This came up in my search for a remedy to my problem with my A. You posted it in 07. My problem is I set my fw where it needs to be and tighten it the fw slips out and away. Your 07 reply wasI had the same problem with my 730D. I eventually drilled and tapped the center of the crank end for a fine thread 1/2" bolt and made a cup to go over the crank. I made a plate of 3/8" steel with a 9/16" hole in the center and drove the hub on with the bolt until I had the right end play. Then tighten the big square nut while the homemade press held it to spec.way. Any additional info you have on this fix is appreciated, was it a lasting solution and did it cause any issues with the bearing or crank. Do you have any photos on it? Thanks
