282 Diesel Shut Down and Will Not Start

[Lawmar]

I have a friend with a 282 diesel in a Galion grader that when I first saw it a few years ago I thought that engine looks familiar. After a couple minutes I was pretty sure I was looking at the same 282 used in the 560 and early 706. The other day it just shut down and will not start. I have not worked on these and since my Dad passed three years ago I cannot ask him where to start. It sits outside in the mountains of Colorado where it gets little rain and is semi arid environment. He had just filled it with fuel prior to grading some private roads. Because working on anything diesel is well… dirty and ruins clothes, and I am a visitor from out of town, I was hoping to find out if these have some common failure points. i was going to start with the drains on the filters to see if there is water there. I was then thinking about cracking to fitting that feeds the pump to see if fuel flows there. I am a little hesitant on that as it appears to be a swivel fitting and sometimes once moved they leak. Then I was going to crack the connection at the injectors to see if there is fuel there when turned over. There appears to be a return line on top of the pump where the fuel shut is so I am uncertain how to check the fuel shutoff. I have never been into one of these pumps. Those are my thoughts. Hopefully there are people on here that have experience that can help point me in the right direction.

First of all, is there an electrical shutdown on the injection pump (if so there will be an electrical wire going to it).

If none or it 'clicks" when power is applied other causes of a quick shutdown would include a failed governor damper ring that has clogged the fuel return with "coffee grounds-looking plastic", or a snapped pump drive shaft due to the hear and rotor seizing from water or other contaminants in the fuel.

Mechanical cable to the fuel shut off.

If the return line plugs it will stop. Loosen that turn line on top of the pump and see if it starts. Yes u can loosen the injector lines to see if fuel is pumping. On the tractors there is a check valve at the bottom of the tank where the return hooks up. There is a disc in the pump that starts to deteriorate and it plugs the return check valve. So if u loosen the line on top of pump and it starts you have found your problem. You can clean out that check valve but it will just plug up again. Meaning pump overhaul time. That’s about all that can cause these engines to stop other than running out of fuel. Plus the fuel filters would have to be totally plugged to cause a stop deal.also them fuel filters are on a slant on the tractors. So make sure the bleeders are at the top! I have have seen them in all kinds of positions just like u have here. Air has to come out at the highest point.

The check valve that rustred refers to is at the pump where the return line connects on some construction machines. If plugged machine may idle at best. Also on the side of the roosa pump is a small rectangular cover held on with two screws. With the cover off you can see if the pump is rotating. You will get some fuel leakage with the cover off . Good luck

Looking at the picture, there is no return line out the top of the pump, so no return check valve?? or am I missing something, because that would have been my first guess also

YES THERE IS a top return line in that picture. and IH D236/282 pumps never came new with a top pump restriction fitting but used a one way check valve at the bottom of the fuel tank t return line end. An easier quick check is to loosen the two screw side timing cover on the pump side, if engine then run OK WITH the fuel leak, but dies with cover tight it's confirmed injection pump needs repair.

On the side there is a small Rectangular cover that is held on by two small flat head screws. When I remove that I get a lot of diesel. It just keeps running out.

Ya, it will do that. You can shut the valve under the tank to stop it. Your mission is to see if anything turns is there when the engine is cranked. What kind of condition is the exhaust in? If pretty good a quick check would be to see if it is pumping air out the exhaust. No air likely the cam drive gears have stripped.

Ok, I should have blown the pic up more, see it now. The wires across the pump kinda hide it

yes u will get fuel leaking , did you do what diesel tech told you to do in post 8 ? you have the diagnosis info but you must follow it to confirm your problem. either do that or remove the return line one or the other.

I had a 503A Galion Grader with a UD236 engine from new, 236 is a shorter stroke version of a 282. They look about the same.

The cover is not removed for Dieseltech's check. You only need to loosen the cover a bit to let some fuel trickle out, when you try running it as Dieseltech suggested.
