Boom & Jib Section 5 – Procedures
24. Bring the new cylinder over to the riser and orient
it so the rod end is up, and the fitting ports are
facing side-to-side. Lift it in through the gap in
the riser, then rotate it so the lower port is facing
away from you, and set it in place.
25. Remove the wooden block, and bring the riser
down until the cylinder’s lower pin is accessible
for reinstallation.
26. Use a rubber mallet to tap in the original lower
cylinder pin. Apply Loctite 242 to the original
retaining bolt, and reinstall the bolt.
27. Lower the riser all of the way down, then raise
it back up slightly to take the pressure off of the
temporary knuckle pins.
28. Remove the bolt and washer holding one of the
temporary pins, and remove the pin.
29. Set the original pin back in place and start
tapping it in with a mallet, making sure the shims
between the knuckle and arm are aligned while
tapping the pin in.
30. Use a large adjustable wrench on the pin flange
to align the retaining screw holes on the pin and
knuckle, and finish tapping the pin in. Apply
Loctite 242 to the original retaining bolt, and
reinstall the bolt and washer.
31. Repeat the process with the other pin, adjusting
the boom as needed with the lifting device to
assist in alignment.
32. Place an oil pan and/or rags inside the riser
under the cylinder to catch leaking oil.
