Clutch adjustment on a newly installed Exedy?

Hi all - I recently had an Exedy Mach 500 clutch and flywheel installed, which now has a bit over 500 miles on it. Initially the engagement point was pretty close to the floor. Now its quite a bit higher; almost at the top of the pedal travel. Is there a way to adjust to get it back closer to the floor?

No. Your car has a Hydraulic system. I would go back over everything. Make sure the clutch Master is working properly long with the Slave Cylinder. I would not suggest to continue driving the car like this until you get it situated. Tis will cause your clutch to burn up prematurely!

Thanks for the quick response

wouldn't it be the opposite? the closer to the floor engagement is the more likely its rubbing while disengaged? Keep in mind I don't know too much on clutches or transmissions.

I have seen it work either way. With the pedal having to come up further, it seems there is not enough Hydraulic Pressure.

aah, That makes sense.

Have you tried to bleed the system since this happened? Was the slave cylinder replaced as well? Jack up the driverside and slowly pump the clutch, see if that helps.

Make sure clutch was blead properly......

My understanding is that these are self bleeding systems. At least my year.

Easy way to tell. Hard to see but look under the car on the top drivers side of the transmission/bellhousing just above where the line goes to the slave cylinder. Is there a bleeder screw?

A low pedal engagement point most likely means it needs to be bled. A higher pedal would indicate that it has all the air out of the system. They are all self bleeding, including the early lines with the bleeder. It's possible that your system wasn't bled all the way after the clutch install. As you used it, it bled the system out more, hence why the engagement point moved up the pedal. It takes ALOT of pumps of the pedal to get all the air out. Even if you use the vacuum bleeder method. I never found raising the front left of the car to help at all. Pretty sure that's just an "internet trick". When the slave is replaced, if it was not bled before installing, it takes much longer to bleed the system. Also, as the clutch disc wears, the pressure plate moves closer to the flywheel, which causes the diaphragm fingers to move closer to the slave cylinder. This will also make the engagement point move up the clutch pedal.

so would he now need to remove shims under the slave to move it a little further away from the fingers? Sounds like it is disengaging the pressure plate very soon into the pedal travel, which seems like it would end up pushing too far in on the fingers at full extension of the slave?

Thanks all for the insight

i had this clutch and peddle height is high. also these have a stiff p/p. i'd say if you want it lower to ad a shim between p/p and flywheel

When I installed my Spec 3+ it also engaged closer to the floor but now it is near the top and has stayed that way. 30k miles later and still no problem.

Good to know

Also have the Excedy 500 and it engages at the near top. No issues. Love it!
