“I find myself irresistibly attracted to cars that nobody else buys. The NSX is a classic of the genre because nobody buys it and yet it’s a fantastic car. It’s got a wonderful compactness and simplicity and unpretentiousness to it. Honda rudely continues to make them whether we like it or not, even though there can be no commercial logic in doing so — I thoroughly admire that.” Rowan Atkinson

Yes, if you google for 'Porsche' and 'KWS' you find 100'000 hits to the 'Porsche drama'.
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.
Mounting it:
Honda tools rule!
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).

Shift forks, quite easy to install.
