CAUTION!
Part numbers are listed here for reference only. Always check with

In order to avoid damage due to improper assembly, check the
following after replacing input shaft: Fig. 3 Allocation of input shaft/needle bearingInput shaft diameter

a: 27 mm (1.062 in.) 012 311 123 D
a: 29 mm (1.141 in) 012 311 123 Input shaft must be able to be guided in.Input shaft must have no play.

Dimension -a- from lower edge of straight-edge to upper edge of needle
bearing: 39.5 mm (1.555 in.)
Note:
Measure the dimension from the top edge of the straight-edge and
subtract the height of the straight-edge from the measured dimension. Fig. 4 Allocation of needle bearing
