• 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.

• Raise the snow thrower to this 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 fiat idler
pulley to the outside of the belt. See figure 18.
• Use the R.H. tension adjusting chain to pull the fiat
idler pulley in against the auger belt. Pull the chain
out as far as the inside hairpin clip will allow and
then fasten the chain in place using the 1/8' hairpin
clip which was removed earlier. See figure 18.
• Use the L.H. tension adjusting chain to pull the flat
idler pulley in against the drive belt. Pull the chain
out as far as the inside hairpin clip will allow and
then fasten the chain in place using the 1/8 mhairpin
clip which was removed earlier. See figure 18.
IMPORTANT: The inside hairpin clips are factory
assembled to the fourth link of the L.H. chain and
the seventh link of the R.H. (;hain. (Links are
counted from the end of the Chain which attaches
to the spring.) If the clips are accidentally removed,
they must be reassembled to the original link in
order to set the correct belt tension.
