About 2 weeks ago my starter was doing the coffee grinder noise happened only maybe 6 or seven times till it just stop kicking all together. I'm new to wrenching on bikes but from my car experiences it was a bad starter
bendix. So jump on the forum. Ok so it doesn't have one. I'm learning. Looking at the many posts of this problem told my the sprag was shot. The only question was it going to be the $100 part or the $10 part. Let the tear down begin. The first issue I ran into was that I was unable to get into the small inspection cover to use a cover removing tool because the screws were seized. 😡
So gently pried off with 2 pry bars and a rubber mallet. All good. Next issue was that I was unable to use the clutch holding tool because I couldn't remove my pressure plate and rod from either side. I don't know what that's all about but I was able to use a trick I read of putting a couple pennies in the gears to hold them while I loosened the 30 mm nut. Worked great. Next was removing the alternator armature. From my reading it should slide off without a puller. Well not mine. Again back to the pry bars. Real tight coming off all the way to the threads.
So have made it to the flywheel. Pulls off nice and easy. Turn it over expecting to see something damaged. Nope. Ok so on to pulling the large c-clip and removing the sprag. The sprag comes out nice and smooth and I see nothing wrong. Reading about the spring issues I have only seen and heard of how the spring is really torn up. Mine was no stretched yes but made my question if this was the problem

After replacing the spring which was donated from a CR 19778 seal (thank you forum) I felt better about the fix.

Fits deep and tight😄.
So on to reassembly. Hadn't seen anything about the sprag being directional and didnt see the little arrow on it until putting it back in. Oops. Ok so called Ducati dealer in Bellevue Wa. for some help. Great guys, happy to help and told me the arrow goes the same direction your starter spins. That's counter clockwise. In it went. Got it all back in and went to torque down the large nut but something didnt seem right. So I pulled it back of to find the shim behind the flywheel bearing had slipped down before it was tight and got shoved into the gear. A few little nicks in it but a little filing smoothed them right off. The rest of the reassembly went real smooth. I did some other work and upgrades at the same time but I'll do another post for those.

Old twisted spring and new round one.
