Clutch Alignment?
I just scored a complete (what appears to be low mileage) dual clutch assembly from a fellow Rennlister. I received the ring gear, intermediate ring, presure plate, both discs, release arm, and the throwout bearing. The alignment marks (yellow arrows) on the discs are visible but the pressure plate and intermediate ring have been seperated before I received them and I dont sem to know/see any alignment markings. There are three equal diameter pins that index the two, so how do I determine the original and balanced orientation?

one of the pins is slightly larger than the other two thus the assembly will only fit together one way.
The discs if marked should have the dots 180 degrees from each other.
Dont forget to set the stub shaft depth prior to installing the clutch pack.
fit the guide tube and shaft,
then make a mark around the shaft at the rear of the guide tube on the stub shaft after you have inserted fully then pulled the stub shaft back about 3 to 4 MM.
This will prevent the stub shaft loading the drive line and put the riding section of the shaft centered in the pilot bearing

The pressure plate indexes easily every 120 degrees as all three pins are the same diameter. Ive read the manual and the commentary on this site describing the two different sizes, but dont understand the physical part having three identical pins. Thats why I asked.

what was the clutch pack supposed to be from?
It looks like an early assembly and these might have had the three pins of the same size,
the later versions had one thicker pin
You could mark it,
then put together,
if you get a vibration then you turn the PP two more times.
If that doesnt work then you turn the I plate two more times.
Or remove the flywheel then take the whole assembly to the machine shop and have it balanced they will mark it
