Critical Wear Areas - Stanley Saber Series Safety, Operation & Maintenance Manual

BUCKET LINKAGE SHEARS
Check the gap at different points to make sure it is
between 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 all of the lower blade bolts. Refer to the Blade
Bolt Torque Chart on page 5-9 for the correct torque
values.

CRITICAL WEAR AREAS

Close attention must be paid to the "crosshatch"
hardsurfacing of the BLS. Inspect this area daily.
When the crosshatch is worn down almost to the
base metal surface, clean the surface by wire brush-
ing, preheat to 400°, and apply new underlayment
beads to the pattern using E-7018 welding rod or
E-70 series wire. After the pattern has been estab-
lished with underlayment beads, apply hardsurface
to the pattern. It is recommended that only one
pass (bead) of the hardsurfacing be applied. After
welding, wrap the upper in a heat blanket and allow
to cool slowly. Apply hardsurfacing on top of each of
the underlayment beads. DO NOT apply hardsur-
face DIRECTLY TO THE PARENT MATERIAL.
If, as a result of production considerations, the
crosshatch pattern has been worn down into the
base metal of the shear upper jaw, the Saber Tip can
be used as a guide for build up to proper profi le prior
to applying new hardsurfacing.
If the edge of the Saber Tip has been worn, it will
be necessary to remove the tip, rotate the new
front edge, and bolt into place. The surface of the
upper shear face should be built up (using E-7018
welding rod or E-70 series wire following pre-heat
procedures) to conform in profi le to the new Saber
Tip edge. Depending upon the model, this surface
should be fl ush with the Saber Tip edge, to 1/16"
above the edge.
Once the surface has been built up and ground to
profi le, the crosshatch hardsurface pattern can be
applied. Use 1-½" spacing in the hardsurface pattern,
as shown in fi gure 5-16.

CROSSHATCH
AREA
NOTICE
The area shown in fi gure 5-16 must be inspected
daily, and maintained whenever the crosshatch pat-
tern is almost worn down to the base metal surface.
If you have any questions, please call the Stanley
LaBounty Service Department at 218-834-6901. The
two areas in fi gure 5-16 labeled A and B are very
critical wear areas. When inspecting and maintaining
the shear, special attention must be given to these
areas.
