Re: Kohler K-series engine temperature
I have a multi meter that has a temperature reading setting. So I’ll use that next time I use the tractor.

Re: Kohler K-series engine temperature
How does it read temp ? Is there a thermo coupler attachment that goes with it ?

Yes. It has a lead from the meter about 2’ long. I’ve used it in many different things. And it reads correctly. Tested it the other day.DavidBarkey wrote: ↑Thu Jul 07, 2022 5:52 pmHow does it read temp ? Is there a thermo coupler attachment that goes with it ?

Re: Kohler K-series engine temperature
Report on the K321 that works without sign of stopping from overheating. Cut the grass for about 40 minutes. Temperature measured after I finished and stopped the engine, with the point and shoot IR thermometer, around the spark plug was between 226 and 248F (108 and 120C). On the side of the engine where the exhaust pipe exits the head was 266F (130C). On the other side of engine the head was around 235F (113C). To me this will be a base line. I'll try to repeat these measurements for this engine as well as for the 644 that seems to overheat.

Jumpins. That seems hot to me. I had to convert from C to F to get a better understanding. Low C temperatures around 30 or so and under I have an reasonable idea what the temperature is in F, but the higher C temperatures I have no clue.

Re: Kohler K-series engine temperature
Hotter around the exhaust part of the engine would be normal. That’s the area that the piston goes bad with the extra heat normally too. When you take a piston out for a ring job, the piston is scuffed up right in the area closest to the exhaust valve.
Just my experience.

Sorry, I was in a hurry and didn't convert. Edited my original post and added Fahrenheit.

No worries Eugen. Not hard to convert with the internet. When it works.

Re: Kohler K-series engine temperature
Did you happen to check the engine oil temperature Eugen ?

Re: Kohler K-series engine temperature
Unfortunately I cannot find my thermometer with the wire thermocouple so I have no means of measuring the oil temp. Hopefully I find that and measure it. It's only $17 on amazon but it bugs me to buy something just because I misplaced the one I have
