TM 9-2320-387-24-l
REFERENCE INFORMATION
A healthy engine should crank
at least 100 mm when it‘s cold
and at least 180-206 rpm
when it’s warm.
If the engine doesn’t crank at normal
speed, it could be due to a starter or
battery circuit fault or it may be due to
an internal engine problem.
Oil pressure may go as high as 60 psi
(552 kPa) if the engine is cold and
should be 10 psi minimum at idle
speed. You should check the oil
pressure with the STEIICE-R
(test 50)
using 1,000 psi (6,895 kPa) transducer
(blue stripe). Check pressure at idle
and at 2,000 rpm. If pressure is low,
check oil level and condition.
Add or
change oil as required.

ENGINE RPM
STOICE-R TEST 10
I
1. Start Test 10, Engine RPM.
2. Crank or start the engine. Displayed
reading is RPM. Cranking rpm should be
approximately
100-200.
Idle rpm should
be 625 - 675.

OIL PRESSURE
STEhCE-R TEST 50
1. Install STEIfCE-A 0 to1000 PSI (O-6.895 kPa)
transducer (blue stripe) in place of oil pressure
sending unit.
2. Connect to STEIICE-R TK connector J2 or J3.
3. CAL with engine off.
4. Start engine.
Run test 50. With the engine
warm, oil pressure should be 10 psi (69 kPa)
minimum at idle and 40-45 psi (275-310 kPa) at
2.000 rpm. Pressure may go as high as 80 psi
(552 kPa) when the engine is cold.
