Help - Snapped Head Off BX Fuel Bleed Screw

[bluedunn]

Hi-

As the subject indicates, I accidentally over-torqued the fuel bleed screw on my BX1860. I haven’t looked to see how difficult it is to replace this (or expensive), but it looks fairly straightforward. I pinched off the fuel line that comes from the filter into the assembly, which this screw is part of, but I do still have a tiny bit of fuel leaking - currently being caught in a Tupperware container.

Anything I can do to stop the leak? I’m assuming this is fuel that is already in the engine and not coming from the tank, since I pinched that line off. Any advice when I do this repair (besides don’t yank on the screw so hard)?

Thanks!

Is there any screw to grab on to or did it break flush with the casting? If it broke flush, I would level the top with a dremel tool and centre punch the screw before attempting to drill it out with a left-hand cobalt drill bit. It might catch and wind the screw out for you. If not, it leaves a nice hole for a screw extractor.

As for the fuel leak, I doubt much will backfeed from the engine, any quantity of fuel is probably coming from the tank. Make sure you have two flat surfaces to pinch the line off, not just a set of vise-grips -- two pieces of wood or metal to sandwich the line.

Broke clean off at the casting. Think I’m going to order new parts -they aren’t expensive and probably/hopefully less headache than trying to extract the screw.

The dripping diesel doesn’t seem to be coming from the inlet, where the screw is broken off. Actually seems to be dripping from above the oil pan. This makes me think it may be residual diesel that shot out into the engine when I was initially bleeding the system. I don’t know where else it would be coming from.

Just a side question. Wondering why you were bleeding the fuel system. I ran my BX2200 out of fuel a couple times, as did a friend with a BX22, and neither of us had to do more than add fuel and start the tractors...

Fair question. I replaced the fuel pump, under the tractor. Figured I needed to get any air out of the system...

Ok, I think I've ruled residual diesel in the engine compartment. Got up this morning and there was about 1 cup of diesel in the pan I set out last night (around 9pm).

That said, I think (hope!) that I've narrowed the leaking diesel down to the component that is adjacent to the injection pump...the part the fuel line from the fuel filter goes into. I think there is supposed to be a copper washer between the injection pump and this part - there was not. How it has never leaked prior to this, I don't know, but I think there was some residual diesel in the injection pump that was backing out of the hole and past this component, which was easier because there is no copper washer. I snugged up the banjo bolt pretty well (screw still stuck inside) and that seems to have slowed things down. Parts on order...

Parts should be here on Weds. Is there anything I should do after I put on the new banjo bolt and bleed screw? Just run the fuel pump?

Thanks for the help!

First I don't know if you will need to do anything or not. Hopefully someone with experience will chime in.

As I mentioned, I do know that twice (in 16 years) I ran my bx out of fuel and each time just added fuel and it started right up. Do not remember if I let the fuel pump run a bit before I tried.

I got the impression that the bx fuel system is self bleeding. But don't know for sure.

What I would do is replace those parts, turn the key on, let the pump run a bit, and then try to start it.

It will either run or you can then an ask for more help.

Thanks. I mean, I think that's what I'll end up doing, but wondering if there were any 'gotcha's' that I should watch out for. The work itself seems very straightforward.
