Table 3-51. Anchor Winch Torque Converter Troubleshooting (Cont).
MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
2. Poor performance and overheating of converter (Cont).
NOTE
Pressure on gauge should be between 45 and 65 PSI (2824.3 to 4589.5 gm sq cm). Stop engine
and observe oil pressure gauge hand. If air is present in the converter chamber, the gauge hand
will not move immediately to zero, but will hesitate on the downward movement. Also note fluid
level in re- serve tank. If air is present in the converter, the fluid level in the reserve tank will rise
and may even overflow the tank. (NOTE: If the pressure gauge hand goes right down to zero the
instant the converter stops and if the fluid level in the re- serve tank does not rise after stopping
the converter, there is no air in the chamber). If air is found to be present in the system after the
orifice filter has been cleaned and replaced, the procedure for bleeding the converter explained
under malfunction 2, step la, above should be followed to eliminate air and gain complete fluid
fill.
Step 2.
Check for low basic pressure.
This can be checked by direct reading on the pressure gauge. It should read
between 45 to 65 PSI (2824.3 to 4589.5 gm sq cm).
a.
Check fluid lines for leaks and restrictions.
b.
Check for clogged filter.
c.
Check seal drains for excessive leakage.
d.
Check the accuracy of the gauge.
e.
Charging pump could be replaced.
Refer to Direct Support Maintenance.
NOTE
If basic pressure is too low, the fluid passing around the blades in the converter housing
becomes turbulent and causes an undue loss of efficiency with resultant overheating.
