Subject: Team3S: Shootout in Dayton Update #2!

Dayton, Ohio DSM/3S Drag/Autocross Shootout Update #2:

I just got off the phone with Aaron Ruppert, (937-433-2529) who is
organizing the
DSM Shootout this year.  He is VERY supportive of us 3/S people
and cars, REALLY WANTS US THERE!  He wants this event to
be as big or bigger than previous shootouts (last year had around 280
cars,
including 4 3/S's).  He has gotten nothing but great support from the
sponsors he's contacted already, there are other DSM groups supporting
his plans and efforts.  The city hall of the track's site is going to
help
arrange better hotel deals etc etc...

So, the issue of WHEN it will be is going to be determined once
Kil-Kare dragway's administration gets back in a week or two to
hash out details/situation.  I know for a fact that there are three
3/S's in MY city/area going, I suspect the Minnesota contingent
will be there, and hopefully as the ball rolls we'll get together a
pretty good gathering of 3000GT/Stealths at this important and
fun event!

There will be drag racing AND an autocross...the dragstrip has
ON-SITE a place to do it/some sort of roadcourse deal.
I've attended the Shootout in 1997, '98 and '99 (with or without
my car!) and had the BEST time, every time.  They share our
brands-of-choice; really interesting to watch and inspect the
different cars.  There will probably be an "Other" class, allowing
13 or 12-second and BETTER "other" brands to race in a single
class to "spice it up" a little--some of us know friends who WOULD
go with us, but have a Supra (like my buddy with the 11sec/134mph car)
but don't because there are ONLY DSM's/3S's....but this would
keep out the 100million 14+ second Hondas etc.

Anyway, the DSM shootout has been in mid-July in years past;
we'll see when it ends up, but pencil in the 2-4 days required
for this, as it is a PREMIER event to be, see, bee seen at!

You don't want to have to replace your

Subject: Team3S: How to fix clutch disengagement problem?

1993 RT TT, 79K miles, replaced Getrag, clutch disk, pressure plate, and
throwout bearing 19K miles ago.

I recently have developed difficulty engaging reverse (intermittently). When
this occurs, if I shut off the engine, it will then slide into reverse
effortlessly. I also occasionally have the symptom that a few of you have
reported - a slight thud in the drivetrain when I go from neutral into first
with the clutch pedal depressed. So I suspect the clutch is not always
disengaging fully.

I adjusted the clutch pedal height and free play to specs. This improved
overall shifting smoothness slightly, but did not solve the problem. I
looked at the slave cylinder while someone pressed the pedal, and it seemed
to be extending all the way. But this is an intermittent problem, so I
replaced the slave cylinder anyway. Upon inspection, the old one seemed to
have some wear at the rubber seal around the piston, and a tiny bit of fluid
had seeped past it. I of course bled any air out of the fluid as part of the
installation.

After replacing the slave cylinder, the clutch pedal feels lighter, but the
shifting problem is a bit worse.  My dealer thinks it's a weak pressure
plate. I am wondering if it could be wear at the master cylinder. Another
mechanic suggested that if reverse is the only gear that's difficult to
engage, then it's probably internal to the Getrag, and nothing to do with
the clutch.

I think my problem is fairly common to 3S's. Before I pay for installation
of a new pressure plate, I'd like to know what you folks think. Is it worth
trying to replace the clutch master cylinder first? Has anyone done this
already, and did it help? Do you think that if the problem is only in
reverse, it's the transmission, and not the clutch? Could it be that the
flywheel is slightly warped, keeping a bit of contact with the clutch disk?

Thanks for any insight or experience you can provide.

Funny you should have this problem as I was just about to post my
own experience.  I'm not sure if you are having the same problem,
(after I re-read it maybe not) but it's so simple it's worth checking. 

Follow the intake Y-pipe down to the front turbo/intercooler hose.
right along side it is (I think) a metal vacuum line/tube.  Take a
look at the shift linkage, specifically the shift weight, and see if
it is contacting this vacuum line. 

Mine was.  AGH!  I have lived with problems getting into 2nd and
popping out of reverse ever since I bought the car.  10 minutes
after I noticed the problem, it was fixed.  You just need to
_carefully_ bend/pry/move the tube so there's clearance for the
shift weight.

I took a few pictures that show the problem in case this doesn't
make sense.  I'll try to post them in the next day or two.

Hope it's that simple for you too.

Hi Lloyd,

It has been a long time since I've seen a post by you ;) ...

Before doing anything else, try lengthening the adjustment bolt between the
clutch pedal and the clutch vacuum assist.  This should help if it doesn't solve
the problem completly.

I recently reported that the seal on my slave cylinder blew.  What was suprising
was that I replaced the slave cylinder only a year before!  Before it blew, and
since the slave cylinder was fairly new, and since my symptoms still occured, I
replaced the master cylinder.  It seemed to help for awhile but that was most
likely because the system was bled.  Replacing the master cylinder is a real
pain since you have to loosen/move the brake booster in order to get to the nuts
that attach the clutch master.

The problem is 'brake drag' in which the clutch disk does not completely
disengage.  Why it can be intermittent is still a mystery to me.  Possible
reasons are:  1) the clutch disk or the flywheel or the pressure plate are
warped and at certain times/temperatures the warping is at its worst and
dragging increases;  2) the clutch master cylinder seals 'passes' fluid, i.e. it
leaks but the system is closed so you don't see fluid loss, it just won't push
the full 'throw';  3) the vacuum assist is flakey and sometimes the 'throw'
isn't as long.  2 & 3 seem unlikely.

I have replaced both my clutch master cylinder & slave cylinder recently and I
still have intermittent problems.  I also have 65K miles on my clutch so I now
suspect reason 1 is most likely the cause.

Try the adjustment first and good luck,
Ken

Has anyone thought that maybe there is a vacuum problem? Just a thought...

I too have the same problem. I doubt very highly it is an intermittent "warping" problem, though I certainly wouldn't discount it. Another possible cause could be driveline freeplay....

Ken, I've tried it all the way out (leaving zero free play), but it didn't
help. So I brought it back in a bit to make sure that the clutch is fully
engaged when the pedal is up.

I think your analogy to brake drag is absolutely right. My understanding of
the pressure plate operation is that when the throwout bearing slides toward
the flywheel, the spring pulls back the pressure plate surface from the
clutch disk, removing its force. But it does not pull back the clutch disk
from the flywheel. I know with brakes, you still get about 15 lbs. of brake
drag even once the pistons stop exerting a force, because the pads do not
pull back from the rotor. Since it is rather easy to spin the transmission
input shaft when in neutral, it would not take much contact between the
clutch disk and the flywheel to keep the shaft turning.

I am now wondering if the problem might be related to the contact between
the clutch disk and the splines on the transmission shaft. If this area were
not perfectly clean and lubricated, wouldn't the clutch disk have a greater
tendency to "stick" or remain in contact with the flywheel? This might also
be temperature dependent - I notice the best shifting around 32 F, with
degradation above and below this temperature.

Thanks, that saves me the trouble of replacing the master cylinder. I'll
check the vacuum boost, but I think it's OK (there's a definite difference
in pedal effort before starting the engine in the morning). I have checked
the shifter linkage and there's no interference. I guess the next step for
those of us with this problem is to open up the clutch after all. Has anyone
actually solved it by changing the clutch?

Subject: Team3S: Struts/Shocks

So I've heard people saying that the stock struts/shocks won't really last
with the Ground Control kit or other higher-rate/lower springs.  As far as I
know we have 3 non-stock options that aren't crazy expensive:  Gabriel; KYB;
and GAB.  

KYB:
The general impression I've gotten is that KYBs are very similar to stock,
so I'm guessing they'd be susceptible to the same problems with aftermarket
springs/perches as the stock parts.  Is this right?

Gabriel:
I've never heard these mentioned on any of the 3S lists - anyone have any
experience/information?  They're listed on carparts.com and that's the first
I've heard of em.  They're slightly more expensive than the KYBs.

GAB:
I've heard these are the best bet if they're in your budget.  So who carries
these?  I haven't seen them listed anywhere, but heard they're pretty
expensive.

Stock:
So if you use the stock parts, are they just going to wear out
faster, or are they not going to provide adequate damping for the higher
spring-rate/shorter springs?  i.e. if I can get them discounted through
Norco or Tallahassee, would I be better off just replacing them more often
if I drop the height or get higher rate springs?


If anyone cares, the reason I'm asking is that I will need to replace my
stock (non-ECS) struts/shocks by the end of the summer (maybe sooner) and
I'm debating with what I'm going to replace them and whether I'm going to
change the springs or possibly get the GC Kit.

Thanks!
