I've never heard of someone extending the slave rod to get it to
release.? Most are lack of travel in the master (longer rod) that
needs to be cut so it can travel further and fully engage the
slave.
check on rennlist about modifying the master.?
How about the release bearing, you did press in a new bearing.?
Is that "spinning" ok?
Just tossing out some ideas as like Colin noted, usually it's the
discs when there's chatter, but the early dual discs engage higher
and slower than the single discs, so pedal/master/slave travel
sometimes affects how the system grabs.?
My 79 has all original discs etc, I added a new slave and I can
feel the grabiness (is that a word :D) due to it just being
resurrected after sitting for better part of 20 years.? The more I
drive, the better it seems to operate.

Not a spec clutch kit. Factory parts with discs
from 928intl. New slave and master.? Extended the slave rod to
get positive release (matched old slave)
Are these the Spec clutch components?
Have you done all the hydraulics?? Clutch master and
slave??
How does the pedal feel when engaging and dis-engaging?
Is there a break-in procedure from Spec (if these are
Spec)?
The double disc clutches can be a pain, but getting the
intermediate plate pinned is a good start.?
Another thought, on some of the early double discs, there
is a "front" and "back" disc.? Does the spec have front
and back, or are they both the same?

Hey group.?
I've reached the end of my patience rope
with this 928.?
I have replaced or resurfaced all of the
components of the clutch. I still get a chatter on
engagement.? The intermediate plate is pinned and
straighted. New clutch discs. Resurfaced flywheel and
brand new pressure plate.?
I'm looking to see if there is a local
expert that can help with the diag on this in the
tacoma area. I'm clearly missing something.?
