IMPORTANT: Danger of mix-up:
If none of the markings described above are present, then the eccentric shaft will be a new-version shaft.
The new-version eccentric shafts are identical parts.
Depending on the side on which the lever for the torsion spring and the magnet wheel are fitted, the eccentric shafts are used for cylinders 1 to 4 or 5 to 8.

NOTE: Lubricate eccentric shaft at bearing positions.

Replace needle bearing (1).

IMPORTANT: Needle bearings break off very easily when installed.

Carefully press needle bearings (1) apart at split position only to such an extent that they can be fitted over eccentric shaft.
