Clutch Connection

I recently did an engine swap with a friend of mine but after putting it in, i noticed that the clutch pedal wasnt connected. Where could it have come disconnected and how would i fix it?
I know very little about the clutch assembly :-\

Clutch is a hydraulic master/slave design. The clutch master cylinder fluid feed comes off of the brake cylinder reservoir. It's a bluish colored woven hose on the side.

The clutch slave pushes a fork that moves the throw out bearing against the pressure plate springs.

In most cases the clutch master/slave cylinders loose their prime and the clutch pedal seems like it's not attached to anything.

So if you disconnected the slave cylinder then you need to bleed the system. Keep an eye on the fluid level in the brake reservoir. Don't want to run out.

If you are refering to the cylinder on the bell housing that is the slave. The clutch master is on the firewall below the brake booster/cylinder.

Let us know what you find out.

its the one you have to remove the starter to get to (#17 in the diagram)

Luckily that cylinder from my old engine was still good.

Good. It bled out ok? Alex is right in saying that if one is bad the other is close to failure.

Really need to be concise on the parts names. Get's us all confused and tending to reply with wrong answers.

How are the timing and ballance belts?????

belts are rollers are brand new on the new engine - thank god
the compression is 160 psi, so thats good too

However, im having problems with my clutch.

You push it in a little, and the pedal just falls through by itself...the slave cylinder was working perfectly before the engine was replaced (both old and new cylinders were tried and bled correctly) but they still fall through. I tried pumping the pedal/opening the valve on the slave cylinder and theres plenty of brake fluid. No luck.

I dont know why it would break all the sudden, could it be something else?

had a mechanic look at it today (albeit non porsche) and he didnt get anywhere

he says theres a ton of air in the tubes and wasnt able to get them out through any normal bleeding methods.

any suggestions anyone?

I read some 944 maintenance articles and they say you should lift the rear end as much as possible when bleeding the slave cylinder

I tried it with the car level to the ground before.

Tomorrow ill see if this fixes the problem.

yea i spent 6 hours on my clutch cylinder job. i had different people tell me to try and jack up the rear and all kinds of stuff. i ended up getting it after raising the passanger side higher than the drivers.
but also make sure your master cylinder pushrod has MORE than enough play!!!!!! i bled almost a half quart of fluid before realizing i wasnt fully engaging the clutch when releasing the pedal. good luck
