BELT REPLACEMENT
DRIVE MECHANISM BELT
a) Remove the snowblower’s belt guard and release
the tension on the belt. Remove the belt from the
snowblower and the drive mechanism pulleys.
b) Remove the drive mechanism, be careful not to
drop.
c)
NOTE:
Before proceeding with this step, notice
carefully how the belt guide is installed to avoid
damage to the belt when re-installing. Remove
the bolt which retains the tension pulley and the
belt guide. Replace the belt and re-install the
tension pulley and belt guide. Before tightening
make sure the belt guide does not touch the belt
at any time.
d) Re-install the drive mechanism.
MANUAL P.T.O. CLUTCH:
With the engine turned off
, engage and disengage
the P.T.O. clutch and verify to make sure the belt
does not come in contact with the belt guide or any
other part.
ELECTRIC P.T.O. CLUTCH:
Make sure the belt does not come in contact with the
belt guide or any other part.
SNOWBLOWER BELT
IMPORTANT:
This verification MUST be done before installing a
new belt.
a) Make sure the pulleys are well installed and not
damaged or rusted. If rusted, properly clean the
inside of the pulley with sandpaper or replace
completely.
b) Make sure the flat pulley is installed in the correct
hole as specified below:
1/2"
wide
belt
Fasten the pulley in the hole closest to the front.
5/8"
wide
belt
Fasten the pulley in the hole closest to the rear.
NOTE: See subframe manual for V-belt part
number.
NOTE: These belts have a similar life span,
however, the 1/2" belt must not be used on
tractors of more than 20 HP.
BELT REPLACEMENT
a) Lower the snowblower to the ground.
b) Install the V-belt as illustrated below.
c) Put tension on the belt by pulling up the tension
arm.
d) Let the snowblower run for a few seconds under
supervision. Disengage snowblower, turn off
engine, re-verify routing of belt by making sure it
does not touch any part at any time and that it
has not flipped on its side while still on the
pulleys.
e) If in the future, for any reason, the belt flips on its
side, follow this step to prevent it from repeating.
Remove the belt & turn it 180° (left strand of belt
on right side and vice versa). If this is not done,
the belt will continue to flip and will break the
inner cords of the belt at every 3 to 4 inches.
f) If after a certain time, the belt stretches and the
left flat pulley (item 3) becomes closer to the
ground, you must compensate by raising the right
side flat pulley (item 4) into the upper hole.
g) Use genuine belts only, they are specifically
fabricated for this application.
h) Reinstall the belt guard.
NOTE
: Belts must be under high tension at all times.
If spring is damaged or stretched, you must replace
it.
