Another clutch bleeding question.

Ok, finally have a few moments to work on the truck again. Trying to finish up the hydro install. I rigged up a sweet bench bleed system that holds the slave cylinder in 3/4 of the way as per recommendations on here.

Should I have a perfectly firm master cylinder rod, meaning no movement whatsoever, or will there always be a little bit of play there? I've got it very firm with about 1/8" rod travel before it gets too firm to move at all. More bleeding, or...?

Ugh. Well, I had it pumping bubble free and it felt nice and firm, though there was about 1/8 - 1/16 inches of slightly spongy travel. I installed, and was able to get the truck to shift into reverse, but no other gear. I think I'm giving up for today.

No, there was mo bubble in the plastic fitting on top of the master, I bled it with the master upside down.

In order to bleed the clutch you need to have it all installed on the vehicle then wedge a board somehow to prevent the clutch fork from moving then pump the pedal and bleed to slave. If the clutch fork is allowed to move you'll never get all the air out of the system.

I thought I achieved that by the way I rigged it up on the bench. I prevented the slave from moving while bleeding, and kept it almost entirely compressed. Is it a problem to then transfer it to the truck, allowing the slave to extend even though the system is sealed at that time? Not sure how it would make much difference.

When I did mine I filled the master with the line connected and the end capped. I then tilted it at all angles to get all the bubbles out. Then I hooked the line to the slave with the bleeder open and proceeded to fill the master as needed while the slave gravity bled.

I then capped it all and mounted the master and hung the slave down near the trans. My buddy pumped the pedal while I cracked the bleeder with it titled to get the bleed as high as possible.

When I mounted it up and put it on the fork it was hard as a rock. I didnt restrict the slave at all just let it hit the stop that prevents the rod from popping out and it worked great. No sponge.
