Starter / Gen question
 

I was working on the 149 today and the Starter/Gen started making a lot of racket when the engine was turning over. I took the belt off to make sure it was the starter and it was. The bearing felt okay and their was no end play. While cranking the engine though I grabbed the pulley and was able to stop it from turning while it was supposed to be cranking. Sometimes when I m trying to start the tractor I have to bump the starter depending on where the piston position is. After the tractor ran for a minute the starter sounded fine and again fine when I re-started the engine. I know it is charging properly and turning over at a good rate and cleaned my connections. Any ideas? I did not think I should be able to stall the pulley! Thanks, Mark

Are you talking about the small pulley on the S/G itself?

No, it is supposed to have a square key to hold it in place. I can't imagine it could have sheared, but sounds like it's gone missing somehow. Time to remove the pulley for a look.

Yeah the small pulley that the belt rides on. It is still keyed. With the belt off when I turn the pulley it does not turn separate from the insides. Everything feels intact. I just went out and started it again without an issue.

Did you use your hand to do this,it could grab you back.Lets be safe out there.

So are you saying that the starter is not capable of overcoming the resistance you can offer with your hand?

I'd probably not try that, but since it's also possible to turn the engine over by the same hand, I'm not sure it's indicative of much. I suppose if it's very easy to stall the thing by hand you could have a weak starter.

More likely a weak battery or dirty cables (power and ground )

Have you checked those?
