Sorry Big Jim-That is not a wrench for Niedecken stems or seats. I'm not looking for an argument, I'm only trying to help out a fellow plumber. It is much better to have the work repairing 47 valves and retain a customer than to lose a (potential) customer because you only want to replace the valves at considerably more expense and disruption.
By the way, the pictured valve has built in stops so repairs can be easily done with out shutting down the whole wing (if the stops hold!)
i will try to get pictures of the wrenches posted over the week end.

Reason: correct spelling and add content
Okie Bill- I don't know where you are ordering from, but the parts should cost less than $ 100.00 plus the wrenches which are a one time purchase. I don't know where you got the above prices and item numbers, but they are incorrect. What city are you in, don't they have any parts suppliers? Hodes has some of this stuff as does other parts specialty houses.
The Washer, Seat, Gasket, and packing are #30090 @ about $20.00
The Yoke assembly is #30093 ( for shower) @ about $ 60.00
Combining these two packages gives enough of a rebuild for most valves,and you will have some washers and gaskets left over.
You may get a discount from these prices. I don't know the wrench part # but will try to find out.
Okie Bill-Now we're on the right track!
Big Jim's info is right on except that we have never found rebuilding Niedeckens to be a problem,BUT, that could depend on the water in your,or Big Jim's, area. Here, near Detroit, we have good soft, lake water that does not play havoc with the plumbing brass. A Niedecken repair does not take an hour, at least around here.
I went through our Niedecken repair kit today and here are the correct parts numbers:
30090-Repair Kit( Gaskets,stem packing,washers, seats, seat washers made of copper)
30092 (or 22213)-Yoke assembly for bathtub
30094 (or 22209) yoke assembly for shower
22909-Short spindle(actually it is a stem)
The seat wrench is 11/16, but as Jim said it is thin walled, although some standard long sockets will work. If you buy Kohler parts there is an instruction sheet inside that has good hints on disassembly and reassembly.
The "special" wrench is only required if it is necessary to remove the spindle nut which is located under the packing. Most of the time the stem does not need replacement and you would not need the wrench. The drawings of the wrenches posted by Big Jim look to be accurate.
If you get involved with this make certain to use plumbers grease on the stem threads and the yoke assembly as well as on the inside of the seats. New parts, greased up well work as smoothly as new.
As for these valves being a piece of junk, that is not accurate. Years ago these were a "spec" valve, specified by engineers for hospital and school jobs and around here they were used in high end homes and condos. These jobs, especially hospitals, do not specify junk.
Big Jim: Where did you find that picture of the wrenches? Do they sell the parts and wrenches?

I took a deep 11/16 socket and put it on a grinder to narrow the walls, then flatten it on the wratchet end so I could use a crescent on it. Works great! The special wrench could probably be made to but I got mine years ago and don't remember where from. I only had a problem rebuilding these the first couple times, cause they were a little intimidating at first. Kinda like a Leonard valve.
sigpic3:00, I mean 5:00, and work is done. Time to crack a cold one.
