5.2-7 Arm Bearings –
Removal and Installation
The following procedure can be performed with the arms
in place and the Clamp mounted on the truck.
NOTE: Normally only the long bearing segments need to
be replaced due to wear. If inspection reveals wear on
the short bearing segments, replace them also.
IMPORTANT: Remove and replace the bearings from the
rod end of each cylinder. Start at the uppermost arm
bearing as shown and work down, replacing a bearing
each time to keep the Clamp arms fully supported.
1 Raise the Clamp off the floor and close the arms.
2 Remove the arm bearing retainer.
3 Slowly open the arms to drag the top bearing out of
the bearing way.
4 If the bearings are tight, close the arms and attach
clamp-type pliers to the end of the bearing. Slowly
open the arms to drag the bearing out.
5 Close the arms. Using a 1/8 to 3/16-in. (3 to 5 mm)
thick piece of rod or flat stock, drive the shorter
bearing segment out of the bearing way as the arms
are slowly opened.
6 Open the arms to the mid-way position.
WARNING: Make sure that a safety person
is at the truck controls at all times if this
maintenance procedure is done with the
truck running.
7 Install new bearing segments. Slowly close the arms to
drag the bearing segments into the bearing way.
8 Remove and replace the bottom bearing set on the
same arm.
9 Install the arm bearing retainer. Apply Loctite 242
(Blue) to the capscrew threads and tighten the cap-
screw to 15 ft.-lbs. (20 Nm).
10 Replace the remaining arm bearings by following the
same procedure as in Steps 2 through 9.
Lubricate the bearings with light oil or grease. Cycle
the arms and check for freedom of movement.
