Bearing Replacement
These bearings usually wear down in pairs,
either both front or both back. Even if only
one bearing shows signs of excessive wear,
replacement should still be done in pairs.
Required Tools
13 mm metric wrench, 5 mm metric
Allen key, 7/16” wrench, 3/16” Allen
key, Phillips screwdriver, clean cloth
Perform only when the unit is OFF
with power disconnected.
Turn power OFF at the main disconnect
switch.
Remove the two metric Allen screws
which secure the spread clamp/air cylin-
der to the linear bearing assembly block
(Figure 7-25, A).
Remove the two bolts (Figure 7-25,
B) which secure e-chain to the bearing
block.
Remove the end screw from the appropri-
ate spreader rail at the center of the unit
(Figure 7-26).
Raise the rail slightly and slide the bear-
ing block off the rail. Place it on a work
table.
Remove the screws which secure the worn
bearings and remove them from the block.
Be sure to keep track of the spacer.
Use a clean cloth to wipe down the bearing
block and the spacers.
Carefully reposition the spacers (Figure
7-27).
Insert the new bearings, making sure not
to move the spacer out of position.
