One way /tail drive pulley

Hi nitro lovers,
I had a hard thime to remove one way on the third
Mainchaftblock, I think the tolerances are a little to narrow?
What I also noticed is that there is no chim between the one way(4876) bearing and the taildrive pulley(4873).
On the 690 there is one.
Because off that I had a verry hard thime to desasembe the pin that hase to go threw the mainchaft holding the alu pulley that was wearing in and blocked on the mainchaft.
I put an litle chim between one way and pulley to fix the problem.
I came to this constatation because my one way was blocking after every flight.
After I loosen the bolts that holding the bearing block and tighten back ,it was free every thime but still blocked after flight.

Hope my problem is gone now, I am waiting from good weader.
