TRACK AND SUSPENSION
6. If studs are not available, or old studs
cannot be removed. Weld the hub on as shown.
7. Use the remaining parts of studs to
align hub to final drive and weld in
place with a continuous bead.
8. Reinstall track assembly.
9. Record BDAR action taken. When
the mission is completed, as soon
as practicable, repair tank using
standard maintenance procedures.
9-11. SUPPORT ROLLER DAMAGED
a. Return rollers keep the track
from sagging as it moves from the
sprocket to the idler and are
necessary to keep the track from
being thrown caused by hitting
the hull center section. With
no rollers, tank operation should
be restricted to self evacuation.
b. Return roller damage that
would provide jagged edges which
could snag the track must
be corrected. A roller that will not turn is less of a problem than a bare stub shaft
which would catch the track and break or throw it. F-or rollers that will not turn,
disassemble and clean. The bearings may be damaged and need replacing.
If the roller is broken attempt to turn so that the smoothest segment is up and provides
a sliding surface for the track.
Weld the bearing and roller hub in this position so they
will not turn.
Other Options:
l When the roller is totally missing or cannot be made to provide a smooth sliding
surface, it will be necessary to cut off the hub with a torch.
