Pulley Alignment - Grizzly G1026 Owner's Manual

Pulley Alignment

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 the alignment of the pulleys:
1.
DISCONNECT MACHINE FROM POWER!
2.
Remove the rear cover.
3.
Hold the straightedge up to the pulleys to
determine if they are both aligned and paral-
lel, as shown in Figure 72.
