Boom
3.18 Model 6036 Legacy
Note: A hoist with a lifting capacity of 5000 lbs (2268 kg)
and two slings are required to remove the outer boom.
28. Place the slings around the outer boom. The slings
should be placed far enough apart on the outer
boom so the boom will balance when the boom lift/
lower cylinder mounting pins and pivot pins are
removed in the following steps.
29. Remove the capscrew (Fig. 3-40, 1) and elastic
locknut (2) holding the upper lift/lower cylinder pivot
pin (3) to the outer boom. Securely block the lift/
lower cylinder in position.
30. Remove the pivot pin (Fig. 3-40, 3) from the pin
mount by pulling the pin out. It may be necessary to
use an appropriate puller threaded into the pivot pin
to remove the pin. Discard the elastic locknut and
retain the capscrew.
31. Inspect the pivot pins (Fig. 3-40, 3) for nicks or
damage. Replace any damaged pins.
32. Repeat Steps 29-31 to disconnect the other lift/lower
cylinder.

Cylinder Pivot Pins

shims to ensure correct installation.
33. Remove the capscrews (Fig. 3-41, 1) and elastic
locknuts (2) holding the boom pivot pins (3) to the
frame. Use a brass punch and a rawhide hammer to
remove the pivot pins from the frame.
34. Remove the boom pivot pin (Fig. 3-41, 3) and shims (4).
35. Repeat Steps 33 and 34 to remove the pivot pin on
the other side of the boom.

36. Use the hoist to remove the outer boom from the
frame. Position the outer boom on a hard, flat
surface. Block up the boom as required to allow
removal of the extend cylinder from the underside of
the boom.
37. Withdraw the outer boom from the vehicle. Carefully
lower the outer boom onto suitable supports or to the
ground.
38. Inspect the boom and welds. Contact the JLG
Service Department or the local JLG Authorized
Service Center (ASC) if structural damage is
detected.
39. Inspect hoses, hardware, wear pads, mounting
points, chains and other components visible with the
outer boom removed. Replace if damaged.
