BX24 problem

[Johndeere3720]

I was taking care of my neighbors horses last weekend and his BX24 is not running good. When you give it throttle (typically about 2500 rpm) it runs strong then almost dies goes to half throttle, back up and down and so fourth. I have heard that when the throttle control gets loose on the in the injection pump it will do this but have also heard of something similar with the fuel filter. I told my neighbor about it yesterday and he really wants to get it fixed since it is a "style cramp-er" when your tractor bogs down at any time and "wimpy" having a tractor that cant run right. Help would be appreciated, he wants me to do the repair, luckily I have experience with both the fuel filter (BX24 has 2 of them) and have taken the injection pump on and off my Simplicity 9518 diesel tractor multiple times due to poor parts quality. The BX24 has relitively low hours on it, my guess is between 200-400. Thanks guys!

I have yet to replace my filter and its over 500 hours. If the engine surges, perhaps it does need filter replacement. Its pretty simple, just replace both, underneath tractor and in engine compartment.check the air filter as well.

I did pull the air filter and it is almost brand new. makes me wonder when it was last serviced.

Fuel filter would be the best place to start. Diesels like nothing more than clean filters.

For doing this will I have to remove the FEL and grill guard to get the side panels off? And if I remove the FEL (likely) will I have to remove the backhoe to keep the front tires on the ground or will it handle it fine?

I don't have any experence with the piticular tractor you are having problems with. I'm going off of experencies I have had with diesel engines. It seems odd that you would have to remove the FEL to gain access to the fuel filter. If you do, it seems like poor engineering on the manufactures end. The tractor should keep the tires on the ground with the FEL removed. Be careful moving the machine with it off though. The front end will be much likely to come "unglued". Espically when "jerking" forward really quickly.

Thanks, worst case I have 200 pounds of tractor weights I could hang on the front bumper to help even it out. And with the side panels, I think they are integrated into the grill which cannot be removed without removing the grill guard and the FEL. With this, I want to be as safe as possible so removing the hoe may be in the equation as well although i don't necessary want to do it if possible not to.

I don't have experience with that tractor, but, with my Massey.....I just raise the bucket up in the garage, and throw a chain around the bucket and the rafters to make sure it doesn't fall on me. They only weigh a couple hundred pounds on these small tractors, doesn't take much to make them safe without total disassembly.

You shouldn't have to remove the hoe.
Actually just the grill guard and side panel's If you don't mind working through the arms on the loader.

While you got the lower filter off drain some fuel in to a clean bucket maybe the blockage in in the tank you are all ready 3/4 there to check it with the filter off.

There was a guy on here that purchased a 'rental unit'............turns out that someone put epoxy or something in the tank, and it kept blocking the fuel flow.

Would be a good idea to check the tank also. Not to mention the time I ended up with bugs in my fuel filter on my old Cub Cadet..........LMAO

Don't bother with the FEL in the air. Either take it off (it only takes 5 mins) or lift it up and lock with lever to prevent accidental bump of joystick.

There was a TBN'er who had a fuel line pinched slightly from a zip tie.
Change the filters first and check the line. Be sure the fuel comes out freely from the bottom when replacing the filter.

I am pretty sure it's something simple. Those BX24's runs like a beast like mine.

 

[radioman]

I just realized something- maybe its the seat.
There was a older style seat that would make a lightweight user slide forward enough and let saftey switch kick in. Some of the BX24's have them. I have the newer style.

Since the tractor is pretty new, the owner probably has the operator's manual. I suggest you borrow that manual and see what the filter replacement entails. Seems like most responses here have been educated guesses.
As far as removing the FEL for access....maybe a jack stand or two, or make sure the backhoe bucket and stabilizors are down.

BTW, while you're replacing the fuel filter, check the water separator (if it has one) too.

roy - I have a bx24- no need for jack stands. takes 5 mins to remove. for the first filter just go underneath the tractor and will be right there. nothing to remove, nothing to take off. The owner manual may still be on the tractor. flip up the seat and look on the gas tank. its in the black bag. I wouldnt bother with the manual- not needed.
Now I just remembered that messicks has a nice clear instructions for filter.
take a look here

Radioman i am not one of the safety police but i implore you not to do this, somebody accidently moving the joystick is the least of your worries ( i think you are going to know if there is someone in the vicinity when you are working under the loader), it is more about the sudden and catastrophic failure of any part of the hyd system that can catch you unawares. If you must work under the loader then make sure it is propped by a secure means ( i normally use a piece of 40x40x5 mm angle iron from the top of the lift cyl to the frame ). My mate thought he could move quicker than the loader can fall if it was to happen he was just lucky he was skinny enough to fit between frame and engine however it is still gonna take time for the broken shoulder,arm and ribs to heal not to mention the 40 + stitches he has in his back where he had some lovely gouge marks. If it had been me then i would prob not be here today

Thanks for all the help guys! :thumbsup: I will more than likely remove the FEL for better access to the engine. For the fuel filters, they are directly under the tractor? If there is a pinched line, it should be an easy fix, even an old filter, I just want to help out my neighbor. :thumbsup: With the filter, any estimate on the cost on one? I can call my local Kubota dealer too but I will have to wait until Monday. Thank you all for all the help and support! :thumbsup:

I had a problem with my BX24 last year, that sounds very, very similar to your problem. Turned out it was a linkage problem with the HST pedal. The unit was purchased new in 2008.

I took it back to the dealer since it was under warranty. The shop manager advised me a couple hours after dropping it off, that it was a linkage connector or something, that had gotten loose or fallen off, though I can't recall which.

Anyway, they fixed it and it worked without any further issues until I traded it in February this year.

Before you start going into the guts of the machine, look underneath it and check the pedal linkage.

Good luck. :thumbsup:

Thanks, i will have to check that out. Do you have an idea what they had to do to fix it? It does it moving or not, even using the hydraulics on the FEL or the Hoe.

I believe it was the linkage right under the pedal, a clip or retaining nut, or a clip with a retaining nut came loose and caused boggy performance...not always, then got progressively worse. Got to a point I'd pray and it'd go for a bit, then not move, then go again.

Apparently the linkage, as it moved, would grip, then let go, not grip, not grip and grip and act like there was nothing wrong.

FEL worked fine, no issues there, but the boggy performance you described put me right back into the seat like it was yesterday.

as for the fel in the air- thats why i suggested to take it off. It is NOT necessary to take FEL off- but for a first time working on BX its sure is nice and feels comfortable. Like I said before less then 5 mins to removed, I am not sure why we are still discussing about the FEL removal or not. It gives you the elbow room. I just about never leave fel in air when working on the engine.

Now there are 2 fuel filters. one is on right side of tractor. you can see it with hood open but you will quickly see that you might want to remove the bonnet since its plastic and it give you all the room needed to work on it. The other filter is right underneath tractor. Please review the link from messick I gave you, it explains all this. Its not all that hard.

I think you guys are over thinking it as the BX is really easy to work on for the simple parts. Its just the first time doing it feels and looks imitating. (I know the first time it felt awkward, but then same goes for first time with everything.)
