Gauge Blocks; V-Belt Service - Grizzly G0450 Instruction Manual

Gauge Blocks

Tools Needed:
6' Long 2x4 ........................................................ 1
Miter Saw (or Circular Saw) .............................. 1
Jointer ................................................................ 1
Table Saw ......................................................... 1
The gauge blocks described here will be required
to complete most of the service procedures in this
section. After you have made them, they can be
conveniently stored inside of the sander cabinet
for future use.
To make the gauge blocks:
1. Edge joint the concave edge of the 2x4 flat
on a jointer, as shown in Figure 27.
Figure 27. Edge jointing on a jointer.
2.
Place the jointed edge of the 2x4 against the
table saw fence and rip cut just enough off
the opposite side to square up the two edges
of the 2x4, as shown in Figure 28.

3. Cut the 2x4 into two even pieces to make two
36" long wood gauge blocks.
Note: The Steps 1 & 2 can be skipped, but
having these wood gauge blocks at an even
height is critical to the accuracy of your over-
all adjustments.

V-Belt Service

Tools Needed:
Hex Wrench 5mm .............................................. 1
Wrench 19mm ................................................... 2
Straightedge (at least 24") ................................. 1
Ruler .................................................................. 1
Tension
New V-belts often stretch and loosen up during
the first 16 hours of use. After this period, they
should be inspected and re-tensioned if neces-
sary.
Proper tension is important for optimum power
transmission. However, too much tension may
cause premature bearing failure.
The correct V-belt tension is achieved when the
V-belts can be deflected
the middle with moderate pressure. See Figure
29 for an example of how to perform a V-belt
deflection test with a straightedge and ruler.

straightedge and a ruler.
