Just switched 4sp to 5sp, is clutch wrong one?

[dogma420]

Hello guys, well I just finished with my 4sp to a 78 5speed conversion.

but....

The clutch acts like its disengaged 90%, (it will move barely when floored)....what I was wondering, is that I had an old (10 yr) clutch kit in my closet, and I used that...it was for a 73 240....I was assuming that 70-78 clutches are all the same....are they?

I got a new 78 280z slave for the clutch, and I think I bled it enough, probably couldn't hurt to bleed it more....

The clutch feels like it is out of adjustment, but with the 78 slave there's no way to adjust the clutch.

Any suggestions would be great!

I had the flywheel resurfaced, new slave, new tranny fluid....bled the slave by having someone pump 10 times then open the bleeder, repeating that like 10 times until clear fluid came out. Did not mess with my master clutch cylinder, which was working fine before the 4sp was dropped.

Thanks!

Thanks Les!

That clears that up.....ok so this is what that says:

I'm afraid that I have no "quick fix" for you. You will have to

drop the tranny (again!) and either use a 280Z throwout bearing

collar or replace your clutch/pressure plate with a 280Z type.

I don't have any probs pulling it out, in fact, i'm sure the 2nd time around will be much quicker....

Does anyone know if the '73 240z clutch disc I used can be saved, and I can just go get a pressure plate for '78 280z? This could save me a little $$....also, I know that MSA sells just standard pressure plates (I was going to just run this clutch into the ground, so the stock setup is ok)...until I rebuild my 2.4 into a 2.8 block up to 3.1....so if anyone knows 'the cheapest' place to get a pressure plate (and if my 73 clutch disc is useable), please let me know.

Thanks!

The question that needs to be answered is did you use the bearing carrier from the 4 speed trans or the 5 speed? If you used the 4 speed carrier, you have some other problem, if you used the 5 speed carrier you can pull the trans and swap it with the 4 speed and all should be fine with you 240 clutch and pressure plate.

You could try making a shorter rod that goes between the clutch fork and slave cylinder from a piece of bar stock.
