Jubilee diesel

Hi there, recently bought i jubilee diesel 4 cylinder it sure in the year
someone painted over the tag having trouble with starting. It only
starts with starting fluid. Warm or cold it cranks and cranks if you
don?t have starting fluid any ideas ?

Thank you
 
The diesels came out in about 1958 I think.
So as Larry above said it wouldn't be an 800 either. It would be an 801.
To a non Ford guy they all look about the same but it's like calling a JD 50 a B or a 560.
Those are all similar to the untrained eye but very different if you need parts or service for one.
 
(quoted from post at 12:28:06 04/29/20) Never saw a Jubilee diesel, they were gas only. Probably a 600 or 800 series diesel with injection pump trouble..

Actually, Jubilee's were available with a gasoline engine (NAA) or a kerosene engine (NAB). In 1953 both the NAA and NAB tractors had the golden jubilee medallion on the front.
 
(quoted from post at 16:46:52 04/29/20) Does anyone know what the problem might be with the injection
pump ?

If it runs after using starter fluid to start it the issue is likely low compression rather than anything wrong with the pump. If it won't stay running after the shot of ether then it could just be that it needs to be bleed or it could be the pump or the injectors. You need to figure out exactly what model it is and then get the proper service manual and follow the troubleshooting procedures in the manual.
 
May or may not be the pump, could also be slower than normal cranking speed. My 871 was not starting right, starter bushing wear was allowing armature to contact field coils slowing cranking speed. Battery and cable condition is critical as diesels need 200 RPM cranking speed. If engine has had poor fuel filter service that can cause severe hydraulic head wear, which lowers starting fuel delivery.

Be that as it may, what's it have to do with identifying a diesel?

I was responding to the statement "they were gas only".
 
(quoted from post at 22:20:27 04/29/20) Nothing, all I mentioned is that I didn?t know what year it is it is a
diesel 800 jubilee

A "Jubilee" was a marketing name for the 1953 NAA & NAB model tractors because that was the Ford Motor Company's 50th anniversary, and any 50th anniversary is sometimes referred to as a "golden jubilee". The NAA & NAB models were only made from 1953-1954 and only the 1953 tractors were referred to as "Golden Jubilee" or "Jubilee" tractors. The 1954 model year tractors were just called NAA and NAB.

After that, starting in late 1954 for the 1955 model year they began making the "hundred series" tractors, there were the 600, 700, 800 and 900 series of tractors, and each series had various models that were differentiated by the middle digit in the model number, and the various models had different transmission, PTO and 3 point hydraulics options. In the 800 series there were several models, which were the 820, 830, 840, 850 & 860. None of the 800 series tractors were ever offered with a diesel engine. The hundred series tractors were not Jubilee tractors. Starting in 1957 for the 1958 model year they started making the '01 series tractors, the 501, 601, 701, 801 & 901 series. The '01 series were the first Ford branded tractors offered with a diesel engine. The '01 series tractors were not Jubilee tractors either.

So if your tractor has a diesel engine, it is not a Jubilee, and it is not an 800. It could be an 801 series, of which there were even more models than in the 800 series due to the addition of the Select-O-Speed transmission. The models in the 801 series were the 811, 821, 831, 841, 851, 861, 871 & 881.

Does it continue to run after you use starting fluid to start it? If so, then the problem is likely to be low compression, so I would do a compression test. Continuing to use starter fluid to start it will most likely damage the rings, and possibly the pistons, and cause it to have less and less compression over time until it won't even start with starting fluid.
 
A diesel 800 Jubilee is kind of like a Ford selectOmatic transmission. They don't exist.
Calling it that doesn't tell us much except that the guy who asked about it doesn't know - or maybe care - much about Ford tractors.
For all we know you Could have a diesel 600 jubilee which has a different engine than the diesel 800 jubilee.
 
Thanks for the Info, yes runs like a top after starting however I think it
may be an electrical issue? My battery went bad and I put the
charger on it and I killed it and started it about 3 times without ether
because it had the power to start ? Maybe I need to convert it to 12v
? I agree with the series as wel anyone could have put a 800 series
sticker on there
 
(quoted from post at 07:03:31 04/30/20) Maybe I need to convert it to 12v
?

Say what??? All Ford diesel tractors were originally 12 volts. If you have a 6 volt battery (or anything other than a 12 volt) in that thing, it's no wonder you're having starting problems. It's OEM configuration was 12 V negative ground.
 
Yes, many parts have been swapped around and incorrect decals and nose badges have been installed over the years on many old Ford tractors.

If it starts without ether when you jump start it then the electrical system may just not be turning the engine quick enough to get enough compression to start otherwise.

You say that the battery "went bad". Does that mean that it will no longer hold a charge? If so, have you already replaced it?

You also say "Maybe I need to convert it to 12v?". That tractor (or at least the tractor that engine was in when it left the factory) had a 12 volt system when it left the factory. Only the pre-1965 gas engine models were 6 volts.

So if it has a 6 volt battery in it now that is likely part of your problem. You should check the charging system to see if it is putting out 7.3 to 7.5 volts (proper for a 6 volt battery) or 135.-14.5 volts (proper for a 12 volt battery).

Once you have the proper 12 volt battery and charging system installed and working, make sure that the battery cables and the cable from the solenoid to the starter are good and that the connections at both ends of all of them are clean and shiny, as well as where they connect to. Once you have all of that taken care of the starter should spin the engine fast enough to get good compression and it should start without ether.
 
(quoted from post at 08:19:32 04/30/20) I have a 12 v battery in it it appears to have the old 6v generator on it
tho

They used a 12 volt generator with an external voltage regulator. Looks similar to the 6 volt charging system on the gasoline tractors of the same time period. You should measure the voltage at the battery when it's not running and when it's running and post the results back here.
 


Since you say that it stated well when you had a charger on it that pretty much is your answer right there. Diesels need RPMs in order to produce the needed compression to make the fuel ignite. They will crank all day without starting if the speed is not adequate.
