- International 1066 Full sized JCB Loader/Backhoe and a John Deere 430 to mow with
Is this a fair diagnosis that my problem is my fuel injection pump?
Scenario: Tractor was being use... turned off. Next day and since forth, has not started. (neighbor borrowing it)
It's an International 444. Gravity feed from tank to filter, tube goes to other side of tank into the injection pump.
I might add that over the years, I've SUSPECTED that the tractor has not gone to full RPM's but since I'm not terribly familar with this tractor when it WAS running 'new' I don't know how fast it should go. Looking at the tach gives you a needle that is bouncing all over the place so the tach is essentially useless.
ok, now to the prognosis.
removed lower bleeder and every now & then a healthy spurt would come out but I could put my finger over it and kill flow. Upper bleeder... very little squirted out, more like spit.
So... I then removed the fuel inlet tube. The 1/8 inch (or what ever) fuel tube goes into a larger fitting and this larger fitting then has something like a 3/4" sized lock nut to tighten it down.
UNDER this assembly is a spring for some reason or another.
ok, here's what I did and is the thrust of my question...
I removed the fuel inlet, there was a 'puddle' of fuel in this oriface where the inlet use to be. The fuel was to the brim. I cranked the engine over and expected to see the fuel level suck right out of this little pocket (the threaded receiver hole for the larger input fitting)
the fuel did NOT go down at all. Nothing, nada zip.
That has me thinking this fuel pump is essentially dead.
reasonable??
