SERVICE AND ADJUSTMENTS
FIGURE 27
REPLACING AUGER BELT
• Raise the snow thrower to the transport position.
• Release the spring tension on the drive belt idler.
• Release the spring tension on the auger belt idler.
• Remove the belt cover and loosen the belt keeper
bracket (items 18 and 19 on page 20).
• Remove the auger belt from the clutch/idler as sem bly
and from the spiral auger hous ing.
• Install new belt around top of auger drive pulley and
underneath the two side idler pulleys. Twist the belt
1/4 turn to seat it in each idler pulley.
• Reinstall the belt cover and tighten the belt keeper
brack et (items 18 and 19 on page 20).
• Assemble the belt onto the clutch/idler assembly as
instructed for fi gure 23 on page 13.
LIFT RELEASE CABLE ADJUSTMENT
• If the lift rod does not lock the snow thrower
se cure ly in the transport position, loosen the upper
hex nut on the lift bracket a few turns and tighten the
lower hex nut. See fi gure 17 on page 10.
• If the lift rod fails to unlock completely to lower the
snow thrower to the ground, loosen the lower hex nut
on the lift bracket a few turns and tighten the upper
hex nut. Refer to fi gure 17 on page 10.
SPIRAL AUGERS
• The spiral augers are secured to the auger shaft with
two shear bolts and hex lock nuts. If you hit a foreign
object or if ice jams the augers, the snow thrower is
designed so that the bolts will shear.
• If the augers will not turn, check to see if the shear
bolts have sheared. See fi gure 27. Two re place ment
shear bolts and hex lock nuts have been provided with
the snow thrower. For future use order part number
710-0891 shear bolt and number 43064 hex lock nut.
CAUTION:
Before servicing or adjusting
the snow thrower, shut off the engine,
remove the spark plug wire(s), set the
parking brake and remove the key from the
tractor ignition.
SKID SHOE, LEVELING SHOE ADJUSTMENT
(The snow thrower must be attached to the tractor for
correct adjustment of the shoes.)
• The skid shoes regulate the distance the scraper
plate is raised above the plowing surface. They are
mounted on each side of the spiral auger housing.
The leveling shoes help maintain the snow thrower
in a level position. They are mounted just behind the
auger housing.
• When re mov ing snow from a gravel drive way or an
uneven surface, it is ad vis able to keep the scraper
plate as high above the surface as possible to prevent
possible damage to the spiral auger. On a smooth
blacktop or concrete sur face, keep the scraper plate
as close to the surface as pos si ble.
• To adjust the skid shoes, raise the snow thrower off
the ground and place a wood block under each end
of the scraper plate. Loosen the six hex nuts securing
the skid shoes to the housing. Adjust the skid shoes
up or down to the desired position and tighten the
nuts securely. Both skid shoes should be the same
height to keep the hous ing and the scraper plate level.
See fi gure 28.
• The skid shoes may be turned to face either in or
out. In order to obtain the lowest setting, where the
scraper blade fully contacts the ground, the skid
shoes must be facing out as shown in fi gure 28.
• Before adjusting the leveling shoes, make sure the
skid shoes are properly adjusted. With the snow
thrower in the lowered position, loosen the bolts which
fasten the lev el ing shoes to the thrower and adjust the
lev el ing shoes to solidly contact the ground. Re tight en
the bolts. See fi gure 28.
