Ford 6610 Hard Starting Issues

[mojust84]

First of all many thanks to all of you who share info to keep our tractors moving when we need them.

I am currently having an interesting issue. I have a 1985 Ford 6610 that has been in the family since new. A few months ago I let the tractor set for a week while out of town and when i came back it was near impossible to get started.

It ran fine before i left. The first day i had the problems i changed the filter cracked all the lines and bled the system. it would then fire up for about 5 seconds and then starve off.

I went to check the injection pump oil and it was bone dry! so i serviced it per the manual and now if the tractor sits for more than a day it will do the same thing with hard starting then starting up and dying off several times before it runs like a champ.

what puzzles me is after the initial morning start i can fire it up as many times and work it all day long with absolutely no issues.

i need this tractor and have come to the point where i will more than likely go have the pump rebuilt and injectors as well to see it this solves it unless i can figure it out in the morning.

any ideas, tricks, or tips anyone has would be great. the tractor has 1800 hrs and the last injection pump rebuild was at 900 i believe.

Thanks in advance!

1800 hours.. and it's ALREADY had an injection pump rebuild? that's kinda odd to me... i'd kinda expect more like 4000 hrs for that.

is it loosing pump oil fast?

after it sets are you finding air in the injector lines?

In order to start, a diesel engine in reasonable mechinical condition needs fuel, air, and a good battery/starter to crank it over.

I would suspect your fuel system is losing prime after sitting overnight. That's usually caused by an air leak in the fuel delivery system. Make sure your bleed screws are tight as well as all the fitting in the fuel delivery system. Look for small cracks in the lines or any dribbling of fuel.

Replace the transfer pump.

uhhhh feeling very mechanically declined ATM.......Transfer Pump??????

Also i found something interesting today. it really had only sat for about 15 hrs since it was ran yesterday and when i went to start it the battery was down from all the cranking yesterday and not adequate recharging, however it did turn over although slower than usual and once it fired up it didnt cough or sputter and just ran like it should. Maybe your theory on losing its prime and air somehow getting in the lines is the culprit?

is this the manually lever operated pump on the side of the injector pump? the one that allows you to manually prime fuel from the tank to the filter?


think i may have a drip on both connections their as well

That's it. Transfer pump, lift pump, primer pump: pick a name.

Yes. And make sure to leave the lever in the unloaded position.

a drip? as in a leak? one that might suck air?
