Today we tried to fill the hydraulic clutch system from the slave bleeder but couldn't get the all the air out. The design of the slave cylinder puts the bleeder valve on the lower right side of the cylinder. So I removed the slave cylinder and ziptied the pushrod in just in case and let it hang vertical so the bubbles can rise up out of the cylinder and up the hard line. Tomorrow I'll push another 60cc's up from the slave bleeder valve and hopefully push the air that was possibly trapped in the slave cylinder.
Before I installed the new slave cylinder I took it apart because the last one didn't have many miles on it. Inside I found a little bit of grey pastey stuff, you can see it on the rag. So I cleaned it up and realized that I needed to smooth out the front corner of the piston. After I deburred it I cleaned it up again, lubed the seal with red brake grease and the outer side of the piston with SylGlide and reassembled it. The previous slave cylinder had a spring, floating inner piston, floating seal and an outer floating piston. The result was premature wear to the pushrod tip, clevis pin and hole. In my opinion not a good design since the clutch arm moves in a small arc.
