The contact pattern required on the bevel gear set, however, is decisive. If this is not achieved -
see contact pattern check on page 3-285, correct the pinion position with a corresponding shim.
As an alternative, a basic setting of the required pinion position can be made, e.g. when
assembling a new part - as shown below (figure 7577AAXR086
~ 088).

We recommend to reinstall the shim
found during disassembly (e.g. S = 1.20
mm see disassembly instructions, page
3-276, figure 7577AAXR082.) into the
inner bearing hole/pinion bearing.

Read pinion dimension X (pinion basic
dimension e.g. = 148) from pinion, or
determine it in case of a + or -deviation
from pinion dimension due to production
(value concerned is marked by hand on
the pinion, e.g.+ 0.1).
Pinion dimension X (w or
-deviation value) = 148.0 mm
Pinion dimen. X with indication of + 0.1
deviation = 148.1 mm
