bleeding an HD3 Allis diesel?

Forum Members,
Have been trying to start a '65 Allis HD3 crawler without success. About the only things left are did I bleed the lines at the right spot? Can anyone fine tune me on where lines should be bled ? Second thing is completely removing all fuel, mostly new fuel, and adding cetane to get a better ignition point for starting. Am about to give up on it if these things do not help!! Any and all thoughts are welcome.

Put air in the tank, seal with a rag, Loosen bleeds or injectors and force air out until straight fuel runs, or pull return fuel line off going back to the tank and put air to it with bleeds or injectors cracked. Not familiar with the particular system, but will work for most all.
 
If its like an hd5 it uses a Detroit. On the side of a Detroit there
is a roots blower. Usually there is an air dam that is spring
actuated to act as an emergency shutoff. A good many of these
have made people think they have fuel problem. also according
to tractor data they only made 30 hd3. Is that accurate?
 
JR,
This HD3 is a '65 version. You are correct saying they made only a few HD3's in the '40s. This is a newer one made from 1960-68. Not sure what engine is in it, four cylinders with the
Roosa-Master injector pump.

A Rosa master pump won't be on a Detroit. They're a common
rail two stroke. Putting air pressure to the tank isn't a bad theory
as was brought up before. There should be a blender on the
pump body itself. I usually end out cracking all the lines at the
injectors on a rosa master system. If you have someone to
crank it and you tighten up the nuts one at a time as fuel
bubbles out while the engine is cranking seems to work best in
my experience. Either in excessive quantities works good to but
kinda brutal. Lol
