Hope somebody can help me out? I have just completed atop to bottom rebuild on an Oliver 232 6cyl diesel.Every thing has been replaced.
The injector pump has been refurbished by a factory auth. service. it wants to fire but just sputters. It ran for about 5 seconds.I have bled
the fuel system many times. I have found some leaks on the return lines. Will be replacing all before next attempt.This is my first diesel and although I under stand the concept of the injector pump,I don't know if there is something I should be fiddlin on it while cranking. I have the throttle wide open per recomendation or the folks who rebuilt it. I am also going back to square one on setting the timing.When I originally set it i Watched the #1 intake drop and dialed it to the top on that revolution, and stopped at 4deg BTDC. Ihave since obtained a correct book for my machine and it says I should be at 2deg ATDC. By the way not that it makes any differance my machine is a White 2-63 Industrial TLB. Thanks for any help.

You are on the right track. No diesel will start with air in the low or high side.

What injection pump does it have?

If it ran for 5 seconds, this would likely rule out timing as the cause for it not starting. While the timing ultimately needs to be set EXACTLY to spec, it should still start even if the pump timing is 10 degrees off either way.

Check and double check that there is a good flow of fuel to the pump, and that the fuel return system is not restricted.

It needs to crank over FAST with the starter, or if you have a reliable helper you could try pull-starting it. BE CAREFULL!

check, bleed, check, bleed, check, bleed. If you forget that, check,bleed till you're blue in the face. YOU WILL OVERCOME!!!!! !!!

It wouldn't have kicked off period if your pump timing was the problem. You're not getting a constant supply of AIRLESS FUEL.

Get a battery charger, you may need it, but don't crank too much at one time as you'll be adding a new starter to your list of things you did in your restoration.

Best of luck,

Mark
