DT436 injection- tell me it ain't so!

Posted by P Backus on September 11, 2005 at 21:38:20 from (69.128.32.90):

I have a 4166 (with the DT436) that has been acting up. After
running a couple of hours, the engine will starve for fuel, dog
down and then die. Doesn"t want to restart. Sometimes you can
save it by getting the clutch in and letting it "catch it"s breath". If
you let it idle for a while to cool down, or if it quit entirely, come
back after an hour or two, it will start right up and be good to go
again for a while, "til it warms up good again.
So, I changed out both fuel filters, air filter is clean, no crud in
the tank because I replaced the bottom of the tank recently. The
engine itself is really solid- no excess blowby or oil usage. Same
problem.
The tractor, as long as I"ve owned it, never has been a great
starter, and it always seemed kind of gutless to me. The pump
still has the seals on it, so it"s not been changed. I know that
these pumps can be turned up easily, but I"ve never done that.
So, by any chance, is there anything that can be done to help
this thing out, or am I due for a rebuilt pump? Would "turning it
up" help anything at this point? Is there a way to test and repair
the "charge pump" that supplies fuel to the injection pump, or is
that integral with the injection pump? Will FEMA send donations
to "injection pump victims"?
