please help, clutch wont disengage 5speed swap.

Get under the car and have someone push the clutch and see if the slave is fully extending?

You cannot see it extend when it is installed. If you unbolt it and hold it in your hand while pushing the piston against the bellhousing, you could have someone step on it while you watch it extend.

Sounds like the clutch disk is in backwards.

well its a brand new pilot bearing and clutch so i am stumped lol ill be home this weekend, with a new bleeding technique i just learned that pushed the fluid from the slave to the master!!

[bmwstudent]

but if it isn't disengaging fully couldn't the fact that the system isn't bled real well be the issue?

Yes absolutely, but with all the posts advising on bleeding I was looking for other answers. Just a thought.

What are the conditions of the master and slave cylinders?

I've seen this happen with semi trucks before. I don't know if this is your problem but if the pilot bearing is in bad shape and locking up it will continue to spin the input shaft when you step on the clutch. If you step on the clutch with the car in gear and it still want s to drive itself, then the input shaft is still spinning. Wether it's from the disc hanging up or the pilot bearing seized up, only disassembly will tell.

Did you put a new disk, pressure plate and flywheel? What did you use, OEM? Are there any differences in mounting and do you have a factory manual? It might help to see the parts breakdown between the 2.

I know in auto to manual swaps on other model cars I have done, there are certain plates that are on a manual and not on a auto that "space" the trans out the right distance. I have not done an E30 so only trying to give you ideas. I will try to help by looking at my Bentley manual.

anyone?

bump

[Chriskbmx]

well i was thinking if the clutch fork doesn't move as far because of the pivot pin wouldn't that cause it to not fully diengage? and there shouldn't be anything there, but idk if this is relevant but i used brakelene to clean off the flywheel and pressure plate from grease.

[Turbotalon92]

Good point, would have been a pita to get tranny on if not aligned. If pivot is worn, it shouldn't cause an issue with it always being engaged. Would be hard to put into or change gears as it wouldn't disengage. Sounded like in your description it is always engaged? You may need to pull it back off, could be something stuck between disk and clutch/flywheel.

[Chriskbmx]

also i looked it up on realoem and it shows that the car should have a sprung friction disk and mine isn't

[Chriskbmx]

yes i did, but even if i didn't if the transmissin imput shaft whent through the friction disk and the pilot bearing wouldn't it alighn? and what exactly would the pivit pin cause it it was bad?
