861 temperature gauge acting funny-replacement question

The temp gauge on my 861 seems to be acting a bit funny. It will go up to red then drop back to yellow and then it does eventually settle in the green. If I do have to replace it where does the sending unit thatís attached to the gauge go to read the temp?

Agreed,, the little hole in the flange is critical to get the thermostat to open at the correct temperature. It also lets air out when filling so that it wont trap an air bubble, or in this case a cold water slug. By letting a tiny bit of water flow, the thermostat will get warm water to the bulb much faster, open on time, and regulate temps better with out the ping pong effect.
Some thermostats come with the little hole, some do not. Some tractors are more critical and need the hole, some less so depending on the location of the thermostat. The ford 2000 and 3000 gas tractors were the worst due to the manifold design.

Buying a new thermostat will probably do the same thing since most new thermostats open backwards, backing against water pump flow .Drill a 1/8" hole in the thermostat next to the mounting flange to serve as a small bypass or try an get a thermostat that opens on an "axle", like a positive water valve

Temperature gauge gradually rising into the green and staying there also shows you if a thermostat is working normally. I'd replace the thermostat before it fails to open at all and blows or burns something up.

Sure sounds like thermostat.

Yep! I think you're seeing a finnicky thermostat. Doesn't open when it should, then stays open to long. I like the infrared heat gun idea to find out exactly what's happening.

That said: the original temperature gauge on your 861 is a capillary tube operation. The end of the tube, or sensor bulb, is in the right rear upper corner of the head.

Could be the thermostat. Get an infrared thermometer and check temps while gauge jumps.

leave it alone. both of my 960 did the same thing. if anything I would maybe change the thermostat but I would leave it alone. it shows you that the thermostat is opening which is good to know.

Today's Featured Article - Box Plow Blues - by Tom Schwarz. One of the first implements most tractor owners obtain is the box plow. For very little money, this piece of equipment promises to plow and flatten any hill or vale on your ranch road or farm. At least that's what I thought! As simple as a box plow appears, it can be rather challenging to make work correctly. In our sandy soils of Florida, traction is king. You can never have wide enough tires or heavy enough weights to get all the traction you want Ö unless you own a monster tractor. U ... [Read Article]
