An Additional Volvo Steering Arm Removal Question

[Antti84]

In continuance of an older topic titled Volvo steering arm removal

I need to get the gimbal ring off because I need to sandblast and paint it. I screwed the three screws off at the bottom, bought the 9/16" bolt and a big washer according to the descriptions above. What happened to me was that I destroyed the threads on the 9/16 bolt, and it slips off. The steering arm has moved a bit however.
What am I doing wrong?Is there anything else besides the three bolts under the outdrive, which needs to be removed? Does anyhting needs to be removed from the inside?

Thanks for all help

I think that should be it.
I took mine off a year ago using that post as well, I didnt have any issues. It was tight at first, but it did pop off.
did you get the right type of thread 9/16 thread bolt?
and what grade was it? Maybe too soft?
Can you see what the threads are like on the yoke? Hopefully they are not stripped out.

when I removed mine, I also took off the swim platform. Made it easier to work on.

can you take some pics? Maybe just missing something.
