have 1952.. generator not putting out, wire insulation breaking away, now is the time to make the switch,took 4 hours to get the alt. bracket right( thank you china )ammeter doesn't have terminals, is feed through, any suggestions..Bill
 
hillbill,The ammeter will work with your new alternator,you will just have to run the alternator wire through the inductive pickup the opposite direction as it is now.
 
Hillbill, eh the alternator brackets are mostly junk.I fab up my own brackets when needed,much better looking/fitting brackets.By the way,be sure you use a 5/8 wide pulley on the alternator.
 
Why didn't you just get the GEN rebuilt at a reputable shop for a lot cheaper than going over to 12V? What do you plan on doing with OEM GEN, VR, and Bracket?

If new pulley is for 1/2" wide belt:

Unbolt wrong pulley,

I did mine, and my 850, with the kits from the site, which only cost a little more than the alternator alone, fits and works very well, with correct pulley. The alternators also charge right from idle, no need to rev them up to get them going. The 8N was a one-family rig from an orchard in Calistoga, and has 1100 original hours after doing 100 hrs of mowing last summer. The original charging system quit, and the wiring was getting a little cheesy, so the kit was the way to go for functionality. My gramps showed me one of his favorite tricks when I was about 10, he had three deuce n a halfs with the REO engines as lime spreaders, came 24V, he converted them to 12V, but then he would use a 6V starter as he had a pair of '51 REOs and a pair of 53s, and they would spin great, and starter life was also great. We also had an 8N that was a lime loader for years, Mercury flathead piston kit and step-through Wagner. That and a 53 Chebbie ton truck that delivered coal both got 8V batteries with turned up regulators as they had to start in the NY winters, and it worked great, but drives the "purists" nuts. On both my 8N and 850, I removed the whole original system, wiring and all, and boxed them up in case I ever sell them to a "purist". All new heavy guage and sheathed wiring on each, 35 series batteries fit very well- not even any new holes drilled, completely reversible to stock. Both spin fast, start instantly, and no more row-row-row lol. Purists are sharpening their daggers now
