I'm hoping that somebody can help show me how to take apart the this shower leaky faucet (and matching bathroom sink faucets).
I didn't find any set screws but I was able to twist off the cap (counter-clockwise) but now I'm stuck. I was expecting to find a screw under the cap but instead I found this:
The bathroom faucets look the same. I think there are threads for a screw in the center, and it looks flat at the bottom. The rest of the handle is stuck pretty tight, and I've used channellocks to twist in both directions and a screwdriver to help leverage it straight off but without success.
I haven't been able to find any markings on either the shower or bathroom faucets to help me identify them. The showerhead doesn't look original (brand: Interbath) and the house was built in 2004. This sink is Kohler, toilet is American Standard, other bathrooms have Delta and a Grohe faucet so we're all over the place.
Any help to identify the faucet and/or take remove the rest of the handle would be greatly appreciated. Thank you!
Edit: I appreciate the suggestions so far!...but I'm still stuck. I pulled on the handle as hard as I could and it now have a bit of play (about 2mm). But something is stopping its removal -- almost like there's a set screw inside the handle. The inside brass gear with a hole seems to pull out with the handle (but only those 2mm). The hole seems to be flat at the bottom but seems to have screw threads inside. I've added another pic, taken at an angle. Thanks again!
