    • Wrap a piece of tape around the upper half of the tensioner bolt to mark the location of the second nut.

    • Use a 9/16 inch wrench to loosen the nut on the lower half of the tensioner bolt until the motor can slide forward as much as possible.

    • During reassembly, reference the tape to position the outer nut into the same location as before to ensure proper belt tension.

    • Use a universal puller to remove the pulley from the cutter wheel shaft:

    • Attach the universal puller to the pulley using the three bolts provided on the pulley.

    • Use a wrench to torque down the center screw to slowly loosen the pulley.

    • This may take a lot of force.

    • If the pulley seems to be stuck after significant pressure is applied with the universal puller, use a blowtorch to apply heat where the pulley contacts the shaft.
