(Item 2) from the lock pins (Item 1) securing the rear carriage tilt
cylinders (Item 6) and boom hoist cylinders (Item 7) to the boom
(Item 8). Remove four (4) lock pins from the pivot pins (Items 4 and 5).
CAUTION: Make sure each cylinder is fully supported so it does not fall
and cause personal or equipment damage when it is being
removed.

slide hammer puller threaded into the pivot pin (Item 4) to remove the

cylinder to swing down and away from the boom.
CAUTION: Use suitable blocking to support the cylinders and prevent
damage to the surrounding structure.
