he good news is that eight Bradley line replaceable units (LRU) are being felded that
are covered by warranty at the wholesale level. That means iF they quit working, you can
turn them in through your normal supply channels and receive credit For a new LRU.
The bad news is that many Bradley units don’t realize that. Currently, a large percent oF
the LRUs being turned in have broken seals and thus voided warranties. This results in higher
prices For the LRUs, a higher number oF back orders, and a longer repair turnaround.
Part oF the problem is that the old LRUs could be
repaired at unit level, so repairmen assume the new ones
can be repaired there, too.
But it’s easy to spot the new LRUs. They have tamper-
resistant seals that say “CPU TECH” or “WARRANTED ITEM,
WARRANTY IS VOID I± SEAL IS BROKEN. RECOVERABLE
ITEM–NO REPAIR AUTHORIZED.” Removing the LRU cover
breaks the seal–and voids the warranty.
The LRUs covered by warranty should be turned in For
repair through normal supply channels. The old LRUs can
still be fxed by feld maintenance.
Thoroughly sweeping out the inside of the
Bradley should be your Frst step. Be especially
careful to clean underneath the gunner’s seat
where the main diagnostic connections are. Dirt
can foul the connectors, which hurts the accuracy
of the tests.
There’s
not much
room
underneath
the
gunner’s
seat
to
connect
the
diagnostic
equipment, so remove anything that has been
stored there, like TMs or Feld gear.
If you’ve put a screen over the periscope face,
remove it before testing. The screen makes it
difFcult to hook up diagnostics. ±or the same
reason, remove the M242’s feed tray.
