Disassembly (Fig. 32)
IMPORTANT: Make sure to remove and neutralize
chemicals from spray components before disas-
sembly. Wear protective clothing, chemical resist-
ant gloves and eye protection during repair.
1. Park machine on a level surface, lower spray booms,
stop engine, engage parking brake and remove key
from the ignition switch.
2. Loosen hose clamp and remove supply hose from
tee fitting (item 6) on spray boom.
3. Support spray boom to prevent it from falling.
4. Loosen two (2) cap screws (item 9) and lock nuts
(item 8) to allow breakaway springs (item 19) to fully ex-
tend.
5. Complete disassembly boom hinge as required us-
ing Figure 32 as a guide. If pivot bracket (item 11) is to
be removed from machine, disconnect boom lift cylinder
(not shown) from pivot bracket (see Boom Lift Cylinder
Removal in the Service and Repairs section of Chapter
4 -- Hydraulic System).
6. Clean all removed components. If pivot bracket was
removed, inspect bushings and pivot pin for damage or
wear. Replace bushings and/or pivot pin if required.
Assembly (Fig. 32)
1. If pivot bracket (item 11) was removed from machine,
lightly lubricate bushings (item 12) with motor oil before
assembly. Connect boom lift cylinder (not shown) to piv-
ot bracket (see Boom Lift Cylinder Installation in the Ser-
vice and Repairs section of Chapter 4 -- Hydraulic
System).
2. Make sure that hinges (item 1) are securely fastened
to pivot bracket (item 11) and boom (item 5). The boom
hinge uses four (4) backing plates between the boom
and flange nuts.
3. Position boom hinge to pivot bracket hinge. Make
sure that rubber boots (item 2) are placed at hinge junc-
tions and that rib on boots is toward the top of the boom
(Fig. 33).

tween the face of the spring retainer and the hinge cast-
ing (Fig. 34).
