Boom
15. On the end of the boom pivot pin (10) closest to the
capscrew hole, mark the capscrew mounting hole
location. Coat the entire pin with anti-seize
compound.
16. Insert the pin (10) from the outside of the boom
assembly, making sure the marks (11) for the
capscrew mounting hole stay in line with the capscrew
mounting holes in the boom mounting hub. If necessary,
use a rawhide hammer to install the pivot pin.
17. Shim the boom as required using the shims (12),
saved, to maintain a .10" (2,5 mm) maximum gap
(13) between the boom mounting hub and the self-
aligning bearing (14) in the frame. If an additional
shim is required to maintain the maximum gap, the
extra shim MUST be inserted on the right side of the
boom.
Note: ALWAYS replace elastic locknuts with new elastic
locknuts to help ensure proper fastening.
18. After the pivot pin and shims are in place, use a
tapered punch to line up the capscrew hole in the pin
with the mounting holes in the hub. Insert the
capscrew (15), saved, through the hub and the pin.
Secure the capscrew in place with a new elastic
locknut (16). Tighten the elastic locknut securely.
19. Line up the rod end of one of the Lift/Lower
cylinders (17) with the self-aligning bearing on the
outer boom assembly.
20. Coat the entire Lift/Lower cylinder pivot pin (18) with
anti-seize compound. Insert the pin through the rod
end of the cylinder and the self-aligning bearing. If
necessary, use a rawhide hammer to install the pin.
Note: ALWAYS replace elastic locknuts with new elastic
locknuts to help ensure proper fastening.
21. Use a tapered punch to line up the capscrew
mounting hole in the pin with the mounting tabs on
the rod end of the cylinder. Secure the pin in place
with the capscrew (19), saved, and a new elastic
locknut (20). Tighten the elastic locknut securely.
22. Repeat Steps 19 thru 21 to assemble the Lift/Lower
cylinder to the other side of the outer boom.
