Crown and Stem

[jmt]

I've got a Rollie (rep) crown that came attached to a 2836-2 stem. But... the stem cracked (don't ask) ... so, I'd like to remove the stem fragment from the crown, but they are very tightly attached. Any tips on wrenching the two apart would be greatly appreciated!

Thanks.

The stem screws into the crown, sometimes glue is used to make a tight fit. Try to use a match or something to heat up the connection, melt the glue, and then unscrew with a pair of neddle nose. Be careful as the metal will get hot.

Thanks Drop. Forgot to add that I had already tried heating it. Hoping for any other tips, but I will go back to heating and twisting!

If the stem fragment that remained attached to the crown is long enough, heating usually works. You need to get the crown really hot.

A soldier iron is the best way to apply heat.

Heating the crown only, and keeping the stem chilly (e.g. by freezing the crown+stem ensemble before applying heat, and holding the stem with frozen pliers) may help.

Also keeping the crown+stem dipped in a debonder for a couple of days may help.

I use a gas stove. As others have stated, it gets hot and might melt the o-ring in the crown.

Thanks guys. Actually had to heat it til it turned red, but got it out. And, o-ring did not melt, so I am good to go!
