Output Shaft Coupling Problem

[System_Error_117]

Hey gang!

Just finished changing the output shaft seal on my A4. Now I'm trying to fit the output coupler back in place. Following Mr Moyer's video to the letter I first tried tapping it in, but with no luck, so I fashioned a press like the one Don sells. But the press has made no difference. I can slide the coupler to the point where it's just making contact with the thrust bearing, very smooth and little resistance. Key in the right position, not jammed, etc. Then I need to employ my press, which I crank on until I'm nearly bending the washers on the threaded rod, and it doesn't budge an inch. I can loosen the press and pop the coupler right off like it's made no progress at all. I'm thinking it's failing to align with the inner race of the thrust bearing for some reason. Both are clean and slightly greased. It came appart using the longer bolt method without much force. The other flange bolts are only finger tight, so if any slight play was needed to align the coupling and bearing race, it shoule be able to slip in no problem. Any suggestions? Just don't want to snap something off forcing it tighter and tighter....
