09952-99310: Air pump
09950-69710: Attachment
Procedure
1. Install the special tool into the oil level hole.
2. Connect an air pump into the special tool.
3. Rotate the driveshaft and the propeller shaft clockwise sev-
eral times and then apply the specified pressure for the test.
NOTE:
Apply low initial pressure of 20 – 40 kPa (0.2 – 0.4 kg/cm
5.7 psi) first, then apply the specified pressure.
Leakage test pressure: 100 kPa (1.0 kg/cm

Do not exceed pressure of 110 kPa (1.1 kg/cm
psi) or damage to oil seals will result.
4. Once stabilized, the pressure should remain steady for at
least 5 minutes.
If the pressure does not fall, sealing performance is correct.
