IH 444 diesel died suddenly

I was driving along everything seemed fine, when the engine suddenly revved up and then died. The fuel tank is full and I loosened an injector nut and cranked and did see fuel coming out about one drop per second. So I"m guessing the injector pump must be turning and has fuel. Any ideas?
 
One drop a second? If thats while cranking it isn't enough. Check and make sure you are getting fuel to the pump and that the return line is not plugged.

Hi, my first guess is fuel starvation. When a Diesel injection pump is being fuel starved, the immediate reaction is to fully open the governor, thus the revving of the engine. Are your fuel filters good? Is the fuel shut OFF/ON control working properly? Had the key fallout of rod at injection pump and fuel shut OFF go to the almost OFF position. Does your 444 have a fuel lift pump on the right side of the engine with the hand pump? If it does, open the bleed screws on the injection pump and hand
pump until the fuel comes out the lower screw, then tighten it and keep pumping until the fuel comes out the upper screw and then tighten it. If you don't get fuel out of the bleed screws then there is a problem between hand pump and injection pump.
Is the crankcase filling with Diesel fuel?
Is the engine backfiring into the air cleaner?
If yes, could be the camshaft timing gear woodruff key has sheared off.

Hope this helps

I forgot to that I'd turned the fuel off at the tank the last time I used it DOH!

What amazes me is how long it ran before it died. This thing really sips gas.

Thanks for the help,
Ron
 
Hi Ron,
The BD-154 engine was really economical and hardy engine. Originally developed by IH UK in the late 1950s and retired in the mid 1990s. The other Diesel engine that was in the same category was the 3 cyl Perkins A3-152 used by MF and other vendors.

Update: I went out and ran it again for about a half hour and the thing died again. This time I looked at the fuel valve at the tank first and sure enough, it had closed on its own! Apparently vibration was causing it to close.
This time I used a little more elbow grease when I opened it so it won't happen again. Weird huh?
