Subject: RE:ZF6 clutch or transmission failure, CRAP! by CentralCoaster on 2008/2/18 2:09:46 Anyhow, some news: I'll no longer recommend a ZF clutch on an OEM 84-85 vette flywheel. The outer edge of the clutch hangs past the friction surface a bit, but still grinds against the flat surface around the bellhousing bolt holes. It actually pulled a chunk out of the edge of the clutch, and also appears to cause uneven loading on the clutch, which may be related to the clutch slipping (with only 200 rwhp). And.... the Chinese "Perfection" clutch was actually fractured, just waiting for an excuse to grenade. Also anesthes may have something right where he says the clutch fork alignment is causing the slave to preload the clutch. Unfortunately I just sold him my longer ZR1 pivot stud for 1/2 what I paid for it. I'll try just shimming the stock pivot stud further out, or maybe spacing the slave cylinder rearward a bit. Right now I'm waiting on a new clutch set to come in (3rd in 22 months). Hopefully the Luk set isn't Chinese too. In the mean time I guess I'll swap the Hurst onto the new unit. |
