Converting WD to 12 volt

 

 

Removed the generator. This WD has a 1/2" fan belt. Not sure if that's correct, I thought they were 5/8"?

 

 

Drilled out the 5/16" holes in the original mount, to accept some 3/8" ready rod.

 

 

I was told, your original pulley will work with this alternator. Shaft size looks the same, not sure about pulley thickness because I didn't have to swap mine.

 

 

Got it set up on the bench, and cut the rod to length.

 

 

Mocked it up on the tractor. If you redrill the 2 mounting holes about 1" ahead, it fits right in, and the top bracket needs a slight adjustment to line up nicely.

 

 

Wired it to the battery. It is supposed to be a one wire alternator, but there is a ground stud, so I ran two wires. that way I am sure of a complete circuit, and don't have to worry about all the different bolts and connections on the ground side.  Put a coat of flat black on it so it doesn't stick out so much.

 

The whole project took about an hour. Shoulda did this years ago, will definitely be doing my other one in the near future!

 

 

Thanks for looking.

I converted my 1955 Ferguson TO35 from 6v to 12v and made the tractor so much more reliable. My 6v 1952 AC WD seems to start so far but if it gets ornery I'll switch it over. I used one of the small 12v alternators the 'hot rod guys' use as it's smaller and fits in the frame of the ferguson (the typical Delco models can get hit by the steering drag link going through ditches. The Farmall cub+ guys also use this hot rod alternator because they have to tuck it up under the cowl.

You'll find it's an amazing+ tractor now.

Just a note: if you add silicone dielectric grease at all connections after polishing them up you'll greatly increase the longevity before corrosion gets in there.
