What do your water temps look like?

[RobJ]

Attached is the pic of my gauges. I added all but the tack/hour gauge as the L2500 is a no frills tractor. But the temp gauge is a Kubota brand for this model. I believe my thermostat is stuck (takes a long time to warm up on the gauge) and I have one but haven't changed it yet. Since it's probably stuck open the water may be passing through the radiator to fast. I'm getting a little weeping from the overflow tube. Fan/belt area all ok.

Thanks,
Rob

Mine barely moves past 1/3 from the left. Gets there in about 5 minutes and stays there pretty much whether it is idling or I'm working it hard.

I would guess that your thermostat is probably stuck open also.

Rob, anytime the gauge on my B2710 went that high, I knew it was time to stop and clean the debris off the front of the radiator. Normally, it never went higher than a third of the way up.

Like the others, the temp gauge on my L4200 barely moves off of cold - maybe to an 1/8th at best.

Pushing my B7800 with mowing, snowblowing or FEL work, I have never got the temp above the "C" on the gauge.

 

[RobJ]

Hmm, barley off the C. That almost sounds to cold or something. I would think somewhere in the 1/3rd range. But I've never worked it in snow. /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif It was in the 90's and I was running the FM when that pic was taken.

Time to take the time and change out the thermostat I guess.

Thanks for the replies.

No snow. Oh what fun you have missed!
In the winter, I replace the rad screen with a corrugated plastic sheet with a 6" square hole cut in the center of it. Even with that, I have to work the tractor hard to get more than lukewarm air from the cab heater.

My L4200 runs around this temp (see picture) year round… I do replace the screen with solid during the coldest part of winter (keeps heater very hot)… During the summer it may run a little warmer when over 100 degrees out and working hard with air conditioner running /forums/images/graemlins/cool.gif.

Well a little follow up. I pull the thermostat and it was for sure stuck. Just barely open. I almost could not operate it with a screwdriver. I replaced the unit and the tractor was still running hot, about the same. I stopped mowing (not a heavy load, 5' FM) blew out, flushed out the radiator fins, all clear. No change, pull the upper hose and noticed just a trickle of water. Needing to finish I pull the complete thermostat and ran it again. Temp slowly built up the the attached pic (the inset picture is the old one). Then it maintained its position. I didn't have time to pull the uppse hose again and check for flow, but I just flushed the radiator and it was clear. But for now the radiator overflow hose is not weeping. Around here with the heat and the lack of much of a winter the thermostat isn;t as important, but I'll work on it later...

I have the L2350 . Only have a tach/hour meter. I would like to add the oil & water temp gauge. Especially the temp gauge. I wouldn't have a problem mounting them but where do you connect the water thermocouple on the engine and also the oil pressure sensor ? Pic's would be really helpful !

WEll for the life of me I can't locate the pictures of the stuff, so I'll describe....

Oil Pressure - just a regular auto parts oil pressure gauge. Your tractor is like mine, it does have a oil pressure idiot light, you can tap in where that pressure sensor is. While sitting on the tractor, on the left side of the enighe, near the back above the starter. You will see a 1 1/8" or so hex plug screwed into the block, there will be a single spade connection comming from the center. Just a single wire connected to this. Take this out, get some brass T fittings or something to add the oil pressure line that will run to the gauge. The small pipe thread is standard us 1/8" pipe thread.

For the temp gauge I went with the standard Kubota set up because the sensor is the one for my engine. The gauge and sensor I bought from TractorSmart.com. While sitting on the tractor, on the back right side of the cylinder head, there is a plug where the sensor goes. You remove this plug and screw in the brass sensor. The plug is right next to a head bolt and injector. You should be able to tell which is which. From there you need to tap into a hot wire when the key is on, then the single wire from the sensor to the gauge. The gauge is marked + - S if I recall.

Wait, found the pics. First is the temp sender, you can see the yellow wire and red connector at the back of the head.

The oil sender, you can see the crass fitting in the far left sode if the picture. Then the plastic line wrapped around the large wiring harness....

Another shot, you can see the shinny brass fitting just abouve the starter, the round/hex thing just in front of it is the oil pressure idiot light sensor. Looking at the top of the engine you can see the yellow temp sensor wire going into the back of the head.

BTW, the red wired going to and from the alternator are the ones I used for the amp gauge.

Good Luck!
