Starter question

[b:1a2b876598]I have a TO30 that has been converted to 12 volts, it has a 6 volt starter, it went out yesterday. Should I update it with a 12 volt or stay with the 6 volt, pros, cons [/b:1a2b876598]
 
The 12 v. starter will not turn engine over quite as fast as a 6 v. starter using 12 V. system. If your engine does not start almost immediately it sounds as it needs to be tuned correctly. Then you can use the 6 v. starter without worrying about it going out on you again. If it does not start immediately you should use the 12 v. starter. I am figuring this on the TO engines as I am not up on the TE series.
 
Starter "went out". What does that mean??? Maybe all it needs is a new set of brushes and the commutator undercut. Maybe new bushings.

If field coils and armature are ok then just rtebuild the starter with new brushes.

So it actualy depends on just exactly what INSIDE of the starter "went out". 6v on 6v and 12v on 12v can "go out " too.

Take it apart and determine what is really wrong.
It ain't rocket science.
 
All my old 6 volt starter tractor are now 12 volts and the 6 volt starter is still on them. Any starter will sooner or later go bad it is the nature of how they work and the brushes wear out. The key to not burning them out fast is not to spin the engine over more then a minute at a time and then give it a break for 3-5 minutes to let them cool
 
ALL starters go bad sooner or later and that is just the facts of life. Ya maybe a 12 volt one might last a bit longer then a 6 volt one but either way they go bad. All my tractor that have been switched to 12 volts have 6 volt starters on them and have for decades and still doing just fine. I have more them 30 tractors by the way
 
Up grading the field windings to 12 volt on your original starter would be the best solution.

Not the cheapest, but it will let you keep the factory starter.

The problem with running a 6v starter on 12v is it slams the drive too hard. Prone to break the drive, the nose cone, the flywheel gear, and on that model it can knock the flywheel gear of the flywheel.
 
[b:c7e575ed56]Thank you for the replies, when I meant the starter went out is that will not spin over, I can pull start the tractor but will not turn over via the starter. I put the jumper box on it and it has a short in it as it started to melt the battery post. I noted a little while back sluggish starting first thought battery but it was new and no issues, also noted that when i would first start the tractor the amp gauge would stay pegged on the positive side while running even when I shut it down for 2-3 minutes. No one in my area builds starters anymore, dying trade, so I opt to purchase one as I use the tractor on a frequent basis. I have replaced the flywheel ring and clutch about a year ago and the starter is only 2 years old. I believe my best choice is to upgrade to a 12 volt, will i need to change the nose cone or is the length the same?[/b:c7e575ed56]
 
Check with your local parts store and see if they rebuild starters, or you may still have an auto electric service locally. As others stated there is
no problem with the 6 volt on a 12 volt system. Faster spinning is a plus.
 
That can have a couple different starters.

This page has them, look toward the bottom, it tells how to measure and compare.

Note the price difference in the new and rebuilt.

The new is China/India.

The rebuilt is OE.

Another choice would be find a reputable rebuilder, ask what a set of field windings would run, ship them your starter.

Sounds like you may have a short some place other then the starter. If it where me I would take the starter to an auto parts store and have it tested and while your at it have the battery tested also both test are free by the way. Guessing is not the way to do thing trouble shooting is the way to do things.
 
When connecting the cable to the starter it's important to not allow the stud to turn as the inner connection will short. It should have a nut underneath to prevent that from happening.
