I've got an allis C which was converted to 12 volt many years ago. I've got it down to fix the clutch and ring gear on the flywheel. Does the 12 volt battery cause the ring gear to wear out quicker. Is there a way to use the 12 volt battery and charging system yet get a bit less kick to the starter? No I don't want a 6 or 8 volt system.

I think that is a pretty much yes/no/sort of thing. I have had tractors that where 6 volt but are now 12 and never had a problem but yes some hit harder then others do and seems like if you use smaller battery cables like what is on a car that that helps a tad but that could also be one of those things that just seems like it helps but does not
One of the down sides of keeping a 6 volt starter when you convert to 12 volts is the higher kick in torque and RPM which can be a bit tougher on starter drives n gears etc.
Couple things that can help are to use a lighter duty lower CCA 12 volt battery (they will still give good starting) or like Old mentioned maybe use lighter gauge battery n starter n ground cables
Id use light lithium lube on the gears n drive etc.

LOL funny how like minds think the same. Found out years ago if you switch to 12 volts use 12 volt battery cables like used on cars and trucks so you have a lower amp rating going to the starter so that in turn slows down the thump when you hit that button

John is you would be so nice as to send me an e-mail I have a legal question for you which if you answer I would in no way hold you to it just one I would like to sort of know where to go from where I am at

Short answer: "no"
But if you still have the original ring gear on your tractor, I'd say it's on borrowed time.
Now a 12 volt conversion is going to have a LOT more torque than the original starter, but your engine will start much easier so I'd expect it to spend less time cranking. Most of the ring gear wear occurs when the starter first engages, and that's not going to be affected much by the conversion. The increased torque comes to play AFTER the starter is engaged.

If you're using smaller cables to slow down the starter, you need to watch the temp of the cables and starter when you're cranking. You're using the extra resistance in smaller cables to drop the voltage at the starter, that will result in the cables and starter heating up more rapidly than with the correct sized cables. So be real careful of long cranking times...

Automotive cables and the smallest CCA battery you can drop in will take care of it.

Ya it would be nice if I could be 100% sure if using the smaller auto type battery cables do in fact make a starter hit a tad bit less hard or not. I know it sure seems to work that way but just because it seems so does not mean it is so

Ya the starter does in fact turn faster but if you use a small auto type battery cable it seems to add resistance so that in turn slows them some but as I said seems to do that do not really know if it really does or not
It may drop when the starter is cranking but the starter will hit at a high speed because current drain is low, 60 to 80 amps until it starts turn the engine.A shop that does starter rebuilds here puts different brushes in 6 volt starters that are used on 12v conversion. Cost 100 bucks.
