Ford Jubilee Question

I'm looking to convert my Ford Golden Jubilee to 12V from 6V. I'm finding kits to do the conversion, but it looks like the kits
for the Jubilee are different than the kits for the NAA? Except for some slight and mostly insignificant differences, I thought
these tractors were mechanically the same? Will/should an NAA conversion kit fit on a Jubilee?
 
The NAAs were built for 2 years only - 1953 and 54. A Jubilee is an NAA. They were just built in 53 - the Jubilee (50th) year of Ford Motor Company.
This website is a very good place to buy parts for your tractor.
They have competitive prices, good customer service and they host these great, Free forums.
 
As UltraDog said, a Jubilee is an NAA. NAA was the official name of the model. The "Golden Jubilee" name was a marketing name used to tie it into the 50th "Golden Jubilee Anniversary" of the Ford Motor Company for the 1953 model year only. The NAA was actually made from late 1952 through 1954, and the late 1952 tractors were part of the 1953 Golden Jubilee model year. There are a few slight part differences between the two model years, like the nose badge, but when searching for parts on the parts site you need to use the model name NAA for both years. They also made a model designated as NAB during the same time period, which was the same basic tractor as a NAA but its engine was designed to run on kerosene instead of gasoline.
 
For your voltage conversion purposes they are the same NAA tractor as noted by others. The later ones had a better hydraulic pump. Don't forget to include the light bulbs, if you have lights. Don't trash your original 6 v. bulbs. Someone will want them.
 
You don't need to buy a kit. Just go to your local car parts store and by a delco remy alternator. napa sells them around here for around 50 bucks. you can use the existing wiring to wire it up unless you can see some bad wiring. you can remove the voltage regulator as you will not need it as the alternator has its own voltage regulator in it. I have converted over several tractors from 6 volt to 12. just have to make sure the wire coming from the alternator goes through your switch so when you shut off the switch it will stop any current flow.
 
Thanks pinball for the information. Is the link I've attached the correct altenator? What about a mounting bracket for the altenator? Will the pulley on the altenator work or take the one off of the generator? Also, change the coil or just buy a $5 resistor? I thought about just doing it myself but

(quoted from post at 06:32:10 02/07/18) The alternator kit is less than $90 and includes mounting brackets and the correct, wider pulley. Time is money - Once you purchase the correct pulley, fabbed brackets, and figured out wiring mods you will have easily invested more than the $50 difference of the kit.

That's my sentiment too Dollar Bill. I would also use a 12V coil.
NAPA IC-14SB or equivalent that does not require an external resistor. Less than $15 here.
The added resistor is just another thing to mount and more connections to corrode and fail.

I couldn't agree more - Life is so complicated, we need to simplify at every opportunity.

Wonder why they even make a coil that requires an external resistor?

eeps a lot of 'killer' heat out of the coil AND allows starting boost to spark on so equipped machines.
 
that is the correct alternator. I think the pulley is the same but if you take your generator off and take it with you they probably would take the pulley off the generator and put it on the alternator if it was different. normally you can use the same bracket. due to the alternator being shorter you may to put some spacers on the long bolt to get it tight. make sure your amp guage works. it will tell you if its charging okay.
