4 Dimensions and tolerances
Engine manufacturers should use the tolerance H7 for the female register diameter.
In the figures and tables, except for Figures 2 and 5 and Tables 2 and 5 (shaft end with tang drive), the
diameter d 2 corresponds to the diameter d specified in ISO 6519.
NOTE The flange configuration can optionally be rotated relative to the pump housing.
