Briggs Intek 31P7770348 E1 04052QZA. Picked up a nice mower For 300 a couple years ago. Now I have a starter issue. The starter wouldn't always catch and just grind. then It wouldn't even engage. Checked it out and found the bendix was totally destroyed. Went to the grave yard and got a good starter and all worked good for a day. What I found is It either grids or locks at one spot on the fly wheel. The fly wheel is part #591760. I think the teeth are worn on the fly wheel. It always happens at the same spot on the fly wheel. The teeth either don't mesh and grind or the teeth lock up edge to edge. The picture here is showing the gears in a locked situation. I have 2 junk engines.
3197770377E1 with a flywheel part number 591758 And 31f7070112E1 with fly wheel 693556 My flywheel is 591760. Can I use one of the two flywheels to replace my 591760? Please advise. Thanks , Matt.

Yes, the key way match to the magnet on both however, I believe there is a difference in the charging systems. (magnets) After more searching, my flywheel is part # 595100. I hope I can find a good used one.
 
The pictures shows there is no problem with the flywheel gear teeth. The Bendix gear is fully extended but not even close to contacting the flywheel gear. The gear on the starter gear moves up and down, not side to side.

Are you sure the starter is the correct one and bolted on tight? This does not look like a flywheel problem.
 
to me, the starter gear should be inline with the flywheel and under it when retracted. Looking at the wear marks on the flywheel teeth, it is the starter damaging the flywheel. The teeth are not going deep enough. Either the wrong starter, bracket or mounted wrong.

Starter mounted about 1/4 inch too far away from the flywheel.
