I have a MF-40 Backhoe, older model, a 153 Perkins Diesel. I was driving down the road and she just quit. I have diesel fuel, have bled the lines per the book, still no fire. I'm not getting any exhaust fumes out of the exhaust pipe when I crank it over. Like I said, there if fuel I have bled the system from fuel filter, high and low vents on the injector pump and at the injectors. What do we think is the problem? I've never had this happen before. Do you think it is the injector pump? All linkage is still hooked up and the shut off knob is where it is suppose to be. Where can a person get a injector pump? Thanks for any information, winter is here and We just got 11 inches and I was going to move some snow, now I'm dead in the water. Also, if Big Dean is on the board, can I take off the injection pump and rebuild it? Thanks Rick in Willard, Utah

There is one more possiblity, on the front of the pump next to the timing cover there is a line that runs back to the tank or to the bleed off lines on the injectors. This line bleeds excess fuel out of the pump, if pluged the pump builds up pressure internally and will shut it off as if you pulled the kill switch. There is a litte ball in the end of the fitting that goes into the pump make sure that is free then blow the lines out. Or just unhook it and see if it starts. This has happened to me when it got cold and froze some water in the line I belive it was condesed water from the top of the tank.

You can also hook the injectors back to the lines and see if the pump is producing enough pressure to open the injector, they open between 1800 and 2500 lbs. You can check the spray pattern by hold ing a cardboard in front of the injector. The diesel spray will certanially inject into your hand or arm or any part of you. Diesel injected is posinous and painful be careful. Other than that the other posts have covered it all i think.

Rick, I also have an MF 40 Industrial and have Until this weekend had the same problem from time to time, it seems the small fuel pump was leaking a little and also sucking some air, I changed the pump about $30.00 at the dealer and it seems the problem is solved. It was so bad that to get the thing started I had to use starting fluid but if you do be very carefull and use just a tiny bit. Also make sure you change the rubber seals that go over the lines where they connect at the pump both in and out. Good Luck. Tim

Rick,
I believe that the most probable cause is the fuel/injection system. If you have bled the system, the pump must be getting fuel. I would remove the fuel inlet line and make sure that the fuel is moving freely as this is the easiest to do. Next, I would remove all three injector lines at the injectors and turn the engine over. If you are getting a good squirt of fuel then most likely the pump is not your problem. Since the engine seemed to run fine and then just quit, you can rule out the injectors and also the pump condition in terms of wear. It is possible that if the pump is not putting out anything through the lines that something inside the pump broke. I have heard of the drive gear on the front of the pump coming loose at the three attachment bolts. You can remove the small (3/4" x 2") plate from the side of the pump to see if the pump is turning with the engine. It is not really possible for the pump to get out of time without a total internal breakage. Injection pumps are precision peices of equipment. Even very experienced mechanics should not mess with the pump head and other pump internals. Exterior gaskets and seals are what I limit myself to. If you narrow it down to the pump, look in the yellow pages for diesel injection service facilities. There should be such a facility in Ogden and several in Salt Lake City. Good Luck, Bob

do you have compression ? your cam may have broke check to see if the rockers are moveing just because you have fuel to the injectors the pressure might be to low to open the injector any good diesel shop can test your pump and injectors and rebuild them
