Well, I read what you wrote and what I wrote, checked the instructions again and got a panic attack!
I didn`t put locktite on the main nut.
Obviously like you say the splines shouldn`t be showing. I think it went a bit quick when I whipped in mine because the clutch was sitting a little loose.
Luckely, no harm done and I also had to shim out slightly more than with the one that was in there before.
I`m sorted too now. Glad you posted because that could have been a very silly mistake on my behalf
