10. Label and remove the auxiliary hoses (16 and 17)
from the tube assemblies (15) at the mounting plate.
Cap the hose ends. Tie a string to each of the hoses
to aid in the installation of the new hoses.
11. Label and remove the four hoses from the hose reel.
The center bolt (18) can remain in place to hold the
hose reel and side plates together.
12. Remove the elastic locknut (19) and flat washer (20)
from the lower retaining shoulder bolt (21). While
pulling the shoulder bolt out, catch the spacers (22)
from between the plates as the bolt is removed. Pull
the bolt out far enough to remove the hoses from the
hose reel.
13. Pull the four hoses from the lower part of the hose
reel out from between the outer boom and the
primary intermediate boom sections. Remove the
strings from the hoses, but leave the strings inside
the boom. Carefully lay the hoses out behind the
back of the boom.
After the hoses are removed from between the outer
and primary intermediate boom sections, insert the
shoulder bolt (21) through the plates, inserting the
spacers (22) between the plates as the bolt is
inserted. Reassemble the flat washer (20) and
elastic locknut (19) to hold the shoulder bolt in place;
DO NOT fully tighten at this time.
14. Remove the elastic locknut (23) from the upper
retaining capscrew (24). While pulling the capscrew
out, catch the spacers (25) from between the plates
as the capscrew is removed. Pull the capscrew out
far enough in order to remove the hoses from the
hose reel.
After the hoses are removed, insert the
capscrew (24) through the plates, inserting the
spacers (25) between the plates as the capscrew is
inserted. Reassemble the elastic locknut (23) to hold
the capscrew in place; DO NOT fully tighten.
15. At the rear of the boom, locate the inner boom
extend chain locknut (26). Measure the amount of
threads protruding beyond the elastic locknut and
record that measurement for reassembly.
16. Using a 1-7/16" socket and a 12" extension, loosen
the elastic locknut (26) until the nut is held on by a
couple of threads. DO NOT remove the elastic
locknut at this time.
17. Return to the operator’s cab, start the engine and
extend the boom approximately 2" (51 mm). Retract
the boom slightly until there is slack in the inner
boom extend chain. Shut the engine OFF.
