I tried to bleed the hydraulic clutch from an 89 1 ton that I am using on my 69 K20. I am getting fluid to bleed out as directed by the repair manual and am no longer getting air bubbles. However, I am getting no movement of the clutch fork. This setup is a complete swap to my 69 as I am using the 89's 454, bellhousing, clutch fork, slave and master. Installation of the slave and a new clutch and throw out bearing were in September of 2003 while the truck has been dismantled, so it has set for about 10 months. A friend recommended disconnecting the slave from the bellhousing to see if the push rod will move without the clutch pressure. Another option would be to try to manually move the clutch fork to see if that helps. Any suggestions before I do anything?
