Rated 5 out of 5Â by Tekno1 Replaced worn out original and works as original :)
There is no instructions on the package so following could help DIY people:
When I disassembled the old gasket, which came with new toilet so it was factory assembled, I saw some sort of hardened silicon glue residue on the toilet tank where gasket came out. I had to scrap using utility knife and clean the hardened glue residue. Taking a hint from my observation I put silicon glue between gasket and toilet tank. There is no leak and works well on my two toilets those are KOHLER Ricardo Light brand. To disassemble one need to twist lightly black flush tube assembly about 20 degree clockwise to remove the tube and seal assembly. After put the seal on, lubricate the bottom with some jelly and push down, rotate counter-clock to reseat the assembly. Do not apply to much force since assembly has small plastic extensions to lock in and those can break easily (but push down the assembly firmly to engage the plastic extensions under the tank).
Since you are changing gasket most likely flappers also needs replacement. Many years I changed flappers I bought from local shops and non worked without some leak but I found Korky 2010BP Float Flapper For Kohler Toilet Repairs FITS VERY WELL and no leaks (This is a OEM replacement for KOHLER 83064 FLUSH VALVE REPLACEMENT FLAPPER). I guess original is a better choice but the original flapper is not available locally.

Rated 1 out of 5Â by Jim2014 Not up to Kohler standard
I don't know if this was a genuine Kohler part, but it was way too squishy. So it doesn't make a seal between the toilet and the flush valve. So it leaks and doesn't work. Kohler is sending me a new one, free. If possible will update this review to indicate whether the problem is Kohler part or HD supplier.
