L3400 temperature gauge

[Chilly807]

Those of you that have a 3400, where does your engine temperature gauge normally read after the engine is warmed up? Mine has a small tick mark just above the cold end of the scale, and the needle climbs to barely past that mark. Is this normal?

Thanks

Yup, that's what mine does, until the screen in front of the radiator starts clogging up.

Mine too. And how about the fuel guage? 9 gallon tank, and when the guage reads almost "e" , I can usually fill the tank with a 5 gallon can. Talk about a "reserve"!

My L2800 temp gauge reads the same. Just above that dot when warm. The fuel gauge is also as Adiredneck reports. David.............

Nice to know mine isn't the only one, I was starting to wonder if I had a stuck thermostat. I'm used to seeing temperature gauges read mid-scale under normal conditions.

That's my kind of fuel tank !! I occasionally try to squeeze a few more hours running out of a tank that thinks it's getting low. Sometimes it works, sometimes you end up walking out to get fuel...

Ditto with L2800... and been there with the radiator screen clogging up, the needle will peg and steam will blow...

Not sure why they even have a 9 gallon tank if you have to guess after 5 gallons.

I've bled more than a few fuel systems after they've been run dry, a pessimistic fuel gauge is a godsend. The sooner we think it's empty, the sooner we refill it, and we're pleasantly surprised at the "great fuel economy" we're getting too !

Same temp reading on my L3400. I usually fill the fuel tank at about 1/4.

How many gallons do you fill when it reads 1/4???

 

[beersngars]

Sounds exactly like mine on the temp gauge. When the fuel reads at 1/2, it takes a tad less than 5 gallons.

My L4400 does the same with the temperature gauge. Ran a baler last week for a few hours and never got over the tick mark.

My fuel gauge is just opposite. It can read just down to the F on the full and I can put 5 gallons in an 11 gallon tank. I have never ran it down to E for that exact reason.

 

[Chilly807]

So this is telling me that the temp gauges are pretty much all the same, and I'd better use my own judgement with the fuel gauge.

Strange that Kubota wouldn't have used a temp gauge that read mid-scale when warmed up, so you could tell when it was close to normal operating temperature warming up.

Maybe that little tick mark was meant to be a milestone kind of thing, as in "don't work the tractor hard until you reach this point". The manual doesn't mention anything about it either, or even where the gauge should normally read.

The fuel gauge doesn't surprise me, the tank is an odd shape so it's pretty hard to have any kind of a linear level reading on that.

I don't remember exactly teg. I think it is around 5.5 gallons.

I do not have an L3400, but this may apply none the less.

My BX24's temperature gauge was working properly at first. However, over a periord of about 1 year, the operating temperature slowly decreased until the temperature gauge never moved. I thought that I needed to replace the thermostat.

I found that the temperature sensor has a spade type connector that had become loose. It was not the wire connnection, but the crimp of the spade piece that is part of the sending unit. Over time the engine vibration slowly worked the crimp loose. The unit is right on top of the BX24 engine and I staked it down with a small punch and a hammer. The stud and spade piece is mounted in a plastic insulator, so you can't stake it too hard. The gauge now returns to mid travel when the engine is up to operating temperature.

Used my L3400 this weekend for an extended period of time cutting fields. I could feel the heat coming from the engine on my legs and the temperature guage stayed just passed the tick mark.
