Couldn't find my problem with a search....
I have a Kohler K-T14420 Shower control whose stem extension is very loose. I think a retaining screw may have broken off (I have a parts diagram). My problem is that I can't remove the set screw from the handle stem despite repeated applications of WD-40. I apply a fair amount of force, enough to deflect the 2" hex tool a half inch at the end but I'm afraid of breaking it off inside the screw. Part of the problem is that when the shower is off, the screw points down, so WD-40 doesn't really soak in. (When the shower is on full, the screw is horizontal, and I'm quite wet since there's no shower shut off)
I considered heat, but since the exterior is chrome, I couldn't see applying my torch to the handle. If heat is the answer, how do I apply it without ruining the finish?
If heat is not the answer, what is? As a last resort, I think I can drill out the set screw. I'm not too worried about having to replace the handle stem and stem extension. Is this the best way to go? What a pain.
