    Posted: 10 Apr 2010 at 10:05am
The previous owner of my WD said that he converted the tractor to 8 volt from 6 volt so if I want to switch back to 6 volt what are the things I am going to need to change, I was told the generator needs to be tweaked but when I took it to a shop they said it was made to crank both 6 and 8 volt.  Thanks for you help...  John

All you have to change is the battery.
Really does it matter if you have a 6 or 8 volt battery.
I think the 8 is the way to go.
The 6 volt generator will charge it just fine.
Many people with 6 volt systems have gone to the 8 volt battery.

I never had a problem with the six volt generator on the tractor charging them.
You can also get the 8 volt Battery Tender.

If your WD has only a cutout (usually round package) and thus a three brush generator, it will charge an 8 volt battery fine. Lamps won't last as long though. And going to 8 volts on a 6 volt system is paying out money for an odd battery, rather than properly maintaining the 6 volt wiring connections, particularly those at the battery posts and the starter. And that must include the battery mounting. Battery to starter cables must not have been replaced with some from the Wallyworld battery kiosk that are for small engines on 12 volts and have way too little copper for a 6 volt starter.

Worn starter bushings are another reason as well sa bad cables or connections to ground .The 3rd brush may need adjusting but try it first.
 Other option is convert to 12 V and go with alt or 12 V gen

Oh, yah. I have trouble with the local auto electric shop, they don't want to do bearings in a starter, but will when I insist. I had that problem in a 8N starter long ago. New bearings and a new bendix and it worked fine. The thrust of the gear, plus magnetic pull will move the armature to the side in worn bearings so it can rub on the pole pieces. When it rubs it dissipates all its power there instead of turning the engine over. Brushes wear out with a few decades of use too.

As the guys posted, the use of an 8V Battery is an investment to make up for poor or worn out parts. Tired starter motors, old wiring & cables, etc all are troubles for any system, but the 6V system and its components in general need to be in tip top shape to do the deed and you won't have any troubles. The 6V Gennie will work fine charging an 8V Battery. In most cases, you won't even have to mess with the third brush if so equipped to compensate your charge rate....

I had a WD that the engine was rebuilt. After that if you stalled it while working it hard, such as plowing, the 6 volt would not turn it over very well. 8 volt battery fixed that.

I figured the raised the compression with the rebuild.
