Ferrari Scuderia Chrono Pushers

Does anyone know how the pushers are attached to the case on the ferrari? I bought one that was "stuck" and the pusher fell out one day. I just found a piece that looks like a spring that I do not know if it belongs. Other than this, Is there a source for replacements? Want to fix the rep as it is beautiful otherwise. If I cant, I'll offload this for parts and pick up another....

Any help is appreciated...

That happened to me too. One day the pusher fell out and all I was left with was a spring. The pusher is screwed in so if it gets unscrewed, you're screwed! :D I had no luck in getting it fixed and ended up selling it for parts. Good luck!

Thanks. I guess I could glue it in. Were you able to get parts or no?

The end of the pusher inside the case is in fact a screw head, so you can strip the pusher assembly by undoing that from inside.

The reason for the "stuck pusher" problem that these have is the pusher shaft is left with burrs on the end during manufacture, this prevents the pusher head from screwing down fully. The extra length then allows the outside part of the pusher to come off the splines it slides on and sit over them. If the whole outside pusher (inner and outer lockring) can continually rotate then you have this problem.

If the burrs are removed and sometimes the shaft shortened slightly the outer pusher stays on the splines. You also need to loctite the thread to prevent it coming apart and parts getting lost.

Thanx for the excellent explanation.

Everything you said makes sense. Unfortunately, the previous owner screwed up the actual pusher part so I need the entire subassembly I believe. I could not get the sliding part to slide any more and snapped the screw off trying to fix...

Know where to get replacements?
