Mount pressure device (078) onto end disk (89c).
Compress the disk pack, to do so press the pressure device (078) together using a lever press up to stop.
The marking ring (smaller arrow) is then still visible.
Use a feeler gauge to measure the clearance (L) at three points between the snap ring (90h) and end disk (89c).
During the measuring procedure, the snap ring (90) must lie against the upper contact surface of the groove in the external plate carrier (83a).
Use corresponding snap ring (90h) to adjust clearance (L) if necessary.
The snap rings (90) are available at sizes 2.6 mm, 2.9 mm, 3.2 mm, 3.5 mm, 3.8 mm and 4.1 mm.
