BOOM COMPONENTS
14 Using auxiliary power, activate the boom down
function so the cylinder will retract. Retract the
cylinder just enough until the rod end of the
cylinder will clear the mounting bracket on the
boom. Turn the machine off.
Crushing hazard. The boom lift
cylinder could fall if not properly
supported and secured to the
lifting device.
15 Using the overhead crane, carefully lower the
boom lift cylinder and allow it to rest on the
boom rest pad. Protect the cylinder rod from
damage.
16 Remove the boom end cover retaining
fasteners and remove the cover.
17 Tag, disconnect and plug the boom extension
cylinder hydraulic hoses. Cap the fittings on the
cylinder.
Bodily injury hazard. Spraying
hydraulic oil can penetrate and
burn skin. Loosen hydraulic
connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to
squirt or spray.
18 Tag and disconnect the electrical connector for
the cable break limit switch.
19 Tag and disconnect all boom wire harness
electrical connectors located at the pivot end of
the boom.
20 Support the platform leveling master cylinder.
Remove the master cylinder rod-end pivot pin
retaining fasteners. Place a rod through the pin
and twist to remove. Carefully lower the master
cylinder down.
21 Tag, disconnect and plug the hydraulic hoses
from the bulkhead fittings at the pivot end of the
boom. Cap the bulkhead fittings.
Bodily injury hazard. Spraying
hydraulic oil can penetrate and
burn skin. Loosen hydraulic
connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to
squirt or spray.
22 Remove the external snap rings from both boom
pivot pins at the short and long link arms. Do
not remove the pins.
