Howdy! New member here. Glad to meet y'all.
I have a problem with my tractor and I am hoping that some of you fine folks could shed a little light on it.
1989 Massy-Ferguson 383 Perkins 4-cyl diesel.
The RPM's will go up and down slightly and soon after the tractor will shut off, just as if I had pulled the fuel shut-off lever. Cracking open an injector at the cylinder head and turning the engine a little while usually allows it to restart (after spewing out some fuel, and I assume air as well). This vicious cycle of cutting off and cracking open injectors goes on and on.
This is the first and only diesel I have ever had experience with, but I am assuming that there is air being sucked into the fuel delivery system somewhere, and through quite a bit of brain-cramping thought, staring at the fuel system, and bleeding this and that, I have come to the uneducated conclusion that the air must be getting into the system through the injector pump itself. *Side note: There are 2 bleed screw on the injector pump. Fuel only comes out of the lower screw, none from the upper bleed screw. Shouldn't there be fuel from both? Could this be an indicator of the problem??
Anyway...I have about resigned myself to the unattractive option of removing the injector pump and taking it to a repair shop to be rebuilt. So my question is,
Does anyone know how to remove the injector pump?
I have a fair amount of automotive experience in the past (just not with diesels) and I think I may have an idea about how this should go, but I thought I might find someone here who has done a similar task before and could shed a little light on it for me.
Thanks for reading this long post from a new member.
