I have a 1755 that I am having a power issue with.
As some background, we had the umbrella seal fail,
causing fuel to leak into the crankcase. We
pulled the pump off and had it rebuilt while it
was off as it had been a very long time. Upon
reinstall, rolled the seal, pulled again, put back
on, no power, found a restriction in an internal port. Tore pump back apart and retuned and reinstalled again and no leaks. But ever since reinstalling the pump the last time, we have had
intermittent power issues. The tractor will wind
up as it should, but occasionally it has no power,
no smoke, and loses rpms when under very light
load, same thing as before only not as often or as bad. If you drop the
throttle down and go right back up with it, it
usually will come right back out of it. It might
run for a half-hour without issue, then just show
up again. Over the weekend, I drove it an hour
and a half round trip to pick up an implement and
it did it at least 3 times.
Like I said, we pulled the pump because the seal
was leaking. I've changed the fuel filter,
checked the fuel line feeding to the pump with
great flow. Return can be easily blown through
with little effort.
We had the pump rebuilt both times by a guy with
30+ years experience. But, I'm almost to the
point to taking it off again and dropping another
$700+ into it to take it to a different very reputable
diesel shop.
Anyone have any ideas on what might be going on
here? I have no problems with other tractors
using the same fuel source either.
Thanks in advance.
