Spotter. (Refer to Figure K-38.)
The spotter is normally disassembled to replace components or to inspect and remove the short wear
pads, long wear pads, and spotter hydraulic cylinder.
Disassembly.
a.
If necessary, remove the spotter slide from the end of the spotter inner box (1,
Figure K-38) and set aside.
b.
Tag and disconnect the hydraulic extension hose (2) from the fitting on the hydraulic
manifold at the rear of the spotter outer box (3).
c.
Tag and disconnect the hydraulic retraction hose (4) from the fitting on the hydraulic
manifold at the rear of the spotter outer box (3).
d.
Remove the cotter pin (5) securing the cylinder clevis pin (6) in the heel of the spotter
outer box (3).
e.
Remove the cylinder clevis pin (6), lower clevis pin spacer (7), and upper clevis pin
spacer (8).
f.
Push the spotter inner box (1) and spotter hydraulic cylinder (9), as an assembly, from
the front and slide it until the rear of the spotter inner box (1) extends out the rear of the
spotter outer box (3) exposing the rear of the hydraulic cylinder (9).
g.
Pull the spotter inner box (1) and spotter hydraulic cylinder (9), as an assembly, out from
the heel end of the spotter outer box (3). Support the spotter inner box (1) with a sling
as it is pulled out of the spotter outer box (3).
NOTE
The wear pads (10 and 11) on the spotter inner box (1) prevent it from
being removing by sliding out from the front of the spotter outer box (3).
Inspection.
a.
Inspect the two short wears pads (10, Figure K-38) and two long wear pads (11) on the
spotter inner box (1) for wear. Replace if worn.
b.
Inspect the two short wears pads (12) and two long wear pads (13) on the spotter outer
box (3) for wear. Replace if worn.
Reassembly.
a.
Support the spotter inner box (1, Figure K-38) and spotter hydraulic cylinder (9), as an
assembly, with a sling. Slide the front of the spotter inner box (1) into the heel end of the
spotter outer box (3). Push forward until the clevis on the cylinder end of the spotter hydraulic
cylinder (9) is aligned with the mounting location in the heel of the spotter outer box (3).
b.
Secure the cylinder end of the spotter hydraulic cylinder (9) in the heel of the spotter
outer box (3) by installing the upper clevis pin spacer (8), lower clevis pin spacer (7), and
inserting the cylinder clevis pin (6).
c.
Secure the cylinder clevis pin (6) in the heel of the spotter outer box (3) by installing the
cotter pin (5).
