First real use of Mep-803 | Praises and problems (albeit little)

[Guyfang]

I was out of the net.

The Army is strange. Some gen sets have ALL the info, gen set and engine both, in one TM. Others, not. That's why when you look at a TM number like, TM 9-2815- anything, you KNOW its an engine TM. Any TM that starts with TM 9-6115-anything, you KNOW it is a Generator set TM. Its very confusing for people who were not in the military or in a maintenance field. One reason this is so, is because the engine might be used in several different pieces of equipment. And not always gen sets. So, to save money, they break the engine out of the total package and print it separately.

Okay, apologies in advanced for my stupidity here. I feel like if you can walk me through this I should have a good understanding of how to navigate the TM's.

I'm in 9-2815-253-24.

on 3-2 (troubleshooting table) i see: Low Oil Pressure ....................................................................................................................................................3-5 \

flip to 3-5 and see:
9. LOW OIL PRESSURE.
Step 1. Check for improper grade of oil.
a. Refer to end item lubrication order. If proper grade of oil, do Step 2.
b. If improper grade of oil. Refer to paragraph 3-20.1 and change oil and filter.
Step 2. Check for engine running hot.
a. Refer to Engine Overheating, Malfunction 7, in this table.
b. If not running hot, repair or replace engine.

*insert joke about replacing engine and oil pressure still low*

What am I missing here?

Just to confirm your question was answered directly (it was over the replies that followed), but that's the diagnosis steps for the engine only. If you take the sender and all other accessories out of the picture... its a mechanical oil pump. If you have pressure issues in this engine, with that pump... the military knows its an internal concern.

Now with the steps from the genset book which I provided, its highlighting the accessory test steps for that platform. Both books can be used together if needed, but as you see... the info sets are different. Both are GOOD sets of info, but its a whole lot less likely that there is an oil pump concern in this piece of equipment, than a failing sender or gauge.

Does that help make it clearer?

Yes this clear now! Thanks for spelling it out explicitly.

Its called learning by doing!

That is why I like my 002 and 003's, Mechanical oil pressure gauges! My oil pressure safety switches have failed on all of my sets. Electronics are a royal pain.
