14) Inspection of Gear Case (for leakage)

1. Drain gear oil.
Remove upper oil plug 1 and connect a commercially
2.
available leakage tester to this hole.
3. Apply specified pressure to gear case, and check if the
pressure is maintained without further compression for 10
seconds.
Specified Gear Case Maintained Pressure:
0.05 MPa (7 psi) [0.5 kgf/cm
· Rotating propeller shaft while maintaining
pressure and testing with gear oil drained make
it easy to find leakage due to wear of oil seal lip.
· Depressurize gear case and cover oil plug area
with a piece of rag before disconnecting leakage
tester.
Do not apply pressure to gear case over
specified value.
Doing so can cause damage to oil seal.
4. If the specified pressure cannot be maintained, check oil
seals of drive shaft and propeller shaft and O ring of shift
shaft, and propeller shaft housing and water pump case
lower for damages.
15) Inspection of Propeller
1. Check propeller blades and hub for cracks, damages,
wear and corrosion. Check spline for twist, and replace
propeller if necessary.
