Boom
Note: ALWAYS replace elastic locknuts with new elastic
locknuts to help ensure proper fastening.
25. Coat the upper pivot pin (17) with anti-seize
compound. Insert the pin through the rod end of the
Slave cylinder. If necessary, use a rawhide hammer
to install the upper pivot pin. Use a tapered punch to
align the capscrew hole in the pin with the mounting
tabs on the cylinder. Secure the upper pivot pin in
place with the capscrew (18), saved, and a new
elastic locknut (19). Tighten the elastic locknut
securely.
26. Repeat Steps 22 thru 25 to install the other Slave
cylinder to the other side of the outer boom.
27. Install the boom proximity sensor (20) on the right
side mounting plate. With the boom properly
shimmed, position the boom assembly all the way to
the right side.
28. Insert the boom proximity sensor (20) through the
hole in the right side mounting plate (21). Install the
jam nut (22), saved, onto the boom proximity sensor
on the inside of the plate. Adjust the inner and outer
jam nuts on the boom proximity sensor until the
gap (23) between the sensor and the boom is .12"
(3 mm). Torque the inside jam nut to 36 lb-in
(4,1 Nm), to hold the boom proximity sensor in
position.
29. Assemble the extend tube (24) to the extend port 90°
elbow (25) on the Extend/Retract cylinder (26) and
the inside bulkhead fitting (27) on the right side of
the outer boom. Hand-tighten the tube fitting to the
90° elbow. Reposition the tube as needed to align
the other end of the tube with the bulkhead fitting.
Tighten the tube end at the bulkhead fitting and then
tighten the tube end at the 90° elbow.
30. Assemble the retract tube (28) to the retract port 90°
elbow (29) on the Extend/Retract cylinder (26) and
the outside bulkhead fitting (30) on the right side of
the outer boom. Hand-tighten the tube fitting to the
90° elbow. Reposition the tube as needed to align
the other end of the tube with the bulkhead fitting.
Tighten the tube end at the bulkhead fitting and then
tighten the tube end at the 90° elbow.
