36. Assemble bottom wear pads on 2nd section pad plate,
raise the 3rd-4th-5th and cylinder assembly high enough
in the 2nd to allow pad plate with pads to slide between
the sections, place retract cables in the grooves in the
bottom pad plate, as the boom sections are slide
together, retract cables will pull thru these grooves, use
appropriate hardware and fasten the pad plate to the
bottom of the 2nd section.
37. Install a nut on the threaded ends of the 4/3/2 retract
cables, to keep the cable ends from pulling thru the
anchor as the sections are pushed together.
38. Push the 3rd-4th-5th and cylinder assembly inside the
2nd section, until it is within 36 in (90 cm) of full insertion.
39. Install side wear pads with appropriate shims on front
inside of the 2nd section, shim according to calibration
instructions, or as pads were originally removed and
tagged. Assemble 1/2/3 extend cable sheaves and pins
with the appropriate hardware to the 2nd section top
plate, assemble cable keeper/spacer bar plates to 2nd
section, install cable guide and wear pad to the top of the
2nd section.
40. Slide the 3rd-4th-5th and cylinder assembly into the 2nd
section until the extend cylinder collar bottoms out in its
anchor pocket in the rear of the 2nd section or the 3rd
section side plates bottom out on the doubler plates on
the rear of the 2nd section. Use caution as the 4/3/2
Retract cable threaded ends get close to the grooves in
the lower front pad plate, adjust as necessary to allow
proper placement
41. Cylinder length adjustment may be necessary to
properly position cylinder collar in the anchor pocket with
the 3rd section side plates bottoming out on the doublers
in the rear of the 2nd. A hydraulic power source may
have to be utilized to adjust the cylinder length. Install
appropriate hardware fastening the extend cylinder
collar to the cylinder mounting channels in the rear of the
2nd section boom. Ascribe mark on the 3rd section at full
retraction will aid in cable tensioning for proper boom
sequence later.
42. Assemble top rear wear pads with the cam plates to the
top of the 3rd section. See step #11 for pad installation
detail.
43. Assemble 3/2/1 Retract cable button ends into anchors
points in the rear of the 3rd section. Install keeper plates
and capscrews. Assemble with loctite 243.
44. Assemble 2nd section retract sheaves and pins into the
inside of the 2nd section using proper hardware and
Loctite 243, reeve 3/2/1 retract cables, anchored to 3rd,
over sheaves attached to 2nd section and install upper
keeper capscrew and lower rear pad, this pad serves as
a cable keeper, lower pad and side pad for the rear of the
section.
45. Pull threaded ends of 3/2/1 retract cables, now under the
2nd section, towards the front of the boom.
46. Suspend assembled boom sections, position of extend
cylinder butt plate is holding valve down, rotate rod
assembly to achieve proper orientation, place retract
cables to avoid damage, and slide assembled boom
sections into the 1st section approximately 36 in (90
cm). Keep boom assembly suspended to avoid damage
to the retract cable.
47. Assemble bottom wear pads on 2nd section pad plate,
raise the 2nd-3rd-4th-5th and cylinder assembly high
enough in 1st to allow plate with pads to slide between
the sections, place retract cables in the grooves in the
bottom pad plate, as the boom sections are slid together,
retract cables will pull thru these grooves, use
appropriate hardware and fasten pad plate to the bottom
plate of the 1st section.
48. Install a nut on the threaded ends of the 3/2/1 retract
cables, to keep the cable ends from pulling thru the
anchor as the sections are pushed together.
49. Push the 2nd-3rd-4th-5th and cylinder assembly inside
the 1st section, until it is within 36 in (90 cm) of full
insertion.
50. Install side wear pads with appropriate shims on the
front inside of the 1st section. Install upper spacer bar
