Installation
1. If installing a new cylinder, test fit the retaining pins
that secure the jib telescope rod to the jib fly boom
to ensure they fit properly. Apply an anti-seize com-
pound to the attachment holes in the cylinder rod.
2. Lift the cylinder into place, adjusting the lifting
device as necessary to maintain balance.
3. Fasten the cylinder barrel to the jib base boom with
the attaching bolts. Do not tighten the bolts at this
time.
4. Connect the hydraulic hoses to the cylinder as
tagged during removal.
5. Lower the jib enough to enable easier access to the
attachment holes in the jib fly boom.
6. Extend the cylinder enough to align the attachment
holes in the jib fly boom with those in the end of the
cylinder rod.
7. Install the retaining pins and secure them in place
with the retaining rings.
8. Apply JLG Threadlocker P/N 0100011 to the bolts
securing the cylinder barrel to the jib base boom
and torque the bolts to 95 ft.lbs. (130 Nm).
9. Function check the cylinder to ensure it operates
properly and there is no leakage.
