The procedure should be exactly the same as the brakes:
1. Make sure the master cylinder is either bench bled, or sitting dead level when on the truck so the air can escape.
2. Double check all the fitting to insure everything is tight.
3. Have your partner pump the pedal 3 times and hold it down, while you open the bleeder valve on the slave cylinder.
4. Let your helper know when you've closed the bleeder valve so they can let the pedal come back up.
5. Check the master cylinder often to make sure it doesn't run out of fluid.
6. Repeat steps 3-5 until all air is expelled.
And if that doesn't work, one tip I've used that always seems to get the job done - block the clutch mechanism with a piece of wood or a clamp or anything that will immobilize the clutch fork. When bleeding brakes, the shoes or pads are pressing against the drums or discs allowing pressure to build up and force the air out. Because a clutch fork can move, it can be very difficult to build enough pressure for effective bleeding. Air bubbles can just move back and forth with the fluid if not squeezed hard enough to force them out.
