My genny is shot on 8n(front bering loose, and <
br>magneticaly locks on motor test). Does this sound like
something I can fix myself, re-built gennys are
expensive (around$300), or should I convert to 12 volt?

Any thougths would be apreciated.

Thanks,
Joel

One of the reasons I converted to 12v was the fact that my generator was shot. A couple of considerations for me was that I had no way of jump starting a 6v tractor (remote location-no hydro-no battery charger),12 volt battery easy to replace as I already had a handful of them around. Since the conversion my tractor is much easier to start. Mind you the conversion process also saw a new coil and starting relay installed. I'd say that unless you are wanting to maintain your tractor in original condition, you should consider "the change".

Cheers, Erik

if you have the BIG generator, List on that Genny is only $113 from a NH dealer. I just looked it up in NH software #8N10000BLPR. Real NH quality, no wiring to replace, and you know it will last longer than $39.00 worth of used alternator parts. Brushes, bushings, bearings, field coils and armature all 100% NEW. If you don't really use your tractor that much, you might be ok with a NAPA alt, but keep in mind, automotive stuff is intended to be used for shorter durations.

Only my opinion

There are three 3 reasons I can think of to fix the 6v generator: first, converting to 12v will cost more, secondly, you do not gain a thing by converting to 12v as to bettter performance, quicker starts, etc, and thirdly, just do an archives search to see the number of requests for help to fix a screwed-up 12v conversion! Now, one of the great things about this board is that you already have differing opinions on this subject, and will likely get more!

I'd say...buy a conversion kit and get it right! (But save the 6V stuffs so you can put it back in the future!) Sure, a well-maintained 6V system will work. So will a well-maintained crank system! But 12 V is the modern standard, 6V stuffs are getting harder to find, etc. As a certified Hater Of Change, I'm going against my nature by recommending this path, but it depends upon just how you want to use the tractor. Sure, for a show tractor, stay with the stock system. But for a daily worker, 12V is the only way to go! I did it to mine several years ago, and it starts faster, seems to run better, generally a better tractor. (Also replaced the ignition with electronic, but that's another story) Yep, I stashed the 6V stuffs in the barn, so I can re-convert back to orig (Or the next owner can, when I'm gone) Some things I'm a traditionalist, but not the electric system. Of course, I will fight to the death for anyones right to their opinion, so it's up to you! My 2c worth.

Hi Joel,

You've gotten some good advice already. FYI, I paid $39 + tax for a remanufactured GM alternator for my Jubilee. If you can fix your 6 volt gen for a reasonable price I'd do that. If you want to convert to 12 volts, there is plenty of info in the archives to guide you through it. Of course, you'll have to consider the cost of a new 12 volt battery too. HTH. Rick H. GA.

Joel, The generator is very easy to fix and cheap. I just did mine, cost $20. Make sure if you have a threaded pulley that you unscrew it rather than use a slide hammer and bend it like "someone" I know.

Not sure where you are getting those prices from.. but our local napa can get a new 'indian' genny for 200$ or so. Also.. I've seen rebuilds on many sites int he 150$ range.

I've had my 8n genny, and a NAA starter completely rebuilt from ground up at the local mom-n-pop starter place for 80 bucks each..and that included a new vr for the genny.

If your field and armature are salvagable.. all that leaves are bearings, and bushings.. and a few misc parts.

I'd pull it apart and see if the shaft and housings are OK and decide after that. They're pretty easy to overhaul if you've got parts to work with. A good auto electric shop can probably rebuild it fairly reasonably for you if you aren't comfortable doing it. As to whether to convert to 12V, that's up to you but I have 2 6 volt tractors right now and one 12 volt and have no preference. The 6V ones work as well as the 12V. Your call.
Good Luck, Lee
