Starter Bendix
My 76 FLH has a bad grinding sound when I hit the starter. Upon tear down I found that the starter Bendix is very rough. Not the gear teeth, but the body of it where it would ride against the back side of the ring gear.
My question is - is there supposed to be something that limits the travel of the Bendix, so the it's body doesn't ride against the ring gear, or is it supposed to push all the way out against the ring gear?
FWIW - I have 2 thrust washers in place where the shaft goes into the outer primary cover. It came apart that way, so I've always put it back that way.

Far as I know the brass washer [quite thick] is what limits travel..
Rough physically?? but it turns freely one way while not the other??
I guess I would start by inspecting the lever, or Carrier, in the primary, that carries [aims] the bendix... also ensure you have the correct width spacer [brass in primary on bendix shaft] number is Not as Important as Width...

so, does the Bendix travel far enough to come into contact with the back side of the ring gear? I know the Bendix gear mates to the ring gear, obviously. Not sure what brass washer would go between the Bendix and ring gear.

the "face" of my Bendix, the flat part behind the Bendix gear, is all chewed up. Not sure what the back side of the ring gear looks like. It seems like these two surfaces come into contact with each other when engaged. Not sure why/how the Bendix surface is chewed up.

Does your bike have a stock outer primary? I ran into a similar problem on my '68. The bearing that the starter shaft rests in the stock outer primary is flush with the mating surface of the primary. On the aftermarket outer primary, it is recessed. When the Bendix is engaged, it can travel further, hitting the back of the ring gear. If this is the case, you'll need a longer end on your starter shaft. I may have one in my parts stash.
