Kubota BX2200 with LA112 Front Loader

varmint · Feb 15, 2016

There's currently a thread here on TbN about replacing torn boots on a Kubota, and Messicks is a good place to start in finding just the boots. The tread has some good photos of how to go about it- looks very easy.

If you email Kubota with your model and S/N, they will let you know the date of manuf. for your tractor. I've done it three times for used Kubotas. Wish I could remember just how, but if I can do it, it must be easy.

I changed the engine oil and filter today. Old oil was pretty dark. Coolant looked pretty good so I think I will hold off on changing that. Next up will be deck service (blades, gear oil change, grease fittings). I have the 60" MMM. That thing is heavy! I did notice the other day that my fuel gauge wasn't working. After a restart, it was functional again. I removed and cleaned all of the fuses. Sticky fuel level sending unit perhaps? Anyone else had this problem?

Oh, yeah. Definitely have had problems with the fuel sending unit.

It turns out that the fuel sending unit's seal will leak. It is under the left side fender. Be on the look out for fuel in the area when the tank is full.

Anyway, there was a TSB on the problem and my dealer replaced the seal. Then the fuel gauge didn't work correctly. I took the BX back and the dealer, a mom and pop business, and the owner told me that the fuel float is a convoluted mess and has to be installed PRECISELY or it will hang up on the wall of the tank and give incorrect readings.

So they had to take off the ROPS and all the flashing again and give the float a twist to get it to read right. Well, the new seal also leaked so back the BX went. And the fuel gauge didn't work right again. So back it went again! It must have cost a fortune in labor to replace a $2 seal.

But now all is well.

As far as reading correctly for a while and then not, that is exactly the behavior my gauge had when it was necessary to adjust the float. Your BX may have had the seal replaced and not had the float lined up just right. What you do about it, if anything, depends on how accurate you want the readings to be. Mine seemed to be OK with a quarter tank or less remaining. But that means you'd have to keep a close eye on it to avoid running dry.

And diesel engine oil will get dark and ugly with just a few hours on it. Not to worry.

Thanks gwdixon! I am pretty good with a wrench, so I may take a look at it if it acts up again.

So yesterday I started up my tractor and it stumbled for a couple minutes. When it was stumbling, I could not effectively increase or decrease rpm. After a couple of minutes, the tractor smoothed right out and I used it to grate the road for 30 mins or so. Any guesses as to what it going on? Air in fuel system? Like I said in previous posts, I replaced both fuel filters and have had the tractor running with no issues, so I think any air in the lines would have disappeared by now.

I would start with some fuel system cleaner. Also, maybe some water in the system.

No big deal, mine's done the same, as mentioned try some conditioner, maybe a little Heet for diesel (different than for gas). If it continues, go from there, blowing back into the tank to clear intake, etc., there are several old threads on this if it continues. Keep us posted.

I fuel mine out of a bulk tank with a filter, some use a funnel with some type of filtering element.

I have a BX2200 I bought in 2001 with 950 hours on it. I have had to replace the seals on the swivel joint on both sides of the front axle. I have the leak in the fuel tank and just don't fill it up. Love the tractor! Made a cab for it. Added a loader quick attach from my tractor tools Tach-N-Go + INNOVATIVE ATTACHMENTS and forks, really handy. I also upgraded the generator from a 7 amp to a 45 amp with a kit from Kubota.

Over the weekend, I cleaned and serviced the mower deck. I need to replace one of the wheels/bolts (front right wheel has a lot of slop). I haven't run the tractor again yet, so I am not sure if my previous shudder problem is gone.

warment · Mar 4, 2016

So I fixed my gauge problems today...very easy...just jiggled the fuse holder and they functioned normally. All I did was remove, clean and reinstall the 15 amp acc fuse.

Also...I forgot to mention that I ran the tractor over the weekend...no sputtering during startup...no sputtering after running...My problem must have simply been air in the system due to fuel filter change...

Good news. Might add some di-lectric grease to the fuses to prevent the problem in the future.

warment · Mar 7, 2016

Thanks for the tip...already did it! Believe it or not, I cleaned the fuses (elec spray) and used grease prior to this problem. I guess the fuses just needed a good sanding/scuffing as well as grease...I might go ahead and replace all of the fuses with new ones in the near future.

Does anyone have recommendations for new fuel line? I think I have a slow drip between the fuel pump and the filtet next to the motor. I might just go ahead and replace all fuel lines. I assume they are original.

warment · Mar 27, 2016

I replaced the 2 fuel lines between the pump and the engine yesterday. This fixed my diesel drip. I could not find any holes in the old lines though. I assume the lines were original and were leaking near the engine fuel filter.

I have been getting the Gates Barricade fuel hose.

Barricade(R) Fuel Injection Hose (MPI) | Gates Corporation

Not cheap but it is supposed to be good.

Thanks for the tip. I already bought several other lines that I will replace later. I have the one that goes between the first fuel filter and the fuel pump and also several return line pieces. The 2 I replaced fixed my problem, so I am happy right now.

warment · Apr 14, 2016

If anyone is interested...the fuel supply lines are 5/16"...I finished replacing the last 2 small sections between the tank and fuel pump yesterday. I am going to start replacing the return lines within the next week or so.

warment · Apr 18, 2016

Does anyone know the size of the return lines? They are smaller than the 5/16" supply lines. I am guessing that they are 1/4"? I will try to measure within the next few days.
