Secondary Boom Components
38 Z-34/22 Bi-Energy Part No. 1268515
4 From the bottom side of the cylinder, remove
the retaining fasteners from the secondary
boom lift cylinder barrel-end pivot pins.
5 Use a slide hammer to remove the barrel-end
pins (access the pins from the access holes in
the bulkheads, one on each side).
6 Remove the pin retaining fastener from the
secondary boom lift cylinder rod-end pivot pin.
Then use a soft metal drift to remove the pin.
7 Carefully lower the cylinder down through the
secondary boom, enough to access the
hydraulic hoses. Do not pinch the hoses.
Component damage hazard.
Hoses can be damaged if they
are kinked or pinched.
8 Tag, disconnect and plug the hydraulic hoses
from the secondary boom lift cylinder. 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.
9 Carefully remove the cylinder by raising it
through the top of the secondary boom using
the overhead crane.
Crushing hazard. The secondary
boom lift cylinder could become
unbalanced and fall when
removed from the machine if not
properly supported by the
overhead crane.
