4.6.3.7 Clutch pressures, lube pressures, internal leakage, and input torque. To determine
conformance to 3.4.11, 3.4.12, 3.4.13, 3.4.14, 3.4.4.c, 3.4.4.d, 3.4.18.2, 3.4.18.3 and 3.4.18.4:
a. Apply 56 to 76 L/min flow into lube port L.
b. Apply 1830 +35 kPa to control port M and hold that pressure.
c. At the forward (CW) input speeds and at the reverse (CCW) input speed listed in
table XI, in both the geared steer and clutch brake modes, observe that the
requirements as specified in table XI are met at each steer lever position indicated
in tables IV and V.
