SECTION 9: SERVICE ADJUSTMENTS

Pulley Alignment

Improper pulley alignment sharply reduces the
effectiveness of power transmission and belt life
expectancy.
To align the pulleys:
1. Unplug the shaper!
2.
Remove the motor cover from the side of the
shaper cabinet.
3. Check the alignment with a straightedge. If
the pulleys are in alignment, the straightedge
should touch two sides of each pulley evenly.
See Figure 52.

Disconnect power from
the machine when per-
forming any service
adjustments. Failure to
do this may result in seri-
ous personal injury.
4.
If pulleys are parallel with each other, but
not in line, remove the belt from the spindle
assembly and slide the spindle cartridge
assembly either up or down.
5. Inspect for tilt on the motor pulley. If the pul-
ley is tilted, loosen the four bolts holding the
motor onto the motor plate. Wiggle the motor
into position. Do not loosen the bolts that hold
the motor onto the split housing; this plate is
pre-set with blocks that hold it in position and
it cannot be adjusted. The side cover can be
removed from the shaper to improve access
to the motor.
6.
Inspect your results. If satisfactory, tighten
all fasteners. Remember to tighten the bolt in
the split housing that holds the spindle car-
tridge in position. DO NOT over-tighten. Cast
iron threads are more easily stripped than
steel.
7. You can also align the motor pulley by raising
or lowering it along the motor shaft. Loosen
the two setscrews and tap into desired posi-
tion with a dead blow hammer.
