Belt Installation, Adjustment And Replacement - Sears C 151 61822 4 Owner's Manual

BELT INSTALLATION,
AND REPLACEMENT:
WARNING
The belt tension arm is spring loaded & needs to be
held firmly while displacing to prevent injury
IMPORTANT:
When aligning or replacing the
snowblower pulley (item 4), You must clean the parts
and apply some "Loctite" 2760 on the key of the
pulley and the set screws of the bearing and pulley.
Tighten firmly.
SNOWBLOWER BELT:
a) Lower the snowblower to the ground.
b) Remove the belt guard.
c) Remove tension on the belt by lowering the
tension arm (item 1)
d) Loosen the knob (item 2) on the bracket that holds
the bearing (item 3).
e) Install the belt as shown.
f)) Adjust the bracket by pushing on the bearing (item
3) to apply a slight pressure on the back of the belt
(just enough to hold the belt in place). It is normal
that the bearing is off centre (towards the vehicle)
on the pulley. Just make sure that it does not
come into contact with the wall of the pulley.
g) Tighten firmly with the knob.
h) Apply tension on the belt by pulling up the tension
arm (item 1). To obtain the proper tension, the
distance between the coils of the spring (item 6)
should be .25'' (1/4'') approx.
If not, remove the bolt, sleeve and the spring from
the original hole and reinstall them in the second
hole (item 5). This will apply more tension on the
belt helping to prevent it from slipping in the
pulleys.
i) Engage the snowblower for a few seconds under
supervision. Stop the engine. Inspect the belt to
make sure it does not interfere with any parts; that
it is well inserted in the pulleys and that it has not
flipped on it's side while still on the pulleys. The V
of the belt must be in the V of the pulleys. The
back of the belt must rest on the flat pulleys (D)
as shown.
j) Reinstall the belt guard.
k) Use genuine belts only, they are specifically
fabricated for this application.
NOTE: There must be a good tension on the belt at
all times. If spring is damaged or stretched, you must
it.
