MEP-803A Need p/n for coolant high temperature switch

[tom250e]

Hi folks!
I'm new to the forums and have found some great information here. I have also downloaded the TMs for the 803 and after searching through them am still unable to find a part number for this switch. I have read some posts that refer to an NSN cross reference list but am unable to locate it in the TMs I have (TM9-6115-641-24, TM 9-6115-642-10).

Being a noobie and all I have probably overlooked the info I need; so if one of you gents would kindly point me in the right direction I would very much appreciate it.

Thanks!

Welcome to the outfit Tom!

There are several guys on here that are really sharp on "making power".
Chances are the "military name" for it is different than how you are searching in the TM's
I did a quick search myself and came up empty...

I imagine the guys will come along after dinner and get you started down the right path.

The NSN number of it is 5930-01-378-6882 which is PN 88-22203.
Other PN's that are the same are 8037122 & TM-512C3-225N0

There are some on ebay. Search the NSN number. $15 shipped.

Just search the phrase 'INDEX Thermostatic Switch 8037122' and you will find what you want.

And the price is dang reasonable...
Especially with me knowing nothing other than the cost.
$11 to $24 to solve the problem is a downright good.

Thanks guys! I've got one on order!

I am curious though, did I overlook something or is the part number info in a different source than the TMs? Just trying to learn...

There are many ways to ascertain part numbers for items. A good trick in finding parts, is to dump the NSN in question into parttarget.com. An example with this switch:

https://www.parttarget.com/5930-01-378-6882_5930013786882_8037122.html/-d08cd3fe-050d-43f1-9de1-7837c2abf26e?searchtext=5930-01-378-6882&searchoption=sku&originalsearchtext=5930-01-378-6882

It's in the -24P TM. The engine sensors are later in the manual than the up front electrical stuff.
You can search the 88-22203 in the TM. It'll show you where in the TM its shown.

For sure - and the right name to search with is the real magic.

Trucks are more my thing.

I kept searching for a rubber "bushing" and I never could find it. Going through the TM page by page, I finally found "cab support" to be the proper term for the part I was hunting for... It gets better the more you talk to others and the more you rummage those BORING books. They darn sure aren't very entertaining!

Take a look at TM9-6115-642-24P. As you page through it, you should notice, it deals with the Generator set. By and large not the engine. There is a separate TM for the engine, If you look in TM9-2815-253-24P, thats the engine book. You will look to no avail in the 253-24P for the Temp Switch. So that tells you this engine can be used in other applications. And that means you always look to the back part of the Gen Set book, 642-24P. In the table of contents, you will find a heading listed:

Group 09 Engine Accessories ......................................................................................................
Frequency Adjust Cable ......................................................................................... 19-1 19
Engine Accessories ............................................................................................... 20-1 20

In the ENGINE ACCESSORIES, is listed all the special gizmo's that are specific to this generator application.

That REALLY helped clarify things for me! Thank you for sharing your knowedge and experience!!!
