Studs,
NSN
are now available to replace the four
bolts that currently secure the fuel
nozzle to the combustor cover. The
studs help align and hold the fuel
nozzle in place during installation.
The studs also work with both the
old and new conFgurations.
Screw the studs into the combustor
cover. Drop the fuel nozzle in place
and add a ±at washer, NSN 5310-01-
352-9593, and a self-locking, silver-
plated nut, NSN 5310-00-844-4872,
to the top of each stud to secure the
fuel nozzle. Torque the nuts to 90-
100 lb-in.
C
rewmen, you wouldn’t consider going outside without your head cover. You should
feel the same way about the ²BCB2 antenna on your M1-series tank.
The antenna, NSN 5985-01-551-7316, is protected by a plastic cap. Too
often, stray limbs and brush will break or knock off the cap, leaving the antenna
unprotected. Since it’s located on top of the tank, you might not notice until the
antenna is damaged.
Take a quick look at the antenna before, during and after operations. If the cap is
missing, replace it with NSN 5340-01-541-0758.
Since the working threads on the studs are now in a
cooler location (300°² at the top of the studs vs. 700°²
inside the combustor cover), the threads are less likely to
seize during semi-annual maintenance.
The next time you need to remove and reinstall the fuel
nozzle, the ±at washers can be reused. So can the original
self-locking nuts as long as the self-locking feature is still
in good shape. If the nuts can be Fnger-tightened, the self-
locking feature is worn out and the nuts must be replaced.
Make a note until the fuel nozzle assembly replacement
procedures on Pages 5-30 and 5-31 of TM 9-2350-264-
20-1-3 (Mar 03 w/Ch 4, Jun 09) and WP 0288 of TM
