I'm in need of help. The lens was improperly installed (not aligned to infinity) and now is stuck. Is there a way to remove this on my own? If not, any recommendations for a repair store in US, preferrably in West Coast (I'm in SF Bay Area)? The body needs adjustment anyway since some shutter speeds are off and the film counter is not engaging properly.

Thanks in advance.

if i remember correctly, you need to remover the 3 screws close to the lens mount,( not sure if you need to remove any of the screws underneath the chrome ring), the ring cannot removed so you have to so you have to twist it and press on the lens lock, then it can be removed it takes a little bit to do it, it has been a while since i had to do it, Jim

Thanks for the info, Jim. I'll give that a try if not I'll just send it to Stephen Gandy for repair. Got a quote for him with the CLA already, basically CLA cost+$75. If I can remove the lens I'll just send the body in for CLA.
 
Set the camera body internal focusing helical to infinity by using the camera focusing wheel, then gently turn the lens focusing ring to infinity until it clicks, and it's solved.

I tried that but the focusing wheel would't budge. I also tried to remove the 3 screws on the mount but that didn't work either. So it's off to Stephen Gandy after the holidays. I'll wait for the holiday rush to avoid having the camera mishandled by the overworked couriers.

The coupling flanges of the lens spring coupler and the camera body internal helicoid are made so that you cannot force the mount with the lens left into an improper position (one flange is larger than the other two) so, chances are, that the lens coupler hasn't engaged into the camera helical.

When you think of it, you realize that even if you mount the lens on the camera with the lens not set at infinity, you just cannot jam anything, you just have to rotate the lens focusing ring towards infinity after having mounted the lens on the camera external bayonet.

So I still can't get why you cannot sort it out. I had a 35/2.5 on which the spring coupler was too weak and so it was keeping disengaging from the camera helicoid at some focusing point (now fixed), but nothing got stuck, ever.

I was thinking of that as well but I can't figure why it's stuck right now. I don't want to force anything at the risk of damaging the lens or part of the focusing mechanism.
 
Try using just a little more force than you've tried to this point. But not enough to break anything.
 
Highway 61,
This definitely can happen. I think you end up locking the infinty-focused lens onto the mount with the internal mount so far extended that nothing moves.

I think I ended up using a heavy set of pliars when it happened to me about 15 years ago, but both the lens and the camera we heavy used and reasonably expendible (and there was no RFF to rended assistance).

try setting the shutter on the camera to T, wind and open the shutter, take something (like a bic pen cap or a small paint brush handle) and push the cam, should move about 1/8 of an inch, them focus the lens at the close focus, move the focus wheel to the lock position, then try to see if the lens will loosen up.
