    hey folks,
    i have a toyota truck with chevy driveline(350/sm465/np205).
    i'm having a problem with the clutch, master cylinder and slave cylinder are chevy (both brand new)but i cant get enough movement to push the clutch fork back.
    first question: how far does it need to go! it's gotta go all the way back or just 1.5" or whatever.
    second question: if it doesn't have to go all the way back, what should i look for to fix?(you think i put the disk backward or ?????)
    i appreciate any help in advance.

    1. Do you get any movement off the throw out fork?

    2. How much pedal movement do you get/have. Mine moved quit a bit before it starts to move the fork.

    3. Is this something that just happened, or has it been that way since you installed the new MS and SC?

    They can be a PITA to bleed. Make sure they are completely bled.

    Even still a pwer bleeding can leave air in down at the SC. Here is what I suggest. Bleed the SC by pushing the piston rod in while you open the bleeder screw. The trick is getting the screw closed again before it bottoms out. Do this 3 or 4 times and then see how it feels. My GM mechanic buddy says the air in the lines likes to sit down there at the SC.

    Otherwise I am think that you do have enough pedal movement required to push the throw out fork. It sems like I have about 6 inches of pedal travel before it bottoms out on the floor.

    That is all I can think of right now.

    Umm did you just convert this from a clutch linkage to a Hydro clutch???

    If so, the forks are DIFFERENT!!! /forums/images/graemlins/ignore.gif

    are you using the pedal from the toyotsa or are you using a chevy pedal that you swapped in...If you are using a stock Toyota clutch pedal, it is possible that you may have to move the MC pushrod mounting location down the pedal a bit to get more piston travel at a given amount of pedal travel...
