SHEAR MOUNTING FOR
SKIDSTEER MOUNTS
The shear is equipped with a mounting plate that will
mount to the loader in the same way as the origi-
nal equipment. See Figure 3-1. Refer to the loader
manual for specific mounting instructions.
SHEAR MOUNTING FOR
STICK (OR BOOM) MOUNTS
1.
Locate level, firm ground, such as a concrete floor,
for installation. Place the shear on the ground with
the mounting bracket facing the excavator (figure
3-2). It may be necessary to block up the rear end of
the shear to allow the stick or boom tip to be aligned
with the mounting bracket. For second member, or
boom mounts, it may be necessary to place the
shear on the ground upside down with the mounting
bracket facing away from the cab (Figure 3-3).
2.
Remove the bucket or other attachment following
the manufacturer’s recommended procedure. For
second member, or boom mounts, the stick will also
need to be removed before installing the shear.
3.
Take care to plug the hydraulic hoses when dis-
connected to prevent contamination from entering
the hydraulic system.
4.
Walk the excavator into position, lining the stick
into the stick pivot of the attachment (Figure 3-4).
5. Pin the excavator’s stick and attachment stick
pivot together.
6.
Use the bucket cylinder, if necessary, to align
the excavator bucket linkage with the linkage con-
nection of the shear bracket. Pin this connection
together.
7.
Double-check all pins, collars, and related fasten-
ers to ensure they are properly installed and tight-
ened.
8.
See the electrical and hydraulic installation in this
section, pages 3-4, and 3-5.
