REPLACING THE DRIVE BELT
Service & Maintenance
1. Remove the belt guard, following Fig. #15.
2. Remove the chipper blade access cover.
3. Remove chipper blades from the rotor.
4. Loosen the belt guide surrounding the rear of the trans-
mission belt.
5. Remove the old belt. The easiest way is to cut the belt
and slide it out.
6. Insert the new belt into the rotor housing and hook into
one of the chipper slots in the rotor. Rotate the rotor to
move the belt above the fan. Be sure the belt goes under
the fan blades and on top of the fan.
7. Pull the excess new belt to the rear of the machine and
slide it onto the top pulley of the engine. If the beaterbar
belt is attached the new transmission belt will have to be
threaded through the beater bar belt.
8. Position the belt onto the transmission pulley, sliding it
between the belt guide.
9. Engage the bail and set the position of the transmission
belt guide. There should be 1/8” of clearance between
the belt guide and the top of the belt.
10. To set the proper tension of the belt, set the idler arm so
there is approximately 1/8” to 1/4” of deflection on the
belt.
10. Reattach the belt covers and operate the unit as in-
structed.
