1862 hot

Mr Bob · #1 10-27-2023, 01:37 PM

Hello fellow members. I used my 1862 to cut grass and leaves. I had cleaned around everything I could get to on the tractor but when I finished the front of hood was extremely hot. Would almost burn you hand if you pressed it on hood hard and left it for less than 30 seconds. My 1862 has a 6" pto pulley and I can not find the air adjustment slots on it. It will not stay running unless I hold the new pto switch up in the start position. Think I need a new relay? All help appreciated and have a great day.

Do you still have the top muffler shield installed? Is it running lean? That will make it run hotter too.

CubDeiselFan. The top muffler shield is in place. Don't believe it is running lean but will check it over the weekend. Thanks for the response and have a great day.

Hey Bob. More then once I have found myself having to hold the PTO
switch up to keep it engaged on my 1862. Each time I traced it back to a
seat switch. Could be any switch in the start circuit messing with it.
I think the owners manual has some pretty good info on setting the
air gap. I will look at it tomorrow and see if I can be more help.
Do you think it was PTO that was getting hot or the engine?

Hi Ken. Don't really know which it was. After one hour in the seat I was pretty tired so I blew the dust off and put it in the garage. The previous owner has the seat Jerry rigged. He has big clips that hold the seat down tight to it's mounting frame. I am going to take the clips out and disconnect the seat switch to see if that cures it. I have always been able to adjust the air gap but this 6" pto seems different. My back is bad and It is hard for me to get my head in there to see what is what. Will give it another try next week. Thanks so much for the info and have a great day.

Morning Bob Here is a picture of the air adjustment slots on the 1862
PTO. There are 3 slots. Manual calls for .017 gap in the slots. They adjust
with the nut right next to the slot in the picture.. I hope it doesn't beat you
up to bad. Aint nothing easy with a lousy back. I know the routine well.

The electrical latching relay setup on the PTO for the Cyclops tractors is a little more complicated and can trip people up. Your two main control devices are the seat switches and reverse switch. If either of those controls fail, the relay will not stay latched. In the Start position of the PTO switch, it bypasses temporarily those controls.

If you are still struggling to figure this out, this video may help in the electrical diagnosis. We did a video series on the electrical system of an 1882, which is almost identical to your 1862.

Just wondering...

There is a small heat shield under the larger heat shield that is mounted just over the PTO. The purpose is to divert heat from the engine so it doesn't fry the PTO. Is this PTO shield in place on your tractor? This could be contributing to the problem. Most likely though, the jury rigged seat switch is the culprit.

Thanks to all that replied and Merry Christmas to all. Still having trouble with my back and have not been able to check the things out that was mentioned. Maybe I am getting too old. Am going to try to have a look and see if I find anything after Christmas. Thanks again for replying and have a great day.

I assume that has the Kohler Command engine. The owners manual says to pull the shrouds once a year and clean out the cooling fins.

You can't really do this with the engine in the tractor. It's not that hard to remove - fuel line, wiring harness on starter and rectifier, PTO belt, 4 bolts. An engine hoist or a strong neighbor. Set it on an outdoor table, tape or plug the openings, and pressure wash it. Or set it in your pickup bed/trailer and go to the coin-op car wash.

In my experience few owners do this. As the engines get some time on them and leak a little oil, it becomes an annual imperative. My 1864 is waiting on me to get around to it.
