What is the part # for the special tool / wrench needed to replace the Kohler GP1059291 Seal for All Single Flush Class 5 & Class 6 Canister Toilets?

This question is for the older style 2 piece Kohler toilets (model 4634-AA) with the 3 and 1/4" flapper valve. Notice the extra large nut holding the assembly onto the tank. It's obvious that in order to remove the seal inside the toilet, the entire flush assembly around the flush hole must be removed. That means loosening the extra large nut holding it on from the bottom. But I can't find the part # of the specail tool / wrench needed. What is it?

The attached picture shows the bottom of the tank and me trying to replace the wrong part only to realize the part I got was small enough to fit inside the flush hole. This model has a 3.25" flapper valve, not a 2" flapper valve. Getting off the extra large nut is the main problem and needs a special tool or wrench.

Answer: 
No tools were needed.. shut of the water hold the handle up and you can get to the seal at the bottom of the canister. My old one got sticky and was hard to flush. There is a little plastic that you twist to release the canister. Check the web site for a directional video..

Answer: 
You're right, you don't need a special tool but you're wrong that you can reach in and turn the assembly with the overflow tube on it. The entire assembly is held in place by a large plastic nut under the tank, see pictures. But I am not about to buy a wrench that can turn a nut over 4 inches in diameter.

Answer: 
Thank you for your inquiry. I apologize but there is no special tool/wrench needed to replace th GP1059291. What you need to do is take the piece that the rim feed hose goes through the middle of and turn it counter clockwise and it will unlock; pull out that piece and then the outside shell that the gasket is attached to will come out; lastly take the old seal off and put the new seal on.

Turn off the water supply to the toilet.
Pull out the soft rubber tube that connects to the top of the filler column in the center of the tank.
While gently twisting, pull out the big tube in the center of the tank. It has a T shaped catch at the bottom that will pull out. Don't work too fast, be patient and it pulls out. It'll flush when you pull it out.

Turn off the water supply to the toilet.
Pull out the soft rubber tube that connects to the top of the filler column in the center of the tank.
While gently twisting, pull out the big tube in the center of the tank. It has a T shaped catch at the bottom that will pull out. Don't work too fast, be patient and it pulls out. It'll flush when you pull it out.
The rubber ring at the bottom diameter just pulls out of the end of the big tube you just removed. there's no glue or fasteners, it's just resting in a groove.
put in the new ring.
push the big tube back down (now that it's out you can see the T at the bottom of the tube and if you look into the tank you can see where it fits into. it's obvious once it's apart.
look to see that the new ring is concentric in it's seating.
turn the water back on.
if it still leaks after you replaced it, repeat these steps making sure to properly load the rubber ring into it's seat.

Customer Reviews

Rated 4.5 out of 5 by 93 reviewers.
Rated 4.0 out of 5.0 by Stopped my running toilet 2 minute install. Fixed a running toilet. Hopefully will last longer than the old red version. July 5, 2016
Rated 3.0 out of 5.0 by CRAZY expensive for a rubber o-ring, but you have no choice If you have a leaking Kohler canister style toilet valve you WILL eventually need to buy multiple of these. It's insane that a 4" rubber o-ring would cost $7, but you really have no choice. June 28, 2016
Rated 5.0 out of 5.0 by Perfect replacement The installation video on Home Depot for this item was far better than any video found on the Kohler site. It made installation very easy and fast. My leak has now been stopped. June 24, 2016
Rated 5.0 out of 5.0 by Did the job Easy to install. I shouldn't have waited so long..... July 5, 2016
Rated 3.0 out of 5.0 by Okay I'll admit I haven't installed the gasket yet, but hey, it's a gasket. It came without instructions, so I'll have to find instructions for taking apart the toilet innards on Kohler's web site. For this reason I've rated the ease of installation as poor. Assuming it does the job, it's considerably cheaper than buying a complete new part. It's a Kohler-branded part, so I have some assurance that it will be appropriate for the application. Quality is average because there's nothing that stands out about it. The package had clearly been opened previously. It was also covered with the dust of the ages, as if it had been in storage for years. I don't know if it was purchased, opened, and then returned as incorrect for the purchaser's application, or opened in the store for some reason. Home Depot's practice of reselling open returned items at full price without any indication as to why they were returned is off-putting. In the past I've bought items that appeared unopened, only to find parts missing and/or broken. Hence, the value is average. If it had been an absolutely new, unopened package for the same price, I'd have rated the value higher. Finally, the pick-up process is incredibly annoying. It should be enough for anyone, me or my designated agent, to present the notification email. We should not also have to produce ID, and I should not have to explicitly change the approved pick-up person from myself to someone else for a $7 item. I understand not handing out multi-hundred dollar items to just anyone, but there should be some cost limit below which the email is sufficient. July 5, 2016
Rated 5.0 out of 5.0 by Works well Good fit, easy install. Hopefully it lasts longer than the original June 14, 2016
Rated 2.0 out of 5.0 by Works ok, but pricey. Original oem gasket/seal lasted less than 3 yrs. This replacement did the trick, but $7+ for a 20 cent part is pricey. Replacement is easy, but not intuitive. The flushing cylinder slides up/down on a post, which is mounted through a key hole slot. Remove by twisting 1/4 turn counterclockwise. Contrary to the YouTube videos, don't twist the top of the post, which will break. Instead, lift the flushing cylinder and twist at the base of the post. June 7, 2016
