-18- G8621 Heavy-Duty Sliding Table Shaper
Pulleys & V-Belt
SECTION 5: ADJUSTMENTS
Improper pulley alignment sharply reduces the
effectiveness of power transmission and belt life
expectancy. To align the pulleys:
1. Remove the motor cover from the back of
the shaper cabinet to expose the motor and
pulleys.
2. Check the alignment with a straightedge. If
the pulleys are in alignment, the straightedge
should touch two sides of each pulley even-
ly as in Figure 25.
3. If the pulleys are parallel with each other, but
not in-line, the motor needs to be adjusted.
4. This process is easiest with the help of
another person. Loosen the four bolts that
attach the motor to the motor base. One per-
son should slide the motor either up or down
while the other person measures the align-
ment of the motor pulley and the spindle pul-
ley with a straightedge.
5. When the motor pulley and the spindle pulley
alignment are correct, tighten the motor to
the motor base.
6. Inspect your results. If satisfactory, double-
check that the mounting bolts are tight.
7. You can also make small adjustments in the
motor pulley alignment by raising or lowering
it along the motor shaft. To do this, loosen
the two setscrews (one is shown in Figure
25) which are in the lowest groove of the
motor pulley and move the pulley into posi-
tion. Tighten the setscrews when the align-
ment is satisfactory.
