1973 international 3444 diesel backhoe just stopped

3444backhoe

New User
Hi my name is Matt. I just bought a 1973 3444 international backhoe. It was running good than all of the sudden it stopped running. It will crank over but won't fire. In the past when I cranked it over white smoke would come out the stack but now no smoke comes out. I don't have much experience with tractors or Diesel engines other than my ford 7.3 truck engine that never gives me issues. Please help
 
Hi Matt, first check the fuel shut off rod is
working properly and is connected to the lever on
top of the fuel injection pump. Next check the
fuel flow out of the fuel tank. One of the fuel
filters may have a glass bowl on the bottom with a
drain screw, this is to drain off any water that
may have collected in the fuel. There is a hand
pump on right side of engine just above oil
filter, this can be used to prime and bleed the
fuel system. There are two bleed screws on the
injection pump, bleed the lower one first then the
upper one. Open bleed screw and pump the hand pump
until fuel comes out the bleed screw without air
bubbles, close bleed screw and repeat for next
bleed screw.

DO NOT USE ether with the glow plugs.

I'll give that a try. I was thinking fuel filter since I drained the glass bowl and a bunch of black stuff came out. I'm having a hard time finding a fuel filter for this thing. Do you know of a good place to get one? Thanks for your help I'll let you know if it works.

I assuming the 2 bleed screws you are talking about are the 2 on the injection pump starring me in the face? The lower one has a 5/16 bolt that screws into a 7/16 bolt ( head size that is) and the upper one is just a 7/16? I've tried bleeding the fuel line. I can feel pressure build up on the pump but I am not getting any fuel out of what I am assuming is the bleeders

Hi Matt, see attached photo of CAV pump. Red arrows are pointing at bleed screws.

Well mines not nearly that clean but those are the ones I was bleeding. I bleed them some more and started seeing lots off bubbles in the glass bowl next to the pump does that mean I should keep bleeding or were you talking about bubbles in the fuel where the bleed screws are? Just asking because I can't pump and watch the fuel coming out the bleed screws at the same time. Thanks for all your time and help
 
By the way where you from? The reason I ask is I have a cousin named Jim Berhends who's a big farmer in southern MN
 
Is there a bleed screw on top of the filter
assembly? If so open it and pump until the fuel
flows out without bubbles, close and move onto
bleeders on injection pump, lower one first.
I am a little concerned that you are seeing air
bubbles in the glass bowl in bottom of filter.
Is there plenty of fuel in the tank? No visible
fuel line leeks between tank and hand pump?
Pull out crankcase dip stick and smell for Diesel
fuel and make sure crankcase oil lever is not over
full. Sometimes the diaphragm in the hand pump
develops a hole and pumps Diesel into crankcase
and air into fuel system.

I'll give that a shot tomorrow. I think we have a storm blowing in and I got to get everything picked up. By the way how do you get the hood off of these things for easier access? The hood release is not connected and I can't see where it's bolted down to.
 
Hi Matt, I am from Ottawa, Canada. You in Kansas?

Did you run it low on fuel?

I have a 424 with the same engine and fuel system. I've (stupidly) run it out of fuel a couple of times over the years.

NO warning, no sputter, no miss... just DIES.

Requires a ridiculous amount of bleeding at the two points shown, and likely will have to loosen one or two injector lines and bleed before it will actually fire.

The fuel gauge shows 1/2 a tank and I put 5 gallons of fuel in it and only have used it for maybe an hour and a half since adding it. I looked in the fuel tank and it appears there is enough fuel in it. But I can surely add more fuel.
 
Just because a gauge says 1/2 doesn't mean the tank is actually 1/2 full. Don't trust the gauge until you've "sticked" the tank a few times at different intervals to determine that it is accurate.

You can suck these tanks practically bone dry on the level.

5 gallons should be more than enough to cover the fuel pickup in the tank, even if it was bone dry, unless you are parked on a steep hill.

Ok I finally had some time to work on the backhoe this evening. I added 5 gallons of diesel. There was about 3 inches of diesel in the tank before I added the 5 gallons.
I installed a new fuel filter. I could not see a way to bleed air from the fuel filter partly because I have still not figured how to get the hood off. I bleed the injector pump (while doing so 1 off the bleed bolt heads broke off. I was able to get it out and found a grease zirt that threaded into it.) I took 1 injector line off the injector and turned the engine over. Fuel squirted out off the injector without much pressure. Put everything back together and it doesn't seem like it's even trying to start. Oh ya I the heater plugged in and a battery charger on it the whole time. I thought tractors were suppose to be simple. What do you think I should try next? For the record I'm not 100 percent sure I got all the air bleed out yet but I was racing the sun and the sun won. I also checked the engine oil and it does not appear that these any fuel in it. Thanks for everyone's time and help so far.
 
Hi, good news that the crankcase oil doesn't smell
of Diesel. If the filter doesn't have bleed screw,
tighten the filter hold down bolt and then hold
the bottom with your hand and loosen the hold down
bolt a couple turns and pump hand pump until fuel
comes bubble free then tighten hold down bolt then
move on to injection pump.
Are your glow plugs working?
Loosen a couple injector lines at the rear of the
pump just a couple turns on the nut and then
wiggle the inject line to break the seal. With
throttle almost wide open, attempt to start
engine, there will be a small squirt of Diesel
come out every time it fires on that cylinder. Be
careful when working on the injection lines as the
Diesel is under 2100 psi and can cause serious
damage to your skin.
Don't crank the starter for more than a minute at
a time and then let it cool off or you will over
heat the starter.

Good luck
JimB

I finally got it running. I bleed both screws on the pump and all 4 injector lines. What a pain in the butt. Thanks for all your help. I had no idea how I was going to get this thing running again.
 
Good news, congratulations!

I know I said you can run these practically bone dry, and you had 3" of fuel in the tank before you added the 5 gallons, but all the signs say that you ran it out of fuel.

Diesels are painful to get running if you run them out of fuel or change the fuel filters. Some worse than others. Your experience was pretty typical, and now you can call yourself a diesel mechanic!

Even after you bleed and you think you have fuel, sometimes you need to bleed again, and even a third time.

The moral of the story is: Don't trust the fuel gauge and don't let the machine run low on fuel again!
 
Hi Matt,
Very good news. We had three tractors B-414, 434
and 384 with BD-154 engine and the B-414 and 384
you could change fuel filter and just pump it full
of Diesel with hand pump and they would start
right up. The 434 was always a dog and had to
bleed the pump and sometimes loosen injection
lines.
They are one tough engine, we put over 15K hours
on B-414 and still running strong when we traded
it for 454.
