shower valve stem repair challenge
2 Attachment(s)
I am attempting to replace the valve stem/seats for a Kohler 3 faucet tub/shower. The outer covering over the cold faucet stem is stuck. In the old stem that is getting replaced, this cover is metal.(The new ones are plastic as seen on the hot faucet stem already replaced) I have tapped it with a hammer repeatedly, used a vice grip-which is just tearing apart the metal, i've tried heating it with a's not budging, just tearing off metal pieces.

Any suggestions would be greatly appreciated

A plumbing socket wrench doesn't get a grip on the valve nut. On the hot water stem, that I already fixed, I had to use a deep socket which still meant hacking off part of the valve stem to reach it.

Is there a little horseshoe retaining clip that's still in there by any chance?

Try soaking stem nut in penetrating oil like liquid wrench or pb blaster overnight. It looks like you got that stem nut worned down to a nub, doubt if you can get a socket over it now.

You may have to dremmel or cut it out like you did the hot water one. Some can be a real pain to get out. Anyway you could just cut off stem nut without destroying tile or valve stem so you can get a deep well socket on it?

Be sure the valve is in the "on" position. If it is turned off, the washer being pressed against the stem can make things bind up.

Lime Away will be more effective than penetrating oil.

Thanks everyone. Ended up just taking the dremmel to it
