The V-belts and their respective pulleys have been
professionally aligned at the factory. If there is a requirement
to remove/replace or adjust the pulleys, perform the
following steps.
1. Select the proper-sized pulley both in outside diameter
and arbor size. Use approved parts to ensure the
component compatibility.
2. A change in pulley diameters may require specifically
sized V-Belts. Contact Multiquip Parts Department to
ensure V-Belt compatibility.
3. Remove the V-Belts from around the pulleys, following
steps in the V-Belt Replacement and Tension
Adjustment section.
4. Remove the set screws that secure the pulleys to the
respective shafts (PTO shaft) for engine pulley or the
(blade shaft) for the blade shaft pulley.
5. Remove the pulley by sliding it off the shaft.
6. Reorient the new pulley on the shaft, and ensure
precise pulley alignment by utilizing an accurate
straight edge (see Figure 55 and Figure 56).
