15 Tag, disconnect and plug the 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.

the center point of the boom.
17 Attach a similar lifting device to the primary
boom lift cylinder.
18 Using the overhead crane, raise the primary
boom to a horizontal position.

boom to support the boom lift cylinder.
20 Remove the pin retaining fasteners from the
primary boom lift cylinder rod-end pin. Use a

cylinder onto support blocks. Protect the
cylinder rod from damage.

primary boom.
24 Remove the limit switch cam mounting
fastener (if equipped).

primary boom pivot pin.
26 Use a soft metal drift to remove the primary
boom pivot pin. Carefully remove the boom

overhead crane is not properly
attached, the boom could
become unbalanced and fall
when it is removed from the
machine.
