Has anybody tried adjusting the clutch by changing the free play?

I know, the clutch is self adjusting. Well I still don’t like it that it releases so high. Has anybody tried increasing the free play (SM 12-4) to make the release point lower?

the reason it releases so high is because your clutch is almost worn. Adjusting the free play will not fix your problem. The solution would be replace it with a new clutch.

but thats just my opinion.
 
I think this is more a function of the individual clutch. My ACT clutch releases much closer to the floor than my OEM clutch.

My new OEM did not really change the release point vs. the old worn out one.

Bob, try emailing Chris at SOS. I know he has some experience playing with the settings, but again I think it has more to do with the clutch end than the pedal end.

I would love to shorten the entire throw for the track car so I can do left foot braking more easily. Maybe someone will chime in on this one.

Not so ...... this is a typical signature of the early model clutch release - mine has been this way for the last 12K miles I've owned it (26K miles total) and others I've driven have been similar.
 
You can change the pedal height by loosening the jam nut behind the pedal at the clutch master. Turn the push rod (with your fingers) to your desired length, a turn makes a big difference. Tighten and test. Usually takes several cycles to get it right.

Yes, looking at the schematic, this is what I thought. It seems that you would need to shorten the pushrod (screw it into the clutch pedal further) to make the release point lower. Is this correct?
 
Hi Bob,

Yes that is the correct way, but I do agree they just grab high:). Mine has been that way for 20K miles.

HTH,

Did "search" on clutch adj, and found this in archive. Didn't want to dup.

Man, I'm glad someone clarified that answer. I was getting worried that my
clutch was going. I thought it was just my car.

Mine also releases high, even when new it releases high. Some signs of wear are clutch chatter prior to slipping but may also be caused by oil or dust. At least that was the case with my old 911.
 
Since this thread has been resuscitated, I will follow up with what I tried in 2004. It is indeed possible to adjust the engagement height by changing the pushrod length, unfortunately on my 91 NSX back then, it was already adjusted to full position the one direction. The engagement height is certainly not necessarily a function of clutch life.

Hi Bob! How's the Zanardi and spec racers coming along? Don't think I had the chance before, but thank you for letting me come over and check out your 91 when it was for sale. Saddly I didn't have the extra cash to afford your mint 91 but I did manage to get myself the nsx I have now :) Hope all is well for you and the Mrs in colorado. For the record, your 91 is the first NSX I've ever touched, heard, smelled and sat in :)
 
if your clutch was grabbing low, now after 2-3 years its grabbing high, then its clutch wear.

if you put in a new clutch and it still grabs high, then its clutch adjustment.

usually when the clutch is grabbing at the top, then its clutch getting close to time to replacement, but some people like it at the top so they adjust it that way.:smile:
