Slave

[turbohead7]

Doesn't sound like a slave or master. Judging by your post I'am assuming the clutch pedal felt somewhat normal. So here's a lesson in clutch operation. The clutch, at rest, is always engaged. When you step on the pedal you are depressing the fork lever through fluid transfer from the clutch master to the clutch slave cylinder, therfore when either of these fail you typically will have trouble DISENGAGING the clutch. The exception to this is a mal-adjusted clutch master, if the pushrod length is too long, the slave will act on the fork even at rest which can cause slippage. Worse, every time you step on the pedal you will be over-extending the slave which will eventually tear your throwout bearing in half (clutch freeplay needed). Clutch ENGAGEMENT is a normal action of the diaphragm spring on the pressure plate at rest. The release fork, when depressed, changes a push to a pull and pulls on the throwout bearing which is attached to the center of the pressure plate on the fingers of the diaphragm spring----thereby releasing the clamping force on the clutch disc. This is how your clutch works. First make sure you're actually engaging gears when you shift, I think your engine's power is being lost somewhere back by the transmission---but if not I hoped this helped you, If you're going to fix anything you need to know how it works.
