The said clutch doesn't seem to be working, and I can't load a film into the camera; it doesn't pull the film around the take up spool. I think I lost a few frames at the end of the last roll, so that might be when it gave up.
This is far from being my first 35mm camera, this ain't user error. Can it be fixed?
I'm sure you know most of this, but since others may be looking over your shoulder....
The XA-2 must have good batteries to wind and fire. Turn the switch on the bottom to the "check" position and be sure your batteries are good and making good connection. If there is no beep, or if it fades away, try new silver oxide batteries. If your batteries are good but the camera still don't go beep, and your battery cover is one of those with a tiny point in the middle on the inside towards the battery, that little pip may be corroded -- scrape it gently with a knife and see if that doesn't fix the problem.
The take-up spool inside the back of the camera is supposed to slip. If it didn't, there would be more and more space between frames as more film wraps around it. What drives the film the correct amount each time the camera is wound is the sprocket along the lower film rails. Sometimes the screw that holds this sprocket in place comes out, however. If the sprocket is loose and wobbly, that may be the problem. It is possible, but really difficult to replace this screw if it's missing. The sprocket is keyed to the shaft it's attached to, and I believe the screw is reverse-thread. Good luck!
And sometimes the rewind button in the bottom comes apart. When that happens, it doesn't pop out properly to engage the sprocket with the drive mechanism. Once again, it is possible to "rebuild" this button when it comes apart, but it's much easier to just replace with another XA-2 rewind button. But you will need to get the small brass plate that's come loose from the underside of the button out from the steel post/collar in the bottom of the camera. Like the sprocket (above), it's keyed to the shaft it goes around, and you'll have to get it to line up properly to fall out. Then hold the tiny hair-like spring inside the steel collar away and gently insert the replacement button.
One other concern is to be sure the film leader is put INTO but NOT THROUGH the take-up spool. If the film is pushed all the way through the take-up spool so that it comes out the other side, it will prevent proper winding and take-up of the film.
