Today while changing my transmission fluid in my Evo 9, I saw that I had some minor clutch drag. I decided I'd watch Jacks Transmission How-To on adjusting the clutch pedal...

I went out and started to turn the adjusting bolt on the clutch pedal clockwise until you can no longer push in the slave cylinder (to block off the bleeder valve in the master cylinder). You then turn the bolt 1/2 turns counter clockwise just until you're able to push the slave cylinder in.

When I went to push in the slave cylinder, I saw the previous owner (just bought the car a week ago) had some kind of block and screw pushing up against the fork... The car currently has a Exedy triple disc so I'm not sure if that is supposed to be there or not...

Jack's How-To:

Did my best at night to get a photo... Why would this be here?

 

Its a clutch fork stop. Twin and triple discs are known to cause the wedge collar to become dislodged under high RPM shifting, the fork stop prevents that from happening. If you install an ACT Monoloc wedge collar in place of the OEM style, you wouldn't need the fork stop anymore.

 

Thanks!

So, how do I go about adjusting to clutch pedal to fix the slight clutch drag? Just turn the adjusting bolt, rev the car up, rinse and repeat until the car stops inching forward at high rpms?

Or should I just put the car in first gear, release the clutch slowly until it hits the friction point and make sure I am between 2.5 - 3" of distance from the floor to the pedal?

Or can I adjust the nut on the clutch fork stop? I was reading and STM said they put the bolt 1/8-1/4" away from the fork.

Thanks for the help! First time owning a pull style clutch system.

 

No problem! Yup, get all four wheels off the ground, put it in first with the clutch in and rev it to your highest shift point. Don't adjust the fork stop bolt, adjust your clutch pedal height further out inside the car until your clutch drag is gone.
