Kubota Temperature Readings

[RICK R]

My L2650 gauge goes up half way to a mark on the face of it.

Harv,
Spent about 3 hours digging out from about 30 inches of snow with my 6 month old B2910. I use a 48 inch snowblower, that I had from an older Kubota. Temp never rose above the bottom line. I was actually wondering about it. Do you think the thermostat is locked open. Mowing for hours in the fall made it barely creep above the bottom line. I does seem to run very well, however.

Don -

From the reponses I got on this thread, my conclusion was that there are different temperature guages for different Kubota models, and that many of them behave in the manner you describe.

I don't exactly understand the value of a guage that stays at the bottom of the scale when the tractor is fully warmed up, but a lot of people reported that behavior. I guess if you ever get an actual reading of any kind, you know you're in trouble. /w3tcompact/icons/crazy.gif

hello Harv, On my new L3000 ,that is the first thing I was watching,I had seen it on a post before I bought the tractor. I have a father that has been a mechanic for 50 yrs,one of the "golden rules" of machines has been to monitor them constantly. The factory gages are probably like car ones-low quality, I plan to put good gages on promptly. My gage has barely ever passed the cold line.

Sounds like a great idea, Eric. /w3tcompact/icons/smile.gif

I'll bet a lot of people will be interested in how that goes.

Keep us posted.

Putty340,
My gauge has simple color bands and does move, but not a lot. How would you know what would be the right kind of gauge to replace with? Aren't the volt/ohm/amp characteristics really critical?

This discussion kind of makes me appreciate the true simplicity of the B7100 and the thermo-syphon cooling system. Guages?................B7100s don't have no stinking guages. They have a whistle!!! When the engine gets too hot, the whistle sounds. It's so simple. Takes all the worry about temperatures and guage needle position out of one's thought process. Of course, it's scary as all get out the first time that whistle lets loose.

My B6100 doesn't even have a whistle. As I recall, the Owner's manual kind of reads like a fortune cookie:

"When steam come from radiator, shut down engine - grasshopper"

Mine has a temp. sending unit installed into the head but no gauge, just the whistle. I have been thinking of adding a gauge, but have not got around to it. How about the old car gauges that have a fluid bulb that would screw into the head and the line that want to the gauge. as the fluid heats up the gauge would move. I guess it is like a big thermometer, needs no electric power to work. this would do the job. Have to see if I have any left from the 3 Austin Healeys that I cut up for parts. I think MGs were that same thing.

Harv,

Your statement is right on the money. My B2400 gage doesn't move much either. But one summer, it moved into the middle of its range over a 2 hour period of heavy mowing in 90 F heat. At that point I removed all the screens around the radiator and flushed the radiator luvers. Once the air flow through the radiator had been restored, the gage stayed parked at the bottom of its range.

I now use the gage as a backup means of determining when the radiator and its associated screens need cleaning. Everything gets cleaned every 10 hours (as viewed on the meter) as a rule of thumb.

On another point with regard to maintenance intervals, who follows the reading on the hour meter? Most of my work is performed at 1850 RPM. On the B2400, this means that the hour meter is running slower (it's set up to accurately measure hours at PTO speed which is around 2650 RPM). I tend to do maintenance at what I call "driver hours"-hours spent in the driver's seat.
