9N starter troubles

I got a new Chinese made starter drive and put it in. When I tried to crank it, it just clunked and would not turn over. The battery cable connection got hot and smoked.

I took off the starter again and the new bendix had broken on the motor end where the main sleeve is crimped and flared out to hold it all together.

It also looks like the starter shaft is bent a little.

It has been converted to 12V and I wonder do I need a 12V starter or did I just have some bad luck with the new chink made starter drive?

Maybe the new starter drive was hitting the inside of the housing because it was hard to get the starter loose from the engine which never happened before.

Where the drive broke would not be caused by any sideways pressure, only pressure on the moving parts pushing toward the starter would have done it. Or maybe by forcing the starter in the hole while something was hitting the drive.

It was snug getting it in which never happened before and I had to drive a screwdriver between the starter and the housing to get it out.

1) They no longer make OEM bendix drives, sometimes you can be lucky and find NOS but most of us are not that lucky.

2) They sell a "replacement" bendix drive that requires a "new" mounting pin hole to be drilled into the starter shaft about 1/2" closer to the starter motor. Right now, I don't remember the exact dimension, but it should be included with an instruction sheet with the starter bendix. If you do not have this closer hole, your bendix drive will bang the flywheel ring and if it is being driven by a 12 volt battery, serious damage can result.

3) There is a new and improved starter drive available for N-Starters called a clutch drive. You often have to specifically tell your parts person about it and insist that is what you want. It does not require the "closer" hole.

4) NEVER EVER OIL your bendix drive, it is made to run dry. It will gum up and slow down the screw extension and then you will grind your flywheel ring and pretty soon the starter gear will not mesh with the ring gear and then you will have to split the tractor to fix the ring gear.

Generally speaking, one of the principle reasons to convert to 12 volts, is to spin that ol' 6 volter starter faster. Just don't crank away for minutes as this will over heat your starter and burn it out. Normally, I would not suggest even trying to find a 12 volt starter for the N-Tractor, you're on your own there.

The only good news is there is plenty of empty space inside your clutch housing and therefore most tractors owners don't worry about carrying spare parts down there. (grin) ..... ....Dell

I left the key on over night and fried my 12V coil. I ain't buying a new one. I will go back to the 6V coil and put the ballast resistor back in.
