4.6.2.2 Hydraulic backlash. To determine conformance to 3.4.2, the degree of hydraulic
4.6.2.5 Pump leakage. To determine conformance to 3.4.5.1 and 3.4.5.2, the pressures
specified in 3.4.5.1 and 3.4.5.2 shall be applied to case port and both pressure ports while pump is
not rotated and while pump is rotated at 10 to 20 rpm. The rate of external leakage shall be
measured.
