Table 3-40.
Hydrostarter - Fluid Emerges Around Rubber Boot
of Hand Pump - Troubleshooting.
MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
1.
Fluid emerges around rubber boot of hand pump.
Step 1.
Check for damaged piston seal rings.
Replace the seal rings and leather back-up rings on the pump piston. Refer to
paragraph 3-104.
Table 3-41.
Hydrostarter - Cranking Cycle Too Short -
Troubleshooting.
MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
1.
Cranking cycle is too short.
Step 1.
Check for faulty pressure gage.
If gage is reading higher than actual system pressure, oil volume in the
accumulator will be less. Replace gage.
Step 2.
Check for excessive internal leakage in hydrostarter.
Refer to table 3-32.
Step 3.
Check for accumulator precharge too high.
With the fuel shut off to prevent engine from starting, crank the engine until all oil
is used. If the gage then registers zero pressure, install a gaging assembly on the
air valve and drop the precharge to 1250 psi (1695 kPa). Repeat cranking cycle. If
gage will still drop to zero at end of cranking cycle, reduce precharge to 1000 psi
(1356 kPa).
