AUGER BELT
Make sure the auger belt is correctly assembled
to
the snow thrower. The belt must pass over the top
of the auger pulley and then twist 1/4 turn to pass
underneath
the two side idler pulleys on the snow
thrower. The "V" side of the belt must seat in the
grooves of all three pulleys. See figure 17.

VIEWED FROM REAR
Raise the snow thrower to the transport
position.
Place the auger belt around the bottom rear pulley
on the clutch/idler
assembly and between the two
pulleys on the lower idler arm. Keep the flat idler
pulley to the outside of the belt. See figure 18.
Pull the flat idler pulley against the auger belt using
the R.H. tension adjusting chain. For correct belt
tension, pull the chain as far as the inside hairpin
clip will allow and then reinstall the outside 1/8"
hairpin clip into the chain. See figure 18.
IMPORTANT:
If the R.H. inside hairpin clip is re-
moved, reinstall it in link #2 (counted from the end
of the chain attached
to the spring).
Pull the upper flat idler pulley against the drive belt
using the L.H. tension adjusting chain. For correct
belt tension, pull the chain as far as the inside
hairpin clip will allow and then reinstall the outside
1/8" hairpin clip into the chain. See figure 18.
IMPORTANT:
If the L.H. inside hairpin clip is re-
moved, reinstall it in link #8 on tractors with 6"
diameter engine pulleys or in link #5 on tractors
with smaller engine pulleys. (Links are counted
from the end of the chain attached to the spring.)
