So you have a M39-series 5-ton cargo there, with the LDS465-1 Multifuel engine?

(If so, this thread will be moved over to the 5-ton Forum.)

It’s either the button under the hydraulic head came off or it’s the bow tie shaped washer on the quill on the hydraulic head. The washer gets wallowed out and doesn’t spin correctly. There is a video online that shows how to take everything apart.

On a side note...since you are going to have the injector lines off anyway. Make sure and spray them out real good also.

I second what Elk said...time to pull the HH off and see what you find. Also time to change the three Orings and never touch the thing again (hopefully).

I currently own a M54A2, love that beast, runs great, but a decade or more ago I had a M52A2 Tractor, basically the same truck. I ran it out of fuel accidently, I had fuel to the injector pump, but it wouldn't start, so I talked to a fellow SS member and friend and he said to have soldier B crank the truck with the throttle pedal to the floor, and then loosen the fuel line at the injector until it was squirting, to get the air out of the line then stop turning over the engine, and reconnect the line, then go to the next injector , and do it all again, until you had bleed all the lines of air, and then it should start up. Worked for me!
