american-standardfaucet
I can’t for the life of me find any screw or cap on this thing. It has been leaking like crazy and I need to check and/or replace cartridge.
It is an American Standard, that’s all I know. Probably about ten years old. Can’t figure out the model or find the literature from purchase.
Any help? Please?
The next step secret to getting more of this faucet apart are the two slots cut across the cupped part. See the arrows in the following picture.
It looks to me as that the cupped part is threaded down inside the larger diameter part that sticks up from the hole in the sink. There is probably a special tool used to engage these slots to thread the part out. It may be possible to lay a piece of metal bar stock across these slots as a tool. If you do that make sure that it has nice square corners.
Unscrew the cap and pull off the brass collar that will reveal the plastic grey temp handle. Then there is a green clip that is split. Pull the green clip out and the remaining handle components will come off. I think it’s component number 1.4 in the parts breakdown.
Visit the grohe website for that trim and it’s really obvious and easy to get it apart.
Good luck!

Modern American Standard 4" center-set lav faucets with lever style handle typically have a set-screw at the base of each lever in the back. It may be difficult to see the small screw hole as there is usually a little cover plug that needs to be pried out with a small screwdriver or similar tool. You will need a hex wrench:
Another style (less common in my experience) simply requires a firm pull upwards for handle removal:
