HELP The Plot Sickens

It makes absolutely no sense and I'm grasping at straws here.

The last time the tractor "got hot" was when I was discing the other day. It went from center gauge 'normal' to pegged "hot" in the time it took me to turn around at the end of the field. It was okay going into the turn; when I looked down after dropping the disc back in the ground, the gauge was pegged hot.

I stick my head up under the hood this morning from the off-side and this is the first thing I see.

The thermocoupler tube has a 1" section of insulation worn off; the pictures don't show it but the metal on the hood is worn "shiney" and that bare therocouple tube is lying "hard against" the hood.

Even tho it isn't electrical, can I get lucky again?

It's NOT a "thermocoupler". There's no such word. ("Thermocouple" is a word, though".)

What you have on your heat gauge is a CAPILLARY TUBE.

Are you sure about your comment?

"It's NOT a "thermocoupler". There's no such word. ("Thermocouple" is a word, though".)"

Try telling that to an APG Troop (I'm Weapons) that works the F-16. Yes, I am not sure about a 966, but have worked on numerous 06, 56, 66, and a few 86 series tractors and can tell you that there is a (or what can be called) a thermo-coupler between the exhaust manifold and the muffler. The temperature that I was always concerned about was the water temp.

ther·mo·cou·ple

Pronunciation Key (thûrm-kpl)n.

A thermoelectric device used to measure temperatures accurately, especially one consisting of two dissimilar metals joined so that a potential difference generated between the points of contact is a measure of the temperature difference between the points.

"THERMOCOUPLER":

No entry found for thermocoupler.

Did you mean thermocouple?

But ya gotta take into consideration that I'm an old roughshod cowboy type who seldom ever talks to folks in a live situation.

The deer and jackrabbits don't care how I speak. They just acknowledge my comments by turning their backside. :>)

Naw, it usually takes me 'bout three or four stabs at things to get my point across and then it still comes out wrong. :>)

That's why I hang around you guys. You can understand things I can't. Yes, it runs right around the back side of that danged hot exhaust pipe.

Bless your collective hearts! :>)

Allan

That would explain why at times the darned thing would show cooler when I was travelin' "with the wind". At the end of the field, I would turn around and run facing "into the wind" and it would then show hot again.

Totally backaskwards to what a fella would think.

Thanks again,

Allan

That darned farm is a good 15 or 17 miles out in the country and I went out there with the idea of hooking up the trailer, loadin' the old pig up and bringin' her back here to my "good shop".

I should have pulled that sheet metal off the right side of the tractor and had a closer look. The theomocoupler does thread back around that pipe and I didn't pay any attention to it on that side. I'll bet you nailed it and that does make sense.

Wanted to ask you guys before I drug that thing clear back up here in the hills. Glad I did, 'cause I think you might be on to something. The gas expands to push 'er to hot, or so I've been told.

Thanks!

Allan

Re-routed it, put the tractor all back together and then used it for two hours hauling hay and the gauge never got over mid way. But, here again, I wasn't pullin' the tractor real hard either.

We'll see how it acts next week when I spring tooth that 50 acres of alfalfa ground. That ought to make 'er snort. :>)
