PULLEY ALIGNMENT AND REMOVAL
Pulleys will remain aligned during belt tension if
inside pivot mount bolts (item 3) have not been
loosened. Check alignment of pulleys by placing a
straight edge along flat face of both pulleys. Check
alignment at lower and upper end of pulley face
when belt is tensioned.
If pulleys are not correctly aligned check tightness
of pivot bolts (3). Drive tube inner mount (4) is
slotted and may be moved toward front, rear or
shimmed for height adjustment to correct pulley
alignment. Mnt-FL-0039.
To relocate pulleys on drive and cuttershaft, first
loosen belt tension and check for shaft movement
to ensure they are not loose or have moved. Mark
present location of bushing on shaft for future
reference. Pulleys are locked to shaft by a tapered
hub bushing. Loosen socket head set screw located
above key. Loosen and remove all mounting cap
screws in bushing. Insert cap screws in all threaded
jack screw holes on bushing. Start with the screw
furthest from the bushing slot and tighten all screws
alternately and progressively. Keep turning the
screws in small equal amounts until the bushing
and pulley start disengaging. Mnt-FL-0040.
Uneven pressure on the jack screws may break the bushing flange.
