ake a slight change to the V10 bottom loading valve removal procedures on
the HEMTT tanker and save yourself time and money.
Start by eyeballing Step 5 of the removal procedure in Para 25-24 of TM 9
2320-279-20-3. There’s no need to remove 16
screws from inside the fuel tank as directed.
The valve will come off the tank easily
enough with the screws left in place, and you
can avoid damage to the screws and seal ring.
Don’t lose any screws, though. They aren’t
available separately, so if they are damaged or
lost, you’ll be buying a new seal ring for DS to
install.
A note will be added when the TM is up-
dated telling mechanics to replace the seal ring
only when the screws are broken, stripped, or
missing.
