Reversing the direction of a starter generator???
 

I just bought two cub cadets real cheap and the starter generator was off of one of them. I just jumped the s/g to make sure it works and it works but it spins the wrong way! Is there any way to reverse the direction of it or should I try to sell it and buy another one?

Not a 100% sure but I think you would have to replace the field windings in the s/g to make it run in the correct direction. Might be cheaper to find a good used one.

It would be the best, in the long run, to sell the one you have and obtain the correct S/G for a Cub Cadet.

Agreed, I would just sell it and try and buy one that is right for the cubs. I've got one off an old Economy Tractor sitting on my shelf that spins the opposite direction of cubs so there are still people wanting them out there.

JD 110 are reverse from cubs also i believe

Pretty much everything except the CCs use a CW S/G.

darkminion 17 was looking for that starter 5 days ago.

the s/g on my 64' simplicity has the same one as my cub...but different rotation also.
Technically, you can put the shaft through from the other side and it will reverse the rotation....but then I don't think it will bolt on to the engine in the right place.

The biggest roadblock I saw is that the brushes are slanted in different directions. I think that is the main difference between CW and CCW. Probably only an endplate difference, but I gave up checking any further. I'm down to one now, the one on the tractor. Hope it hangs in there....

I recently tore down the 126 to use for donor parts for my 122. The 126 was wired positive ground (!?) and it worked!! The S/G worked in a correctly wired system (and one wired positive ground!). That was a weird one I may never fully understand.

The field coils, brush holders, and pulley-end casting are different. There are also 2 different length starter/generators.

Okay ,Matt you are right there are 2 different sized S/G
I have found a cw s/g
Easton ct.how do you flip it ?

Technically, you can not put the shaft through from the other side... There are no brushes/holders on the other end and the shoes would not line up with the armature.

That's what I mean by "technically".
I've done it with either a 110 motor, and/or an automotive starter. I remember telling my friend he was sol and then he did it and it worked.....I was surprised, and sure enough it works. But again, all depends on the starter.

I am pretty sure you can wire a negative ground tractor, positive ground and everything will function correctly except!! the voltage regulator will be fried near instantaniously. Seen this happen on large tractors a few times. Starters spin correctly ignition functions, doesn't charge.

The direction can be changed,i have had it done,if fact the starter on my 123 is from a sears suburban.I did not do the work,but the guy who did changed the direction,and rebuilt it for about $60.The cubs are a bit odd,because most of the time it is normal to have the s/g on the flywheel side,but because when IH put the gear reduction on the Cub transmission they had to put the engine in backwards.
