MEP002 mystical Shutter assembly

[CDR]

My shutter door wont open. This seem to be what controls it. I have no idea what this is suppose to do and if it broken or not? No chance anyone has a spare one?

thats it all apart I cleaned it and it still doesn't work

from upper shutter. Adjust ball joint until upper
shutter closes tightly on lower shutter when lower
shutter is held closed. Re-attach ball joint to upper
shutter.
(2) Thermo Unit be figure 4-6). With Generator
Set at 70° F, (21°C) loosen thermo unit guide mounting
screws, the mounting holes in the shutter box are
slotted. Slide the assembly to a position where the
thermo unit plunger rests on roll pins with shutters
closed. Tighten mounting screws.

The piece that actually moves the shutters in and out works just like the thermostat in your car. You should be able to test it in some warm/hot oil and see if it moves. If so, then it is an installation/adjustment issue. honestly, you're the first person who I've heard of that one of these has actually failed. Most people say they were bad, but when they ran the generator fully loaded and build up enough heat, the shutters actually opened. It does take quite a bit of heat to open them.

Mine open but very little. The most I have seen is when it was in the 90's and they were opened about 1/2 inch. Usually it is hardly noticeble.

I have several. If you need one, PM me.

Ran it full load for an hour oil temps where reaching 240 degrees and it was about 95 in the area I was running it. I tried adjusting it with no luck

Emailed you thanks!

So I guess all the "hard grease" I scraped out of it was wax... Oops
"The secret of the thermostat lies in the small cylinder located on the engine-side of the device. This cylinder is filled with a wax that begins to melt at perhaps 180 degrees F (different thermostats open at different temperatures, but 180 F/82 C is a common temperature). A rod connected to the valve presses into this wax. When the wax melts, it expands significantly and pushes the rod out of the cylinder, opening the valve. If you have read How Thermometers Work and done the experiment with the bottle and the straw, you have seen the same process in action. The wax happens to expand a good bit more because it is changing from a solid to a liquid in addition to expanding from the heat."

I'm getting some education

Yeah, I don't think that was hard grease you were scraping away. Well, you have the privilege of being the first person I've heard of to have one of these actually fail. Good luck getting it back together.

intalled a new thermistate and success! It now works!

 

[Speddmon]

Awesome, good work!

I have had some that open in 5 minutes and some just creak open after an 30. Think the amount of wax in there to expand decreases or becomes ineffective over time or something. I could use a few nos ones hmmm
