New 560 Owner

Over the weekend I purchased a 1959 560 Diesel, and have a few questions on it.
It seems to blow a lot of white smoke and misses on a cylinder or two after it is started. When I purchased it I figured this would clear up when it got up to operating temp. So when I got it home I changed the engine oil, cleaned the oil bath air filter, filled it up with fuel and hooked up my 13 ft. JD disk. I spent about 2 hrs in the field with it.
When it is under a load it cleans out and pulls on all cylinders with no white smoke. When the disk is raised out of the ground to trun around it goes back to missing and smoking??
It seems to have plenty of power when pulling. ( I think it might out pull my JD 720D) Just did not know what to check first.
Thanks for any advice!

BTW this is my first Farmall. I have been a 2-cyl JD guy for the last 20 years. I really think I am going to enjoy this tractor when I get it running right.

If you didn't already do it, change the fuel filters. If that doesn't cure it, I'm guessing it needs some injector work and possibly the injection pump needs some attention as well.

I"d keep a real close eye on your coolant level.

If it goes down at all, that"d probably be what"s causing the white smoke.

Have you changed the oil? Is it milky looking at all?

In my admittedly limited experience with Diesels, the white smoke is unburned fuel being emitted. I had an Oliver doing that once, an old mechanic told me to get it running to where it was missing and then loosen and move the injector pump a little at a time til it cleared out, and it worked ! Timing. I don t know if that will work for you, but I thought I d throw it out there to try, easy and cheap.

After you change the fuel filters, which do affect
fuel pressure, I would check the automatic load
advance and initial static timing. I have adjusted
hundreds of those load advance pumps over the
years and believe me if they are not working like
intended you would swear the engine is in tough
shape. It needs to advance two full marks on
timing window at all NO load speeds and it retards
gradually as you come under load that is why it is
called load advance and not speed advance. Static
timing is 3 degrees before top dead center. Now I
know you don't have a plastic timing window in
your pocket which is what you need to do it right,
but after doing so many I often times just do it
by ear. Above head of pump, and behind governor
housing is a bolt with a lock nut . Nut takes half
inch wrench or seven sixteenths and bolt head is
either 3/8th or 7/16. If you start her up, run it
wide open , loosen the lock nut while holding
bolt, screw bolt in manybe quarter to half turn
and see if it changes it's tune. If not, nothing
lost. Now, I am not talking about those allen
headed adjusing screw for fuel and speeds. Also,
lots of guys just advance the static timing until
it clears up, problem with that is it stays there
under load and that is not correct. There is of
course more to it than this but what I would try
first.

The coolant level looked ok when I got it. I changed the oil and it was not milky, but I will keep an eye on it.

Thanks for all the replies. I will change the fuel filters and check into the timing on the injection pump. Sound like a good place to start.
