MSD SABER SERIES SHEARS
CRITICAL WEAR AREAS
continued
CROSSHATCH HARDSURFACING
See Figure 5-21.
A. In some applications, this area can be built up
for added wear resistance. Taper and blend the top
edge of the weld procedure.
B. Maintain build-up in this critical area. Area to be
built up fl ush with the top edge of the blade. Use
E-7018 or E-70 series wire.
C. Maintain profi le and build-up in this area. Blend
the bottom edge. This area must be maintained to
prevent wear into the Saber Tip reverse edge, which
rests just behind it.
D. Use E-7018 or E-70 series wire. Apply hardsur-
face allowing 1/16" space in from the edge both
sides. Do not apply hardsurface directly on an edge.
E. Apply the crosshatch pattern using 1.50" spacing.
F. Build up this area so that the bottom edge pro-
trudes 1/16" beyond the end of the blade. Taper and
blend the top edge; use E-7018 or E-70 series wire.
NOTICE
Apply hardsurfacing on top of the underlayment
beads DO NOT APPLY HARD SURFACE DIRECTLY
.
TO THE PARENT MATERIAL. It is important to use
an air operated slag peener on each pass of weld to
relieve stress.
NOTICE
• Figure 5-22 is not to scale; it has been enlarged for the purpose of illustration.
• Apply hardsurfacing on top of the underlayment beads. DO NOT APPLY for all build-up and welding
procedures; use E-7018 welding rod, or E-70 series wire, following the welding procedures outlined on pages
5-19 through 5-20 of this manual.
• Use build-up template provided in the maintenance kit, to profi le upper.
• If restoring the profi le of the tip pocket is unattainable through welding and grinding, please contact
LaBounty Service Department: (800) 522-5059. There is a tip grinding tool that follows a template that will
restore the seat to factory specifi cations.
