Case 580SE not restarting after running

D21S-5 · Dec 8, 2021

Case 580 SE starts from cold every time, even after sitting for a week. After running for any length of time and shut off, it will immediately start back up. If it sits for say 10 minutes or more it will not start. It turns over fine, has a new battery.

When it's warm & not starting, try loosening the 10mm bleeder screw at the fuel filter banjo fitting.
If it has some residual pressure when you open the bleeder, close the bleeder & try to start the engine after that.
Let us know if that allows it to start.

Thanks for the reply.
Interestingly, after I posted, I cracked open the drain on the bottom of the secondary filter and it had pressure. It started right up. Ran it for a bit, cut it off and it would not start back. Opened and closed the drain again and it started.

Thought it might

I've seen this a few times now.
You will need to replace the fuel shut off solenoid in the injector pump.
For some reason, the solenoids must get tired & refuse to pull the plunger to open up the fuel supply to the pump - at least while that little bit of pressure is present in the fuel system.
Fit a new shut off solenoid & should work normally again.

Thank you ALRMAN.

Revisiting this issue. I have replaced the shut off solenoid , twice. This machine had a new battery in it so I didn’t realize the alternator wasn’t charging at first. Had the alternator rebuilt, which also fixed the hour meter. Still no tach btw.
Still having the no start issue. Just like before, starts first time and runs fine. Will not start back unless I open the bleeder.

You've got to have good current and voltage at the solenoid for it to work right. I have a JD backhoe that had the same problem. Would not restart hot after sitting a short time. Ended up being a bad connection on the hot wire going to the solenoid. I reworked that connection and it hasn't happened again.

Bummer!
When you replaced the shut off solenoid - you fitted the new plunger & spring? Not use the old ones?

D21S-5 · Feb 20, 2022

JL Sargent, I had a volt meter hooked to the stud on the solenoid. I have 12 volts with the key on and about 9.5 volts when the starter engages.

D21S-5 · Feb 20, 2022

Alrman, yes, new plunger and spring. The seller sent me a second solenoid. Same thing.

alrman · Feb 23, 2022

I'm curious if you could rig a second battery just to the solenoid - so it had a full 12V supply while cranking & if it makes any difference?
edit - (just as a test procedure)

Just remember to remove the connection when you want to shut the tractor down.

D21S-5 · Feb 23, 2022

I have been thinking I would run a ground to the case of the solenoid and maybe use a radiator clamp to hold that and disconnect the hot wire and run a wire directly to the battery positive. I would do this after I had done the initial start and warm up. I will update the post when I have done this. Thanks

check return line and fitting from inj. pump to tank if not flowing will build pressure and won't run

D21S-5 · Feb 23, 2022

What would be the best way of checking that?

alrman · Feb 23, 2022

The blocked return line fitting scenario is not applicable to the CAV injector pump on the 580SE cummins engine - only the Roosamaster pumps of the earlier Case 207/188 engines.

D21S-5 · Feb 23, 2022

Ok, thanks.

Edit:: ALL RoosaMaster/Stanadyne pumps that have a check ball return connector.. Case, JD, Continental.. on & on..

Update: I connected the shut off solenoid directly to the battery (positive and negative) and same issue after initial start up. I cleaned the relay connections and swapped them around, as they are the same, and still no start ( which was no surprise) . It would sometimes start back up 2 or 3 times, but there was not anything I could say was consistent with why it would start. Today, just to eliminate everything I can think of, I took the return line (very small metal line on top of injector pump) loose and where it transitions to rubber and blew it out. Fuel immediately came out of the rubber hose that goes back to the tank before I clamped it off, so no restriction there. Didn’t make any difference. The day I went and looked at this machine, we started and stopped it several times. Same thing the day I had it picked up and when I got it unloaded and parked, went to start it back up and that’s when this all started.

I am trying to remember but do not know if this could be related, many years ago I had a problem with an E that the fitting at the injection pump mounting flange failed, I believe it is a restrictor fitting and loose parts were blocking the flow, a new fittin resolved my issue, something to look at.
