Rated inlet fluid temperature ("F): +275 +0, -10
21.5; maximum allowable flow at no-load
Rated fluid flow, max (gpm):
operation is 23.0 gpm.

Rated torque (lb-ft):
Rated drive shaft speed (rpm): 4000
Automatic shutoff control: The cutout switch shall be normally closed;
it shall open at cutout speed. The switch shall withstand a surge current of
2 amperes at 28 volts inductive load at -65°F.
Drive shaft cutout speed (rpm): 6700

The
No-load operation: The starter shall be operated for two minutes.
starter free-running speed obtained during this test, or the maximum speed
attained before automatic cutback, shall not be less than 8000 rpm.
Proof pressure test: With the load device adjusted to limit starter
output drive speed to rated speed rpm and at rated inlet temperature, the
starter shall be operated for five minutes at 5000-psig inlet pressure and
1250 psig outlet pressure. There shall be no leakage from the starter
sufficient to form a drop, except from the output shaft seal from which a
maximum leakage of 5 cc per hour is allowable.
Endurance test: The starter shall be subjected to a 1200 cycle endurance
test as outlined herein. The following schedule for fluid inlet temperature
and fluid inlet pressure shall be maintained:
