hydraulic clutch questions

can you adjust a hydro clutch? my friend has 94 mazda truck with 76k on the orig clutch. it now won't go into any gear w/o grinding. but if you turn off the engine it will go into all gears smoothly. also the clutch engages when it is only about an inch off the floor. wasn't always like that, but has been a gradual progression. i checked the fluid and it is full. so is there any adjustment, or does it just need replaced?

thanks all

Re: hydrolic clutch questions

I have a problem with my clutch also, same thing, won't hardly go into gear. My hydo clutch is working just like it should, not much can go wrong. But my problem is that my clutch has about 150K miles on it, very old, and all the fingers on my pressure plate are so tired that when compressed they don't fully release the disc.
Good Luck with troubleshooting.

Re: hydrolic clutch questions

Some have an adjustment between the slave cylinder and the throw-out arm. If it has a hydraulic throw-out bearing, I don't think there is any adjustment.

Re: hydrolic clutch questions

Will is correct....the internal slaves arent adjustable....but going by tyhe year of the truck...it should be external...though i cant claim much knowledge about anyhting foreign!

Re: hydraulic clutch questions

so you are saying that it isn't the clutch, but instead, somewhere along the line it got air in the line but is not leaking out fluid?

Re: hydraulic clutch questions

It is the pressure plate as stated earlier...They all get like that after a while. You could try bleeding it but I doubt it will make a difference.

Re: hydraulic clutch questions

there is always the "freeplay" adjustment, its how much the pedal moves before engaging the master cylinders input rod.

its basically what you adjust to compensate fot eh clutch wear.

Your chiltons should guide you.

Ive seen the adjustemnt on Izuzu trucks, never messed with any mazda stuff that I can recall.

Re: hydraulic clutch questions

My 2 cents on hydraulic clutch systems -----

THEY SUCK! when I think this, it is very loud!

Damn hydraulic clutch replacement cost me over $400 not to mention it delayed my 33" tires a month.
