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 (3.0511 in):
e.g.: K = 77.50 mm + 0.20 mm = 77.70 mm
(3.0512 in + 0.0079 in = 3.059 in)
•
Measure housing dimension G:
•
If G deviates from the housing basic dimension
of 75.50 mm (2.972 in) the two places after the
decimal point are stated
•
on the housing neck:
e.g.: G = 75.45 mm
(2.9705 in)

If there is no deviation marked on the crown wheel
and no size on the housing the sizes are in compli-

ance with the basic sizes, which means that the re-
quired spacer thickness is

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