Dear Half-Mast,
Item 1 in Fig 17 of the 30-kW TQG engine technical manual, TM 9-2815-
259-24P, gives the part number for the oil dipstick as RE69243. In the
part number index, this crosses to NSN 6680-01-470-3952.
We ordered this dipstick and when it arrived, it wasn’t the same as the
one it replaced. This dipstick was one-sided. The one it replaced was two-
sided with measurements for a hot and a cold oil check.
So, did supply send the wrong dipstick or has there been a change where
a two-sided dipstick is no longer required?
SGT R.T.
Dear Sergeant R.T.,
Thanks for the great question. When you’re talking preventive maintenance, it
doesn’t get any sweeter than a discussion about engine oil dipsticks.
Ignore the part number and NSN shown for the engine oil dipstick in this TM
for the 30-kW TQG and in TM 9-2815-260-24P for the 60-kW TQG. This is the
wrong dipstick for these John Deere diesel engines that need both a hot and cold
oil check.
The correct, two-sided dipstick is part number RE501288. However, there is a
problem. This dipstick is not in the supply system. In order to get it through the
system, you will need to make a part number request using DD Form 1348-6.
Enter in the REMARKS block that there is no NSN for this part and that the part
must be ordered directly from John Deere.
Or, you can simply order it yourself from the John Deere military sales website:
fedmilitarysales/parts.html
Once at the website click on the
Parts Catalog
. Once there, enter part number
RE501288 into the
Search
engine. From that page, you’ll be able to order the
dipstick. You’ll need to register and establish a password to complete your order.
Eventually, DLA will clear the supply shelves of the wrong dipstick for this
engine and put the correct dipstick on the shelves. When it happens, we’ll let
you know.
Y
our day is going fne and the world looks
rosy when out-oF-the-blue your big TQG
shows an error code oF 901 in the digital
voltage regulator (DVR) display.
You panic because you know that code
represents something nasty–a DVR Memory
±ailure Severe ±ault! Time to get a new
DVR, you think, as your perFect day comes
to an end.
But wait!
It could be a
mistake. It has been
known to happen.
Try to change
and store a new
parameter value in
the DVR.
±ollow your TM.
Did it work?
No?
Then try this:
1.
Shut oFF the power to the DVR and take the generator oFfline.
2.
Press and hold all three Front panel
buttons–Function arrow keys–at the same
time.
3.
While holding the buttons down, turn the
power on. Hold the buttons down For a Few
more seconds, then release.
4.
The DVR will boot up and return to the
Factory-installed deFault settings.
5.
Reprogram the DVR like it says in
your TM to the settings you need For your
operation.
Did the 901 Fault go away?
It did? Great! The world is rosy and the sky is clear again.
It didn’t? It popped back up? Sorry, your day is still cloudy and you’ll have to
replace the DVR.
