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 gage hand. If air is
present in converter chamber, gage hand will not move immediately to
zero, but will hesitate on downward movement. Also note fluid level in
the reserve tank. If air is present in the converter, fluid level in the
reserve tank will rise and may even overflow tank.
NOTE
If pressure gage hand goes right down to zero the instant the converter
stops and if fluid level in the reserve tank does not rise after stopping
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 1a 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 gage. It should
read between 45 and 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 gage.
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.
