Boom
5. Install the top, bottom and side wear pads to the rear
of the third boom section. If the machine is equipped
with Auxiliary hydraulics, the top left wear pad is
already installed.
6. Lay the two extend chains (11) on the top of the third
boom section with the threaded clevis ends toward
the rear of the boom. Coat the threads on each
clevis with multi-purpose grease and insert the
clevis’ through the holes in the anchor plate. Install a
washer and locknut onto each clevis. Tighten the
locknut enough so the threads are even with the top
of the locknut.
7. At the rear of the third boom section, place the male
ends of the hydraulic hoses in the third boom section
to prevent damage while installing the third boom
section into the second boom section.
8. Grease the sections of the boom in areas where the
wear pads will slide.
9. Using a suitable sling, carefully slide the third boom
section into the second boom section. Leave enough
room at the front of the boom to install the remaining
wear pads.
10. Install the top and side wear pads to the inside of the
second boom section.
11. Pull the male ends of the hydraulic hoses out the
rear of the third boom section. Stretch the hoses out
straight behind the machine.
12. Assemble the hoses to the hose reel (12) at the rear
of the boom.
Note: Keep the hoses in the same order as they come
from the hose clamps. DO NOT allow the hoses to cross.
13. Tie the strings (positioned inside the first boom
section) to the male end of the hydraulic hoses
coming off the bottom of the hose reel assembly.
14. Working from the front of the boom, pull each hose
through the boom assembly through the opening at
the bottom of the first boom section.
15. Remove the strings from the hoses.
16. At the front of the first boom section, assemble the
hose assemblies and tube assemblies to the
mounting plate (13).
Note: Where the hose assemblies come out of the outer
boom, lubricate the radius in the first boom section with
soap and water to allow proper tensioning of hoses.
17. Place the retract chain up around the retract chain
sheave on the right side of the boom. Stretch the
chain forward and place the clevis between the two
anchor plates. Align the hole in the clevis with the
second hole from the rear of the anchor plates.
