Does anyone happen to have a spare Cremina piston rod thread cover like the type OE includes in their rebuild kit that I can buy/have/borrow? I don't need the rebuild kit, but I do need a new upper group gasket (which I can get,) and the thread cover. I'm sure you all can guess why I need only these 2 parts :).

To clarify, I am looking for the little thread cap that OE sells with the rebuild kit so the piston rod threads don't rip up the upper group seal.

Thanks!

Find a thin tube or several wraps of masking tape.

Check this post out: DIY-Olympia Cremina piston rod seal "tool" and Fix
Wrapping the end of the piston rod with tape doesn't work. You'll end up damaging the seal and leaving small bits of tape in the group. Don't ask me how I know :roll:

If you aren't able to find/make a suitable tip, let me know and I'll see what I can do.

EDIT: Just saw that you have a 2002 Cremina. If that's the case, the shoulders of the piston rod should be smooth and the rod cover is unnecessary. The old style rods need the cover as the edges have no slope, the newer ones just need lube and they're good to go.
