MSD SABER SERIES SHEARS
Keep hands away from moving shear. Be sure the shear will not move while checking the blade gaps
or severe injury could result.

CUTTING BLADE SHIMMING
After blade rotation, use the following instructions to shim to the proper blade gap. Shimming is necessary
if the gap exceeds 0.030” (0.75 mm). For most shearing applications, this gap should be maintained at 0.010
to 0.020" (0.25 to 0.50 mm),
but see the table below for the specifi c gap for your shear.
The gap may be
shimmed down to 0.005” (0.13 mm) if jamming becomes a problem, especially when processing thin mate-
rials. Shim only the lower blades.
1.
To check for blade gap, close the shear until the secondary blades in the upper and lower shear begin to
bypass (see
Figure 5-18
). Start with the thickest shims and check to see how many shims can be slipped
between the blades and record this amount. Another method is to use a feeler gauge to check the blade gap
and record it.
2.
The whole shim set adds up to 0.125” (3.2 mm). If all shims can be slipped between the blades it will
be necessary to replace the blades. Do not shim the lower blades out more than 0.125" (3.2 mm). This may
cause structural damage to the shear.
3.
Close the shear further until the primary blades begin to bypass (see
Figure 5-19
). Again, check to see
how many shims can be slipped between the blades (or use the feeler gauge). Record this gap also. If the
blades have been rotated properly at the correct intervals, the blade gap should be even over the entire span
of the blades. If the gap is not even, contact your Stanley LaBounty dealer.
4.
Once the blade gap is checked and recorded, open the shear. Shim the lower blades by using the same
amount of shims that you were able to slip between the blades earlier.
5.
To install the shims, loosen the lower blade bolts and move the blades out slightly. Slide the shims be-
tween the lower blades and the existing adjustment plate. Tighten the blade bolts until snug.
6.
Cycle the shear slowly to the full-closed position. Check the gap at different points to make sure it is be-
tween 0.010" and 0.020" (0.25 and 0.50 mm). If it is too tight, you may need to remove a shim.
7.
When the gap is correct, apply the correct torque to the blade bolts. Refer to the Dry Bolt Torque Charts in
this section for the proper torque value.
