1st time changing oil in B2400...Murphy\'s Law

Last week I changed the oil for the first time in my B2400.
100 hours (the 50 had been done by the prior owner). I
thought I had the engine pretty warmed up but when I
dropped the screw only a cup or two came out. Figuring
There was plenty remaining, I ran the engine a while
and then drained more oil. Still slow, but more came out.
Mistake #1: I didn't check to see how much came out,
and ended up putting the old oil in a container that already
had used oil, so I could't go back and see how much I
needed to put back in! Talk about a newbie! Next time
I put the old oil in a container and measure how much
came out. I figured this out today (see later).

I ended up putting nearly 3 quarts of oil in. (I didn't change
the filter). Later I check the dipstick. The level was way
high, much past the hole indicator that says "full". The
distance between the low and full holes on the dipstick
is about 1 inch. The oil level was about 3 inches above
the "full" hole!

I decided to drain some oil to try and get the level in the
dipstick down to "full". I did some mowing. I noticed that
the engine temperature indicator was a lot higher than
normal. Nowhere near red, but about half way. Normally,
the indicator is less than a quarter way up. I stopped
and noticed some coolant was flowing out of the overflow
tube. Then I noticed that a lot of the screens on the
front of the tractor were clogged with grass. I cleaned
out the external screens as well as the screen in front of
the radiator.

I waited a couple hours then drove the tractor for a while.
It still seemed to be working hot but not as hot.

I then decided to empty out some more oil, as the
dipstick level was still way high. Only about a cup came out!
I figured the tractor was not warm enough so I drove it for
a short while. Dipstick level was still way high. I drain the oil and still only about two cups come out. But, the engine really is quite warm.

Now I am stuck! Dipstick says oil is off the scale. I've drained a few cups or so (maybe a quart but because I have not
been keeping track, I am really lost in terms of how much
came out...again!. Jeez).

Anyone have any ideas? Is the dipstick registering way high because there is too much oil, or could there be another
reason? Why, if the engine is warm (I would say hot)
doesn't more oil come out?

Hmm. I just thought of something. The tractor is parked
on grass near a shed. I am not absolutely certain that the
ground there is level. I think it is, but I bet that if it isn't,
that could be causing both issues. If the tractor is not on
level ground, it is only a little unlevel.

Anyone have any other thoughts? Even "You are truly an
idiot" is ok ;-)

I take it you didn't get a manual from the previous owner?

Well, I'd first contact he closest Kubota dealer and find out what the oil capacity is. If you don't have the manual, may as well order one while you're there. May as well get an oil filter too, while you're at the dealer's.

Then, I'd go home and change your oil properly.

That's what I'd do, friend...

Oh yeah, and park that machine on a level area!

You didn't mention what the oil smelled or looked like but I think what youv'e pulled the plug on is the front transmission case. Only a small amount of oil (Couple of pints or so) is in this case. The engine oil plug is on the right rear of oil pan and is in a vertical position.The trans. plug, as I recall, is in a horizontal position and is easier to see than engine oil plug. You might want to check your hydro fluid level and see if it is low. If so your draining the front transmission and not the engine. Too much oil in the motor can cause it to run warmer also. I'm not sure about how the oil gets to the front case or even it's purpose ( a drop box to lower drive line???) but it is lubricated from the main transmission reservoir.

Hi,

In addition to what B2400 man said...

I would be VERY CAREFUL using that tractor at all until I understood what I did.

You certainly don't need to damage the engine or the drivetrain by draining something you should not have and running it dry...

Not to sound cold/crude/rude...but tractor repairs can be VERY expensive...I would be very cautious if it were me...

This isn't winter in Alaska, oil should flow out of any vehicle in these temperatures even without a warm up. Something is wrong or you drained the wrong area.

I bet it does take about 3 quarts, my tractor motor is a little larger and it takes 4.3 quarts. You are so overfilled because in reality you drained none.

Assuming that you are pulling the drain plug, you might also unscrew the oil filler cap. There are times when you will get a vaccuum lock and the oil will not flow very well.
Additionally, I have a 2200 and have found that the dip stick is far from accurate. In fact, the capacities in my manual are off as well. It would seem that someone at Kubota can't figure the metric to American units very well. If you can, make sure you have the proper dip stick by measuring it and comparing to another 2400.
Good Luck!

You are in Virginia, so it is not engine temp that is causing lack of oil flow. As mentioned, oil at air temp there will flow just fine. I strongly suggest that you don't run this tractor again until you find out what is going on! Buy, beg, or borrow a manual for guidance or seek assistance from a pro. Running these tractors without fluids (or with too much) can be catastophic for them.

And this isn't the kind of place where you have to worry about being called an idiot! We have all been newbies at one time and are here to help each other out. /forums/images/graemlins/grin.gif

Re: 1st time changing oil in B2400...Murphy\'s Law

how did u make out with this problem. i think i would agree w/ b2400 that u removed the wrong drain plug and were removing tranny oil and adding motor oil. the service manual calls for 3.0 liters (3.2 qts )with a filter changefor the b2400.as a side bar the manual calls for 12.0 liters(3.17 gals)for the transmission case.hope all is well w/ the tractor

I just got in from (hopefully) making everything better.
I went to the dealer and they had an old B2400 in the
back. They showed me the oil drain plug and I said Aha!
But, the plug that I drained was not on that unit! It looked
a little different. So I went home and looked a *lot* more
carefully at things. The B2400 on their lot didn't have
bi-speed...and mine does. So, I figured that I did drain
some kind of front transmission case related to the bi-speed.

I do have a manual and as we all know the graphics are
rather lacking. Both of these drain plugs are horizontal.
The front transmission case is located almost dead center,
almost under the radiator. The oil drain plug is much farther
back, near the fuel filter, and hidden by the FEL bracket.

The manual does not mention this part of the front
transmission case and does not have a graphic that
shows this part of the system or plug! For a bi-speed, they
show a plut that is much closer to the tire, not the center of
the tractor.

I drained the old (and new!) oil and replaced it with new oil.
I added UDT to the front transmission case per the manual.
Both dipsticks register properly now.

I really, really appreciate all of the guidance I received.
It was very helpful. I didn't reply until I learned something,
which was basically today.

I took some pictures of the transmission case showing
the drain plug. If anyone has an interest, I can post the pictures.

BTW, I just finished a shed/garage for the tractor. Took
two months in my spare time, from digging holes to finishing
the ramp. Had some part time help. Picture attached!

All of you folks take care!
