KOHLER 471147 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.

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.

After wasting several days trying to install an aftermarket generic part I realise I should only order original manufacturer parts. It took only TWO minutes. I did use a sturdy screwdriver to help push in place.

This is the apparatus that separates the toilet tank from the bowl. It fits between the two chambers and has a gasket that prevents leaks. My old unit had deterioriated to the point where it was leaking. I bought the new one here at Amazon that is Kohler replacement product. You have to insert the heat of this apparatus into a slotted holed in the bowl from inside the tank and then rotate 90 degrees to 'lock' it inplace. It's just impossible to do. Looking at U Tube instructions, I found one approach that seemed to have promise. I took big strong clips and applied one clip to each one third of the face of the gasket thereby compressing the gasket significantly. I made sure the gasket was wet and then I put the whole device in the freezer overnight. I retrieved the frozen until the next morning and was able to get it to fit into the slotted opening in the bowl and was able to turn it 90 degrees to lock it in place. The unit was not so expensive--maybe $16-18 but the problems of putting it in place were worth a lot more. I don't recommend the toilet--butif you have one then this apparatus will fix you toilet leaks between the tank and bowl.

exactly what I needed, perfect factory replacement!

This comes with a foam rubber seal which is about 1/2" thick. In order to install, the seal has to be compressed and the assembly rotated 45 degrees, which allows the 3 plastic retaining tabs to lock into place. I was unable to put enough pressure on the assembly by hand to compress the seal enough to allow the tabs to move into place. I was afraid to force it because of the possibility of breaking the plastic tabs. I solved the problem by putting the seal between two metal plates and compressing it in a vice until it was less than 1/4" thick. I let it set in the vice overnight, then put it back on the assembly where it retained its compressed state long enough to allow me to easily lock the tabs in place. After a few hours it had expanded enough to make a good seal and I turned the water back on and have had no leakage.

This is the biggest pain to install. Seems simple enough, attach one end to the inside of the tank and go merrily on your way. But no. That foam ring is so thick that you can't do it, it won't do it. There is no possible way to get it done right out of the box unless you have some special, yet to be invented tool. I saw a video where a guy got it wet, applied clamps to the ring and then put it in the freezer over night--sounds way too extreme, until you spend 2 hours trying to make it work, then you will try anything, here is anything. It comes out of the freezer thinned down enough to work and it goes on. There has got to be an easier way.

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.

This worked but it was way to hard to install. The gasket is too thick. I had to clamp the gasket between two boards and freeze it. Then I installed it while it was still frozen and squished down. It expands and seals in a few minutes.

Todo bien, le quedó perfecto

Fits perfectly and it does the job.

muy bueno

My old one lasted 25 years, but the plastic pretty much disintegrated after being underwater that long. Very thankful or the reviewer that suggested compressing and freeing the gasket to install. Made a difficult installation easy.
