3. While rotating driveshaft and propeller shaft clockwise
severa! times, apply specified pressure for leakage test.
NOTE:
Apply low initial pressure of 20 - 40 kpa, (0.2 - 0.4 kglcm2;
2.8 -
5. 7 psi) first, then app/y specified pressure.
Leakage test pressure: 100 kPa (1.0 kg/cm
2 ;
14.2 psi)
IACAUTION
1
Do not exceed pressure of 110 kPa (1.1 kg/cm
2
