Help! Broken FA-50mm f/1.4

So I opened my camera bag today at the Angel game (damn you A's) and took out my FA-50mm f/1.4 lens, and noticed that the lens was coming out of the housing. WTF I thought to myself, how the hell...

Anyways, I got back home and took a look at it and the lens comes completely out of the zoom housing, I took it completely apart, cleaned it, made sure everything looks good internally and now, I can get it almost completely assembled except for this last couple mm's.

It just won't go in, I'm not sure if I'm supposed to screw it in, or it just snaps back in. Any help would be greatly appreciated!

That's an understatement! Can you push it back in all the way to where it clicks by any chance?

I can push it all the way back in, and it clicks, but it stop right here. The aperture works if it's zoomed all the way out, but if I zoom it in, the gap means it's too far away.

It's so close, just needs to go in that last little bit, but I don't want to force it too much =(

Damnit.

There is a guy on this forum called Eric that specializes in pentax repair if you want to ask him. I can't remember his e-mail address but if you search around here I'm sure that you could find him.

Hopefully he'll be able to help you with your lens.

Perfect, thanks!

I feel like it's something stupid I'm missing, just one little thing and it will pop back into place, I just can't figure it out. Hopefully Eric can.

Thank you!

Maybe someone that's worked on this lense can look at these and tell me if I'm missing something here...

You probably aren't missing any parts. There have been a handful of threads on this issue. As far as I can tell, glue fails on a key part, allowing the lens to unscrew. Read this thread for lots of information.

Try to use gloves next time. This is not a way to tread your baby!

Contact Eric, he is the guy.

This lens is still in production and Pentax can repair it. Do not try to use excessive force, your bill may go up.

I hope everything will be ok.

I'm afraid that not all parts are available for that lens. Pentax is either replacing with NOS or refunding. See post #20 of this thread.
