4 Dimensions and tolerances
4.1 General
Engine manufacturers should use the tolerance H7 for the female register diameter.
ln the figures and tables, except for Figures 2 and 5and Tables 2 and 5(shaft end with tang drive), thediameter d2 corresponds to the diameter d specified in lSO 6519.
NOTE The flange configuration can optionally be rotated relative to the pump housing.
