securing the belt cover. 2. Tilt the cover forward and work it off the snowthrower. 3. Move the belt guides (B, Figure 26) by loosening the two capscrews (A). 4. Remove the auger drive belt as follows: a. Slip the auger drive belt (D, Figure 26) from the idler pulley by pushing it away from the pulley and then toward the rear. b. Remove the belt from the engine pulley. Slip the belt from under the brake pad. c. Remove two capscrews from bottom cover to snowthrower frame. Loosen nuts (A, Figure 27) on each side to release auger pulley belt stops (B). Move belt stops and remove belt from pulley (C). d. Remove the two bolts (D, Figure 27) from the gear assembly. e. Loosen the set collar and slide the axle shaft right. f. Belt can be removed from top or bottom. For more clearance to remove the belt, engage the traction drive lever. 5. Remove the traction drive belt as follows: a. Pull the idler pulley (I, Figure 26) away from the belt and slip the belt from the pulley. b. Slip the belt off the traction pulley and then the engine pulley. The arm for the front idler pulley (G, Figure 26) may have to be pivoted to provide clearance for removing the belt from the traction pulley. c. Pull the belt out between the auger pulley (F, Figure 26) and traction pulley. Figure 26. Belts and Pulleys A. Capscrews B. Belt Guides C. Traction Drive Belt D. Auger Drive Belt E. Engine Pulley F.

Reverse the procedure to install the belts. Be sure there are no twists and the belts are properly seated in the grooves. Adjust the belt stops so there is 1/8” (3mm) clearance between belt and stop. The pattern for both belts is shown in Figure 28. Slide the right axle left fully before tightening the set collar (E, Figure 27). 7. Check the traction drive tension and auger drive tension. Follow the procedures under AUGER/TRACTION DRIVE TENSION. 8. Make sure the auger stops when the auger drive lever is released. Make sure traction drive stops when the traction drive lever is released. If not, check the drive tension. If a problem exists, see your dealer. A B C E A B D Figure 27.
