Kurbelwelle Simmerring, presumably...
Yes, if you google for 'Porsche' and 'KWS' you find 100'000 hits to the 'Porsche drama'.
:D
Well, I found out I should have written it as a single compound word, too! Kruckstockschaltungsgestange is one of my favourites.
There's an awful lot of occurrences for something that's supposed to affect only a small percentage of engines - guess they must'e made millions of engines, then.
It's a widespread Porsche problem which dates back to the 996 AFAIK. But <=993 were far from being dry under the engine. German quality... My wild guess is that they shaved off 1 Cent of production costs and ended up like VW with their timing chain drama.
I didn't have a tool to install the 'KWS' on mine but I took special care of it. I've mounted the flywheel today, Loctite blue, 105 Nm, several steps in a crisscross patern, 20 Nm, 50 Nm, 80 Nm, 105 Nm. Old one: 0.03 mm runout, new one 0.04 mm runout. Tolerance for new one: 0.05 max. All fine then.
The intermediate shaft failure was even worse - simply down to very poor bearing design.
The parts have finally arrived at the dealer in Japan, faster than expected. Next week, I should be able to continue the tasks...
Diff with the NSX-R plate, very slight difference between the two.
Attachment 12818
Mounting it:

Honda tools rule!
Attachment 12820
The diff is now at 170-180 Nm instead of 88 Nm.
Mainshaft. Something is fishy with the 5th gear, wear and rust. Everything has been changed: 5th, hub/sleeve, collar, needle bearings, ball bearings.

Working on the rest tomorrow: shift forks, intermediate axle (new bearing, new seals).
