I DON'T THINK THEY CAN BE ADJUSTED,BECAUSE IT OPERATE ON FLUID. MY EXPERIENCE WITH THIS PROBLEM RESULTED IN CHANGING OF THE CLUTCH SLAVE AND IT SOLVED THE PROBLEM. OF COURSE THIS WAS A DIFFERENT BRAND OF CAR.
there is really no adjustment that can be made, because it is a hydraulic system, the only thing that can be done is to have a new clutch installed.
If it is hydraulic, there is no adjustment, just make sure no air is in the line. If it is cable, then there should be a screw at the clutch lever which will tighten the cable. If the clutch really slips, then, well, plates will have to be replaced.
no not really , but you can bleed air from it by the same method of bleeding brokes
There is really good information on the hydraulic cylinder at http://en.wikipedia.org/wiki/Hydraulic_cylinder. I do not believe a Honda Civic comes equipped with a Hydraulic Cylinder. It does, however come with brake and clutch master cylinders. If you are having trouble with your master cylinders, you need to get your brake lines and brakes checked as soon as possible.
If it is a hydraulic cluth then there isn't really an adjustment. If it's mechanical then just loosen the bolt/nut on the fork on the rod going to the transmission.
Sounds to me that you may have a clutch problem. Check the level of hydraulic fluid in the reservoir for the clutch under the hood. If it's low or empty you have a leak at the clutch master or the clutch slave cylinder. Filling it up may make it operate again but only until it leaks out again. If the reservoir was full you may need clutch replacement.
You really can't adjust it unless you have the transmission separate from the engine and you can get to the clutch.The clutch in the Miata is Hydraulic so if you having problems with you clutch most likely the problem is the master cylinder, slave cylinder, or you clutch is bad.Correction 10/26/09:The above is partly incorrect. While it is a hydraulic clutch, there is a mechanical adjustment at the clutch pedal itself, which allows you to adjust pedal height and freeplay. Contorting yourself to look up under the dash to see near the top of the pedal, you can see the stop/switch that prevents the pedal from rising any further from the floorboard. That can be adjusted by disconnecting the wires, loosening the locknut, and turning the stop/switch to the desired pedal height. Freeplay (the amount of pedal movement before feeling clutch resistance) is adjusted by loosening the locknut on the rod connected to the clutch pedal and going into the firewall. Turning the rod one way or the other will increase or decrease freeplay. If you are adjusting both, always adjust pedal height before freeplay, as pedal height affects freeplay.Now, clutches in Miatas rarely require adjustment, and most cases where one seeks to solve a clutch that isn't fully disengaging, will find that the slave cylinder (on the transmission bell housing) is going bad. (common at 100K miles) The good news is it's fairly easy to replace. You just have to be careful to properly torque the mounting bolts. (easy to strip the aluminum threads, as it only requires 12 to 16 ft.lbs)
There is no adjustment on a master/slave hydraulic clutch system. It is self adjusting every time you release the pedal, the hydraulic fluid is released back into the reservoir and pressured equalize, just like the brakes. However you can diagnose problems usually quite easily based on the symptoms. If the clutch pedal will not disengage the clutch, then the master or slave cylinders are bad. It could also be caused by low clutch hydraulic fluid, but the system does not consume fluid so if it is low then there is a leak, usually at the master or slave cylinders, so we are back to the first answer again. If the clutch will disengage but will not engage properly, (slipping) then the clutch disc is worn out. If you have to pump the pedal several times for it to work then their is likely air in the system that needs to be bled out, but this condition would lead to the next logical question, "how did air get in the system"? and would have to be answered, and would probably be due to low fluid, due to a leak, due to a bad master or slave. SO, you really have two choices. A bad master or slave or a worn out disc depending on if it wont engage or wont disengage. Forget about adjusting it because you can't!
anytime you press in the clutch on any car and you hear a noise its likely to be the throw out bearing. on a mechanical clutch there are alot of cables and pivots that can make noise as well. on a hydraulic clutch its really just fluid and a few moving parts (inerts of the master cylinder and slave cylinder) the rest are really in the clutch housing itself. it could also be something as simple as a loose bolt from somewhere or as bad as a loose flywheel. either way clutch systems in general are pretty simple and it can only be a few things. best bet is check the throw out bearing.
This is the clutch slipping and you need to adjust your clutch pedal!!!! Soon very Soon!!!! If you don't say good bye to your new clutch....We need about an inch of play in our pedals... before the clutch engages... My 3 did the same thing and the clutch was really firm...I just installed new clutch and flywheel etc... It was fine and the I had to adjust the pedal because it the nut was loose and the pedal stuck to the floor ... I had all fluids and no leak so it had to be the pedal.... I adjusted it to be all the way to one spectrum where you barely touch it and it changes gear... so i made it a little less firm and then a little less firm and it was fine after that....Driving it hard or just put-zing around .... Haven't had problem since..... google it and you'll find out how to adjust the pedal... This answer is granted only if everything was installed correctly....
This team really pulls together in the clutch.
im thinking you need a new clutch.
