Well, I've never heard of this or had this problem when converting to 12 volts. I thought the idea of switching to 12 volt was to increase the force or power of the starter and spin the engine faster for easier starting? Anyway, please use your own discretion.

I have been using a 12 volt battery for 5 years now. It was already in the crawler when I bought it, so who knows how long it was in there before that. They were using a 12 volt fuel pump also. It is an OC-4 42 with IXB3.
Just had to charge up the battery before hand , for a few hours and it would start several times before needing a recharge. Works pretty good most of the time.
Til this spring... the battery is showing it's age and I stalled the crawler way down in the woods ... in the swamp.
Battery was dead. I said a few choice words.
After getting the truck stuck getting near it and taking the battery out of the truck to jump start the crawler, putting the battery back in the truck before pushing the truck out of the mud, (more choice words) driving the crawler home home, walking back down the woods to get the truck (more words) I decided that enough was enough.
Time for a charging system.
Now I have an alternator out of a Toyota pickup installed. Clearance is pretty tight but it will fit without cutting any sheet metal. Brackets were pretty easy to fabricate. The only foreseeable problem is with the pulley setup. Won't know for sure til I start working it hard and things get bounced around.
Seems to charge pretty good. Changing from positive ground to negative wasn't an issue since I have mag ignition and no other accessories. I will try to post some pictures when its done. Some hints on linking pictures would be a help. Thanks

Blake:
I may have not made myself clear when I stated the above. If the gears do not mesh properly, when the starter is engaging, there is a chance that the starter bendix will knock the ring gear on the flywheel out of align, causing it to not rotate true, but wobble as it cranks . this could bind or bend the starter shaft and bendix assembly. I belive the ring gear is only a press fit on the flywheel. the 12 volts will defenitly have more torque and spin the motor faster and easier for better starting, which is a definite plus. the force i was refering to is in the action of the bendix gear engaging into the ring gear. hope this clears up any confusion.

I understand tcr... but I have never heard that happening. I would think the bendix sliding in under 6 volts would do just as much damage if the teeth land on top of each other. If you've had problems with the gears jamming, maybe the pinion gear is flat on the ends and needs replaced. I think this would be a mechanical problem, rather than one that would hinder me from switching to 12 volt.
I did one have a ring gear knocked off the flex plate on my Bronco with an automatic. It had little induction welds all the way around that did not hold. I managed to get the ring gear back on and welded it in about 8 places and it never gave any more trouble.
