Hello, just a little background, I'm new to tractors
this is my first one. I'm very technicaly inclinded just
not a whole lot of diesel experience.
I bought this mid 80's Universal 640 DTC from a
guy that barely used it. It was hard starting unless
plugged in which I think was commen for almost 35
F. But has always started and white smoke until
warm. Last Sunday my wife was on it for a couple of
hours moving gravel in the driveway and ran great. I
got on it a few days later to warm it up and change
the hydraulic oil. It started up and ran for a few min
then stalled now won't restart. It still had the fuel in it
from when I bought it and was far from empty but I
added some. I have new fuel filters so I decided to
change them, the primary was full of crap. Bled the
fuel system. The manual pickup pump quit
sometime ago so the previous own installed an
electric unit. Bled through the filters and the
injection pump to the injectors. When cracking open
the injector lines there doesn't seem to be much
pressure it just trickles out, from what I know about
diesels it should be very high pressure?
So my question is did something happen inside the
injection pump causing no pressure? Or is there
something else I should look for. Would you
recommend taking the pump apart myself or just
send it out for rebuild? Any insite would be great.
