KOHLER471147 Genuine Part Flush Valve Assembly Kit, 0.75 x 3.25 x 10.00 inches

Instructions to recommend wetting the o-ring gasket and I soaked it underwater for 10 or so mins as another reviewer recommended. That certainly helps but it does indeed still take significant pulling force towards the “front” wall to get the three plastic teeth seated deep enough to allow then turning it into place. The three plastic teeth are fairly robust but it is a bit of an anxious moment when pulling hard and turning the smaller plastic bits into place against the unforgiving porcelain. I found it helpful to (without the seal) mark in pencil on the “back” wall the exact angle position of the piece where the three teeth perfectly align with the three areas that accommodate the teeth, so I knew it was in the best position when pulling hard with the gasket on. Can see why the clamp squish and freeze method would be helpful to eliminate the need to pull hard while installing. Works well when installed. OEM kohler box and parts.Good that Kohler moved away from using this part in subsequent models. It’s a relatively unique plastic part not available in local hardware stores and when your old part breaks (the plastic teeth on my 23 year old original part broke while I was trying to replace the flapper) you want the most essential parts of your toilet that occasionally need replacing to be parts that are available ASAP in local stores.

Quick install (no problems):- Turn off the water supply to the toilet.- Drain the water from the tank by flushing the toilet and soaking up any remaining water with a sponge or towel.- Make sure you have good lighting and visibility inside the tank for easy access.- Remove the old flush valve by twisting it to the right and pulling it out of place.- Install the new flush valve by aligning the three teeth on the valve with the notches inside the tank.- Use both hands to press down firmly, then twist the valve to the left to secure it in place.- Turn the water supply back on and check for leaks.The entire process should take around 20 minutes.

Serves the purpose

Soak the ring for at least 30mins in water. Wear some mechanic gloves with some grip to hep secure the item in your hand and protect your skin from the sharp edges on the rear. its not easy, but with patience and muscle you'll get it done.

I installed this in about 10 minutes, which included the time it took to drain the toilet tank and remove the old part. The only hard part is that you are pushing the part and the gasket into the wall of the toilet tank where the hole is and then trying to twist it into place. So basically you are really using force to push it into the front tank wall as hard as you can as you twist it into the lock position. Grease the wall and the front face of the gasket with silicone if you need to and it is very, very easy to do and you won’t risk damaging the gasket. I am north of 50 years old and I did not have a problem at all.This was a direct OEM replacement for a Kohler 3386 flush valve. It includes the seal/gasket, along with the new Kohler flapper and the black pipe pictured. To remove the old part you push it toward the front tank wall, while sitting on the toilet backwards with the lid down (you are pulling it towards yourself). As you are pushing it against the tank wall, just turn it from 12 o’clock down to about 2 o’clock and it will release. The installation of the new part is basically the reverse. Align it toward 2 o’clock, pull it towards the front tank wall to compress the gasket into the wall of the tank and turn it up toward 12 o’clock. I did not do any special prep, other than coating the toilet wall along which you were spinning the part with silicone. It is best not to use Vaseline or any petroleum based products on the rubber gasket, as it will deteriorate it. Use silicon lubricant instead if you need it.Amazon sells just the seal separately and I would have saved money just buying that. For reference, it is part number 84676. If you need a new flapper, which is about 6 to 8 dollars, you may as well just buy this because you get a new black tube for about two dollars and that way if you break a tab trying to install it you still have your old one.

Genuine Kohler part. Half the at Amazon compared to from Kohler. The old ones gasket disintegrated and the toilet was always running. Looked simple to replace BUT I did not read the reviews and it would take Hercules to compress the gasket and twist and lock it into the hole in the ceramic. I tried everything, soap to lube it but no dice. Then I found a video from an old guy who said to place the gasket between 2 pieces of wood clamp it so it is compressed and flat and then freeze it. I decided to go to Amazon and read the reviews. Many reviewers mentioned this old guys and the trick to freeze the gasket. I got 2 pieces of wood put them on the gasket and clamped it down to where it was no more than quarter inch thick. I put it in the freezer for 4 hours. With fingers crossed I took it out slipped it on the valve and inserted and twist it with no effort into the ceramic hole!!! Unbelievably easy!!! Exactly like the other reviewers said!!! A big shout out to them and their reviews!!

Perfect fit, while I was looking up to verify if this was the right version for my toilet, I came across a tip on how to install it so easily. Squeeze the rubber flange between 2 small pieces of wood and then freeze overnight. You have about 5 minutes when you take it out that it stays compressed and then the whole assembly fits right on. I have had to replace a different toilet a while ago before I knew this and it was the most frustrating thing ever, trying to turn the assembly on while compressing the flange at the weird angle.
