Hello I'm Mike. I'll be glad to help you with this issue.
Since this is a one piece toilet they made a push in insert that the bolt screws into
Poor design on their part
If the bolts will not unscrew you will have to cut the head off of the bolt, and let the insert fall inside. Then you will have to get a new kit from Kohler to install a new seat
Really? The replacement part has a weird-looking nut thing (it looks a little like a butterfly nut). I would also think that, if there's a threaded insert, the screw should unscrew pretty easily.
The insert must be turning inside the hole. Do you have the model number for you toilet. It should be inside the tank, or under the lid
Sure: it's K3386D
give me just a second to look up your exact model
great--appreciate your help. this is seriously lame on their part
From what I'm seeing it looks like there are two inserts that go into the bowl that the bolts will screw down into
Part number 84999
Hmmm...that's not what's in the replacement pack in the toilet seat. Do i now have to call Kohler to get that, too?
Take a look at the pdf. file above and see if that's the same model you have
yup--that looks like it. but look on the next page. see where they show the hardware for seat installation for the K-3386 (for the K-4463 toilet seat)? that's what's in the package with the new toilet seat--nuts, not inserts. You think I have to call Kohler to order them separately? If so, what's with the nuts?
Those nuts are what comes standard with all toilet seats. They will only work with a standard two piece toilet that you have access to the bottom of though
All the Kohler one piece toilets I've ever worked on require a push in insert for the seats. Because you have no access to the underside to install the nuts
that makes sense. i guess i gotta call kohler tomorrow. idiots. btw, my hacksaw won't fit in that tiny space--I guess I also gotta buy a special hacksaw, too, huh?
Do you have a dremel tool?
oh, yeah--that's a great idea. thanks very much--i think you nailed it. now to flame kohler on amazon for this...
Go get em!
hey, thanks, mike! this is a great service--glad i found it. take care!
They make a great product, but some of their engineering is questionable
