Reconditioning the shift mechanism Types of shift mechanisms
Shift mechanism type 1
For the models 280, 290, 285, 285A and 290A there are 3 different types of shift mechanism. The first type was installed up to and including serial no PZ 2829528. As from serial number PZ 2829529 the second type – where the ball, spring and the locking wire were removed – was installed. There is a somewhat different dismantling and assembly sequence for each type. The third type and the shift mechanism for models DP and SP are described on pages 68–72.
