LOWER WEAR PLATE
REPLACEMENT
The lower wear plates protect the lower cross plate
from excessive wear. Inspect these plates every 80
hours and replace them before the cross plate is in
danger of being exposed to wear. Use the following
instructions to replace the lower wear plates.
1. Preheat the surrounding area to about 200°F
(100°C) to remove moisture. Preheat the area within
six inches (150 mm) of the lower wear plates to a
minimum of 400°F (200°C) and a maximum of 450°
(230°C). Maintain this temperature range throughout
the process. Temperature/melt sticks are available
from Stanley LaBounty.
2. Air-arc the old wear plates to remove them com-
pletely from the nose plate.
3. Use a grinder to make sure the surfaces are fl at
and smooth with all weld and carbon residue re-
moved. If necessary, build up the edges of the cross
plate before installing the new wear plates. See the
lower shear build-up instructions in this chapter.
4. Position the new front wear plate so it is centered
across the width of the cross plate. The holes in the
wear plate should be aligned with the holes in the
nose plate. This should leave a gap between the
top of the wear plate and the top of the nose plate
that will be fi lled with weld later (see Figure 5-35).
Clamp the wear plate into position, bring the pre-
heat back up to 400°F (200°C). Tack weld in place.
Check temperature regularly during this procedure.
Maintain 400-450°F (200-230°C). Do not exceed
450°F (230°C).
The lower shear must be grounded when weld-
ing on the lower shear to prevent the possibility
of electric shock.
