BX 23
All - new member, first tractor. BX 23 bought this spring with 1200 hours. Was told by the previous owner he had "just changed the oil", which I mistook for meaning he had just serviced it. My bad. I've used it two only three days so far - something breaks every time I use it it seems. After only using it once I blew a line on the backhoe. When I installed the new hose, I flushed it, and discovered the hydraulic oil looked like chocolate milk. So, I learned how to change hydraulic oil filter and clean the strainer in a hurry. The strainer was full of metal fur. Hopefully it's not signs of worse to come. Got it back together after a few days, next time I used it, found oil leaking from front wheel, and suspected a seal had gone. But, after much research, discovered the front left wheel gear case was cracked. I looked at the front right - it wasn't leaking, but had a hideous surface weld repair that had been done to it, and the gear oil drain plug was now welded in (I wondered why I couldn't remove the drain plug for a long time until I saw the weld job on the gear case). I replaced both front wheel gear cases (and the seals, and the bearings... over $1,200 at the dealer). I used it successfully for a day, the next day, another hose on the backhoe had a pinhole after digging only a very small hole in soft dirt - maybe a minute digging, if that. Replaced that hose, and two others that looked iffy why I was in there. Got it back together, and tested it all to check for leaks, then washed the mud off the tires. Then I couldn't start it. Read some more, discovered there's TWO controls that need to be in neutral, the hi/low range selector AND the forward / reverse pedal. Got it started, drove it around to the garage, turned the key off and removed it... but it keeps running. You name it, I did it. I tried the seat interlock. I pulled the fuse. I pulled all the fuses. I disconnected the battery. I removed the fuel line from the fuel pump under the tractor. I reread the owner's manual (it says "to shut off the engine, turn the key to off", or something like that. Hmmm. Maybe I should try that? Ya think? (did I seriously pay cash for this manual? Answer - yes I did. I'm a dope.)). I siphoned the fuel out of the tank, I used vise grips to pinch off the fuel lines. It took me two hours to kill it. I know now there's a solenoid that dumps the fuel rail, but it's pretty well hidden. Now that I know where it's at (by feel), I might be able to trip it manually (I hope), if it happens again.
SO... here's the current dilemma. I was under the tractor reconnecting the fuel pump, and it just doesn't look right. There's a bracket on it, but it's not attached to anything. The pump is supported by the fuel lines, which are stretched taunt. The wires running to the fuel pump are also stretched tight. I check through the manual, and it shows two filters, one of which is near the fuel pump. Obviously, somewhere along the line, somebody decided they needed this fuel filter more than this tractor did... OK - I now have new filters on order -the question is - which way does it go? My intuition says the filter is between the tank and the pump, and the fuel flows from the tank, through the filter, then the pump, and then to the engine. But if that's the case, why did the tractor run for at least an hour (that's like 60 minutes if your using the metric system) with this fuel line disconnected? Is this possibly a fuel return line? If not, and the other fuel line is the return, is there someway the fuel return line was able to pull fuel from the tank back up to the injectors?

Any and all help, advice, suggestions, humor, etc would be appreciated.

Oh yeah - I think (hope?) I figured out why it wouldn't stop. The bolt on the battery cable clamp had rotted completely through. That and the fuses looked like they weren't making good contact. I cleaned the fuse blades and the fuse clips, cycled the ignition, and verified I have 12 volts across that fuse for about ten seconds after I cycle the ignition switch. With the fuse re-installed, I can hear the solenoid being pulled in when I cycle the ignition switch and then released after about ten seconds. So, I'm hoping it was just poor electrical contact.

Compression ignition engine needs air and fuel to run. Next time, if ever, try starving it of air. Something solid you can put across the air filter intake, depending on hole size, softball, paint can lid, what-have-you...
Get a service/shop manual and go through it cover to cover. Sounds like someone might have replaced original fuel pump with a generic and possibly removed a fuel filter and housing? Wiring sounds funky too. Removing battery- NO! Can damage charging system, and has no effect on stopping, only starting engine.
Quit breaking stuff and just use it like you stole it- just like the prior owner!?:laughing::eek:
I would change the filter again soon to get all the brown milk out! Don't you know tractors don't run on milk!!:eek::confused2:
And you want to be sure you don't have any water in the oil- often causes milk like mixture. What does the coolant look like? That's the stuff in the radiator.....
I'm often in Waterford visiting family/friends....

All I can say is wow! The guy that sold you this tractor should be ashamed. These tractors are pretty tough little machines when treated with reasonable care and given occasional maintenance but clearly your machine was not afforded any of this.

It's not unusual for a hydraulic hose to fail after 1200 hours of hard use and its common for others to go afterwards. You were smart to change them all and you might consider doing the loader ones too.

The fuel system has a line from the bottom of the tank to an inline filter, then to the pump, then a second inline filter, the to the injector pump. The injector pump has a return line that runs back to the top of the tank that they call a return line. At least that's how it's supposed to be. Diesels shut off by stopping the fuel flow since they don't rely on spark to run so I don't think you caused any damage from fuel starvation. I think your repairs to the electrical system will fix that problem anyway.

I can't remember if someone else suggested this already but I would consider flushing the radiator and cooling system as well since it seems unlikely that this has ever been done. And make sure the radiator fins are clean. They tend to clog with dust and debris over time.

Good luck and welcome to the forum.

I have to say the same. No matter what the hours, its always buyer beware in my book. If things are not maintained, more time than not its very evident before they place their money on the table.
Sorry about all the trouble you have, my BXTLB 23 runs like a champ and does the work of tractors much larger made by other well known manufacturers. I don't think I could be happier.

Wow -- that is alot of issues for a tough and reliable tractor. apparantly the previous owner didnt care for it and you just happened to get it at that stage. as for the shutoff, you should be able to shut it off one of 2 ways, remove fuel like you tried or push the solenoid at top of engine pushing plunger in till it stops that cuts fuel. remove air by choking it at intake air filter .

Everything,
I would advise you to go to the dealer in Franklin and trade this BX23 for a BX25. Life is too short to be aggravated.

EB - Welcome to TBN. Just want to say thanks for a very humorous first post - always wondered how metric time was kept. :laughing: Glad you kept your sense of humor given all the problems you've had with your new-to-you BX23. Sounds like you'll have it all straightened out in short order.

All - thanks for the advice. Yeah, I thought about the air inlet, but in all the excitement, I couldn't figure out where the air filter was pulling air from. I was so focused on cutting off the fuel supply I didn't think hard enough to chase the air path out at the time. In this tractor it pulls air via a duct that's behind the battery access cover. I hadn't had the battery cover off before, so didn't know it was there at the time. For sure, next time, I'll be ready.
Anyway, just got new filters. So... anyone know which way the fuel filter gets installed? Photos? Anything?
Thanks!

I'll see if I can snap a picture from my operators manual, and or Climb underneith and get you one.
If you still need.
Hang in, IT'll be worth it...
