200Q Clutch Slave Cyl Same As V8Q?

[Ben Swann]

I did not get a response on this earlier, I checked ETKA and confirmed the same part no.
for slave cyl. for both V8 quattro transmission and the 200 Quattro.  So that is
apparently not the problem.  4A0 721 261 is used for both transmissions  according to my
version of ETKA.
 
Bleeding makes no difference.  The problem is that the rod does not apply pressure
against the release lever even when at its fully extended length.  I tried a few new
ones for comparison.  When the rod is fully extended, the rod is just shy of touching
the divot in the lever.
 
Is there a different rod that is not specified in the ETKA  - that is the V8 rod is
longer by about 12- 15mm by my estimation?
 
I'm not sure what else it could be - I used a new release lever, release bearing, as
well as 200Q/3b disk and pressure plate.  The only other thing I can think might make a
difference is   Clutch Operating Lever (release lever) 016 141 719A called for on 200Q
is I thnk what I used, but did not thnk about it as the time.  The divot on the lever is
in the correct spot for the rod to hit.
 
I'd really appreciate any advice on this.
 
Ben

I'm trying to determine if the clutch slave cylinder that is in the 200 Quattro should
work OK for the V8 trans I'm installing.

I have the trans in.  The slave was never disconnected, so theoretically should not need
to be bled.  The slave cyl. Did not fit quite as tightly in the bore as otheres I've
seen, but micrometer meaurements were very close between the hole size and the diameter
of the slave.  I compared to several other slave cyl. I had NIB and all were similar and
had the mounting hole as apposed to the earlier 5kt units that had the roll pin.  

So I went with the 200 one that was in the car.  Now the trans is bolted up to the
engine, there is no real pressure exerted via clutch pedal, as if the rod is not hitting
the throwout lever.  I did note when installing the slave, that you could push it in
another 1/2 to 3/4" past the mounting hole before it touched the divot in the lever.  I
presumed that distance would be taken up once the trans was in place and release bearing
pressing against the pressure plate.

Is the Rod on the V8 tranmission slave longer?  Should this be just a matter of
bleeding? 

Is the V8 slave different in more than just the number?
