• Remove the belt cover (See Fig 26) • Engage the auger drive clutch lever, • Measure the distance between the belt guides and the belt (See Fig 28)° The distance should be 3/32" for each guide. • If adjustment is necessary, loosen the belt guide mounting bolts.

TO ADJUST THE FRICTION WHEEL if the snow thrower will not move forward, you need to check the track drive belt, the traction drive cable or the friction wheel it the friction wheel is damaged, it will need to be replaced_ See the To Replace Friction Wheel paragraph on page 21. If the friction wheel is not worn, check the adjustment, as foItows: • Disconnect the spark plug wire_ • Drain the gasoline from the_]as tank. • Stand snow thrower on the auger housing end. • Remove the bottom panel (See Fig, 29). o Position the shifter lever in first (1) gear. o Note the position of the friction wheel on the disc drive plate The right side of the friction wheel should be 3-3/8" fromthe left outer side of the discddve plate (See Fig. 30) If adjustment is necessary: • Loosen the jam nut "A" on the speed select rod Remove the ball joint from the shifter bracket Lengthen or shorten the rod by turning the adaptor to obtain the correct friction wheel position (See Fig. 31) • Reinstall the ball joint and tighten the jam nut. • Reinstall the bottom panel FRICTION WHEEL DRIVE PLATE 3-3/8 INCH FIG. 30 SPEEDSELECTROD -JAM NUT IFTER BRACKET ADAPTOR, BALL t FIG. 29 FIG. 31 2O SERVICE AN ADJUST E TS TO REPLACE FRICTION WHEEL If the snowthrower will not move forward, and the friction wheel is worn or damaged, you need to replace it, as follows: e Drain the gasoline from the fuel tank by rthe fuel lineoDrain the fuel and reinstall the emoving fuel line,. e Disconnect the spark plug wire, ® Stand the snow thrower end (See Fig., 32)., up on the auger housing e Remove the bottom panel (See Fig. 29). e Disconnect the right side track connecting rod,, ® Rotate the right side track until it is parallground (See Fig 33),, el to the • Remove the three (3) fasteners securing thwheel to the hub (See Fig. 32). e friction i i illl CAUTION: DRAINGASOLINEOUTDOORS AWAY FROM FIRE OR FLAME. o Move the shifter lever into first (1) gear. • Loosen the four No_, 10 keps nuts securing the bearing plate (See Fig..33), Do not remove the nuts., NOTE: Reassembly will be easier if you place a piece of tape over each of the carriage bolt heads on the inside of the motor mount before you remove the nuts,_ e Move the speed select lever into sixth (6) gear., e Remove the four No,, 10 keps nuts_ ® Remove the bearing plate, ® Slide the hex shaft to the right until the friction wheel can be removed.

IMPORTANT: TO iNSURE SAFETY AND PERFORMANCE LEVELS, ONLY ORIGINAL EQUIPMENT SHEAR BOLTS SHOULD BE USED.. WHEN REPLACING SHEAR BOLTS, BE SU RE TO REPLACE SHEAR BOLT SPACERS. To replace a broken shear bolt, proceed as follows: • Move the throttle to STOP and turn off all controls.. • Disconnect the spark plug wire. Be sure alt moving parts have stopped. • Lubricate the auger shaft zerk fitting (see the Maintenance section, pages !5-16). o Align the hole in the auger with the hole in the auger shafL Install the new shear bolt and shear bolt spacer provided. • Reconnect the spark plug wire. TO ADJUST TRACK Ifthe snowthrower does not moveforward evenly and the track slips slightly, you need to check the track, as follows: • Measure the distance between the top of the side plate and the inside of the track.. The distance should not be more than two (2) inches.. If the distance is greater, you need to adjust the track, as follows: o Loosen the bolts (A) (See Fig.,35) on both sides of the track assembly o Turn the cam washers equally on both sides° O Adjust the track to reduce slack, so that the distance between the top of the side plate and the inside of the track is not greater than two (2) inches. Be sure the cam washers are adjusted evenly or the track will be twisted (See Fig. 36). If the track becomes twisted, readjust the cam washers to the correct adjustmenL FIG. 34 DISTANCE SHOULDNOT BE TRACK GREATER THAN 2INCHES (A) CAM WASHER FIG. 35 ..............................._0UT OF AD...
