Using a feeler gauge and precision straight edge, measure the clearance between the 2 rotors and precision straight edge.

Standard side clearance:

0.085 to 0.135 mm (0.0033 to 0.0053 in.)

Maximum side clearance:

0.16 mm (0.0063 in.)

Using a feeler gauge, measure the clearance between the driven rotor and oil pump body.
