Shutter control valve assembly thermostat

[kilerian]

Does anyone have a cross reference number for the this thermostat. It inside the the shutter control valve assembly on the bottom of the radiator on my MEP 006A generator. I cannot seen to find anything. The numbers on it are:
CA30029 170-185
137-1 C 01

Any help would be appreciated

I had the one on my 004 fail. I ended up making a new fitting and using a linear actuator for the shutter

I'm hoping to not have to LOL.

I can't blame you. It was a pain in the ass

I think that is called a thermal actuator, or a wax motor. E.g.

Thermal Actuators - Fulton Bellows

The Fulton version looks somewhat similar to yours.

Variations are used in the HVAC industry, and greenhouses (though those are usually lower temperature ranges).

I suspect that the 170-185 in the part number is the temperature range, but I have no idea who made yours as I couldn't surface a matching item with the CA30029 part prefix. Sorry.

All the best,

thanks. ill start looking at those and see it i can find anything. I might call them in the AM also.

Good luck!

What is the thread size and length on yours? I found this one on eBay, but I am a bit the concerned that it is too hot for your application, but perhaps they can supply it in a different temperature range?

Pardon Our Interruption...

They also sell a $14 version, no threads, no specifications...

@Guyfang Thanks for that. I am not pulling up Cadillac as a source, but I do see a variety of actuators made by Evans Tempcon, (Now known as Comfort Air GR (for Grand Rapids, MI?)

I called Delks army navy. they actually have a few used ones. He is going to check them to make sure they still work and Ill call him Monday.

This would be a bit high for the 15 KW.

This is where I put on my teachers hat. I will tell you how to find out who the SUPPLIER of a part is to the military. Keep in mind that SUPPLIER and MANUFACTURER, are horses of a different color. Very often they are one and the same. But not always.

Open up the -24P to SECTION I, INTRODUCTION, page # 1. Start reading. Its not long. This is very important information, that only Motor Sargent's and CWO's read. It decodes all the information on the -24P pages you have never heard of.

Lets look at the place that shows you who supplied the item to the military. That would be in this TM, the REF Number & MFR Code. The Ref number is the part number. The MFR Code, (In some other TM's this will be called the CAGEC Code or in newer TM's, FSCM Code) This is the code representing who supplied the part. In the older TM's, there was actually a list in the TM of MFG codes, with the contact information for the companies. Go to your search engine and type in MFR, (or CAGEC code or FSCM) and the number 96309. It comes right up with:


I would also suggest reading about UOC codes. Usable On Code. This code tells you what part fits what model of the generator set you might have. If there is no UOC, then that part fits ALL models of that gen set. If there is a UOC, the list in the front of the TM will tell you what gen set that part is for. Putting a 400 hertz part into a 60 hertz gen set, is not advisable. It can lead to the loss of valuable smoke, and money.

All these years reading the manuals and I never put those dots together!!! Always learning, always learning. Thanks Guyfang.

Your more than welcome. The UOC is another thing that few know about. It can save you big money. Here is a good story of the UOC causing BIG problems. The 30 KW Mep-806A. I think the TM's are STILL wrong, I have to look. The short story is, the UOC for the main generator was wrong. I went to a unit on request, WOPA, request. The gen set had not worked right in the last two years. The unit was a DS, (Direct Support) unit. They asked me to take a look. No A.C. Output. The A-C. Meter showed no output. After an hour or so, I had it. I had taken my DMM and checked the 120 volt outlet, and had gotten an "Over volt" reading. How could that be? So I checked at the load terminals, Over voltage, on my DMM. I pulled the rear cover off the set, and found a 416 volt, 400 hertz main gen installed on a 60 hertz gen set. The A.C. output meter could not read that high, and so showed no output. I put it back together and when the boys came back from lunch, we "Discussed it." I was rubbing it in, hard. The CWO told me that they had put in TWO main gens, over the last two years! So we drug out the -24P, and compared the part numbers in the TM, against the main generator. The UOC was reversed. 10-12 thousand bucks of parts changed over the course of two years, and all because of a typo.

You will find issues with UOC on the 3, 5, 10, 30, 60, 100, and 200KW gen sets in the TQG line. I made parts lists and sent in 2028s, and eventually some were fixed, but the parts lists resolved most issues in the active field. The ARMY's FEDLOG program assisted in finding these as I looked up every part on lists I made. Found issues in this too as even FEDLOG was incorrect. I also made an engine and main gen paper and handed out about 20,000 DVDs in my 20 years. As the manual section gets updated, some of these will be in there. I have updates that are not in the manuals on these parts lists, found only in FEDLOG and engineer correspondences. Please remember these are older gen sets. In the day, the clerks typing papers on this were unaware of what they were typing, Knew nothing about gen sets, paid very little, and were usually worried about what was on General Hospital on TV than what they were typing. You will also find issues in the AMMPS manuals, but this was due to parts changing, and engineers working on papers and never actually seeing a gen set, or ever did any mechanical activities. Reality folks, true, but reality.
