Have you removed the #75130 nut?
I'm having trouble removing the cartridge from my Kohler 168 kitchen faucet, single lever. Any suggestions?
I'm trying to get that nut but everything underneath is turning..can't hold it.
Try getting it into proper orientation again, tighten the #33832 nut or, the screws on the #78539 nut. Hopefully you can get it to stop spinning and get the nut off. Mabe you'll have to get someone down below to grab hold of the #73488 body on the exposed threaded shank to keep it from spinning. If you have to do that, I'd try leaving some good threads close to the nut so it can be spun off slightly before it locks up. This will help a lot someday when you have to change the faucet.
Suggestion: Remove that Kohler pile of junk and install a Moen.
