Aligning Pulleys
Pulley alignment is important to the performance
of your shaper. If the pulleys are just slightly out of
alignment, the shaper may suffer from power loss
and decreased V-belt life. When the pulleys are
parallel and aligned with each other, they are said
to be coplanar—in the same plane.
Checking Pulley Coplanarity
Tools Needed
Precision Straightedge ...................................... 1
To check alignment of pulleys:
1.
DISCONNECT MACHINE FROM POWER!
2.
Open cabinet access door.
3.
Hold straightedge up to pulleys to determine
if they are both aligned and parallel, as
shown in Figure 74.
— If pulleys are not parallel or aligned with
each other, perform appropriate steps in
following procedures.

check pulley alignment.

2.
Remove motor access panel, then loosen the
four motor mounting hex bolts, as shown in
Figure 75. It may be easier to access back
bolts from cabinet access door.

3.
Using straightedge as a guide, adjust height
of motor until pulleys are aligned, then re-
tighten hex bolts.
Note: When adjusting spindle alignment,
take not only spindle height into account, but
also consider motor and motor pulley angle in
relation to spindle (see Figure 76).

4.
Use level to check pulley angles, and adjust
hex bolts until parallel.
5.
Replace motor access panel and ensure
V-belt is properly seated for desired speed
(see Speed Changes on Page 25) before
reconnecting machine to power.
