[urq] Clutch for 3B into 016 urq

[Claus Vegener]

The "problem" with Sachs is, that the under-rate their clutches (to be 
safe?) so in the first place
I bought from 034 a SPEC clutch rated at 800 Nm because the 707 is only 
advertised at 560 Nm as far as I remember.
 And the SPEC have to be "burnt in" over 800 km and it did not really help 
and a year after it was just slipping.
I think the springs were too weak. You did not feel, that you have to step 
harder on the pedal.
So do use the Sachs. It is strong and reliable and I have used that pressure 
plate for 12 years w/o problems at my
200 20V from 90 and later on on my Urq-83 witch in the first place was a 2.5 
litre stroker with  20V 3B head  and later,
 when the JE pistons suddenly get too small in the bore, in the 3B 
replacement engine (stronger rods).
As the clutch is a difficult/time consuming unite exchange, I can only 
advice to choose a reliable one in the first place.
Just my experience
Claus
