ok so when i chucked the new motor in i got a new clutch for it, but it seems the throw is different in this.

with the clutch fully in its just not enough to fully disengage the clutch, can get it in gear but can feel the resistance as i shift, and the clutch is pretty much fully engaged with less then an inch pedal movement from the floor,

i bled the whole system with fresh fluid and the pedal still has lots of travel before i get good resistance from it, inspected the rod that actuates the clutch fork and it seems to be ground down a bit so maybe someone has modified it before,

anyway has anyone had this problem before or anyone got any ideas to fix the problem?

Might need a longer pushrod from the slave cylinder to the fork, maybe fab one from a piece of steel rod with the ends rounded off with the grinder.
I haven't pulled mine out yet so don't have the numbers for clearance between the throwout bearing and the clutch fingers. maybe there will be something on the wiki.

well the pushrod is hard up against the fork, its just not traveling out enough, i think i need to get under the dash and adjust it there, thats the next try

happened to me when I put a new one in

You've gotta bleed that clutch properly, that's where your problem is!! If all you did was drop the gearbox, swap old for new (i.e. identical for identical) it is without a doubt the clutch that needs to be bleed

if you get the clutch to a stage, where it's just sticking a little bit, you can either live with it for the few days it'll take to settle in, or you can leave the car for a couple of days to get the last little bit of air out

cheers

Yep & did you check this before you bolted the clutch to the flywheel?


m in a rush, but the pressure plate is different height or something.

Disagree, you only get air in the hydraulics if you disconnect a cylinder of if one of the cylinders is sucking air.

if the pin is to tight ( from the slave to the clutch fork) It makes the clutch work to or direct. (theres no free play)
This has happen to me, when i went from non turbo to turbo motor. I used the non turbo gearbox and clutch slave but turbo clutch. pin was to tight and was making the clutch slip, I had to shorten my rod, to the slave.

Hope this makes some kind of sence

yeh it makes perfect sense, i have already shortened this rod and it is tight against the clutch fork but not pushing it at all

also to all who say bleed it, i have already bled the system, also mentioned that in the first post, there is no air in it, so leaves me to think the turbo fork actuating piston or master cylinder has a longer throw or i just need to get under the dash and adjust the pedal, going on what ive read today in the nissan manual a pedal adjust should do it.. hopefully

I have no pedal adustment under my dash, Thats why i had to shorten the rod.
The clutch works fine, but low down on the floor.

had a look at it today, it has got adjustments under the dash, and theres about 1 inch freplay so that cant be helping ill fix that tomorrow, also noticed the master cylinder is 5/8 and the fork actuating piston is 3/4, are these ment to be matched or do the fractions just display the piston size?

now I am hung over, so short and sweet, I recall adjusting the clutch pedal, to allow more push into the clutch master cylinder (which in turn should push the slave further too)

it's pretty easy from memory too

Both should be the same size it would be easier to push a 5/8 master but would have a longer travel. Find a 3/4 master!
I am running a larger master on my brakes (GQ and it is harder but stops better.

Clutch pedal needs adjusting under the dash
Clutch you should feel from start to finish on pedal travel
Not just at the bottom

Smokey is right
New slave cylinder about $40 and the master cylinder are around $60 ish
Wouldnt be fugged rebuilding them for that money
They are a very basic set up
Hydraulic over hydraulic

IF the clutch is not fully disengaging,
DONT shorten the slave cylinder to fork push rod
Itll make it worse
