•
It is important to shim the input bevel pinion and
the crown wheel if the gear set or housing has
been replaced.

Measure dimension K at the input bevel pinion,
taking into account the deviation (2) with sign as
stated on the crown wheel from the basic dimen-
sion of 77.50 mm (3.0512 in):
e.g.: K = 77.50 mm + 0.20 mm = 77.70 mm
(3.0512 in + 0.0079 in = 3.0590 in)
•
Measure housing dimension G:
If G deviates from the housing basic dimension
of 75.50 mm (2.9724 in)
the two places after the decimal point are stated
on the housing neck:
e.g.: G = 75.45 mm (2.9705 in)

If no deviation is indicated on the crownwheel and
no dimension is indicated on the housing, then the
unit conforms to the baseline dimensions, meaning
that the required shim thickness is 2 mm (0.0787 in)
(77.5 mm-75.5 mm/3.0512 in-2.9724 in) .

Calculate required thickness of spacer D:
D = K - G
e.g.: D = 77.70 mm - 75.45 mm = 2.25 mm
(3.0590 in - 2.9705 in = 0.0886 in)
