You should be able to remove the tank lid, reach into the cistern and find submerged at the bottom towards the front of the toilet the plastic wing nuts, hold onto these while tightening the plastic bolt from the top.

I have a Kohler toilet with a similar design, not sure if it is this exact model but they look very similar so I hope this works for you.

Cut it out David with a flat bladed hack saw with as many teeth as possible. Give it a shot, pays to buy the best HUH????

Kohler will try to sell you $46 anchor bolt kit 84999 & also there special tool. You should expect that for a $400 toilet.

Try this instead:
1. Use 1/8" drill bit and drill and drill around the bolt until the anchor material can be removed.
2. Carefully clean hole with 11/32 drill to remove all remaining acchor material.
3. Go local hardware store & buy a 10 - 32 3/8"X3/4" rubber expansion plug (make certain threaded part is brass & has shoulder on 1 end), a 10 - 32X1.5" Phillips bolt and couple of small fender washers fit the seat.(about $4 for 2)
4. Assemble carefully not to over tighten and crack the porcelain.

Hope it helps

I repaied one of these laast week and it had the Plastic nuts in between the webbing on the seat where the lid connects I believe You remove the plastic cap with a knife and use a flat tip screw driver to remove the screws and replace the seat.

Enlargeing the holes will not turn out well.

Modify the seat to take the plastic bolts.


Hope this tip helps.

There is clips where the bolts should be .Flip the clips up grab hold of the seat and pull it strait out towards the front of the toilet.

Give Kohler a call AFTER you read the instructions thoroughly. Good Luck, seriously.

if so cut 1/4 inch off the bottom of round part of flat valve
