Step 4�
Remove the two (2) tensioning bolts to remove the pulley from the blow shaft. Use the
11 mm wrench to loosen the two bolts in front of the pulley tensioning bushing.
Step 5�
After both tensioning bolts are removed, thread
the same bolts in the adjacent holes using the
11 mm wrench. Threading the two bolts will
cause the pulley to separate from the tensioning
bushing.
Step 6�
When reinstalling the pulley on to the blower
shaft, ensure the engraved model number is fac-
ing away from the blower. Insert the pulley ten-
sioning bushing over the blower shaft and into
the pulley. Insert the tensioning bolts through the
two non-threaded holes on the tensioning bush-
ing to the threaded holes on the pulley.
Before securing the tensioning bushing, ensure
that the V groove in the pulley and the sheave
are inline. After the pulley location has been
adjusted, secure the pulley by tightening the
tensioning bolts using the 11 mm wrench.
