Thanks to all the posts in regard to my earlier post "615 starter noise". I removed the starter and inspected the drive gear. It appeared to be engaging about half way. I noticed that the entire assemble was sliding backwards and forwards alot. I took apart the starter (This is a rebuilt starter by the way) and inspected and lubed the bendix to make sure it wasn't sticking. I noticed that the bearing plate (large plate between bendix and armature) had a new bushing installed, but it stuck out the front side (towards cone). This was allowing the entire bendix/armature slide backward and jam into the back cover plate of the starter. I think that if the press fit bushing was sticking out the back side of the bearing plate, (keeping the whole assembly forward), this would be the fix. I didn't want to mash up the bushing however, so I put a washer between the bearing plate and the armature. Put starter back together, and whizzzzzz! No noise and motor turns over super fast. No ether needed! Go figure... I hope this helps someone in the future. Thanks again for all your help. I should have taken a pic and posted but I was having too much fun digging out a stump, then moving around firewood in the loader... Eric

On the back side of the amature at the end plate there should be a thrust washer to prevent end play if the unit is assembled right. The armiture should not have any real play or slop end to end . That center bearing plate is to keep the long armiture shaft from deflecting from magnetic field created stress.

I don't know why there was play, and there was a washer behind the armature (still is) as well. Something was binding and was eliminated by adding the washer, when I got the tractor before I had the starter rebuilt it was doing the same thing, "rebuilding" it didn't correct the problem.. I really don't know exactly whats going on... but it works. If I ever have money to burn I'll find salvage starter, take it apart and compare the two.

The only "lube" on a starter bendix should be graphite. If you put grease or oil of some kind on it, you might have trouble down the line.

Yes, you are correct. I did use graphite-I read that wet lubricant would attract dirt over time when researching starter issues. What about the bushing position? If it were sticking out the rear side of the bearing plate it would have had the same function as the washer, I don't know. Anyway the tractor starts great now. I've ordered a new mufflerand wil be replacing some hoses. Whats nice about this project is it is 100 percent funtional in the mean time while I get it back in better shape.
