FUEL INJECTOR PUMP CALIBRATION (Cont).
2 .
Set rpm to 150, with throttle lever (17) in wide open throttle position. Minimum flowmeter
reading should be 35.0 cc. Open shutoff valve (5). Minimum transfer pressure gage (6)
reading should be 12 psi (83 kPa). Close shutoff valve.
3 .
Set rpm to 600, with throttle lever (17) in low idle position. Flowmeter reading should be
12.5-16.5 cc. Minimum throttle advance gage (13) reading should be 1.5 degrees.
4 .
Adjust position of servo adjusting
screw (22) to obtain 2.25 degrees
cam advance indication on throttle
advance gage (13). Disconnect
positive test lead (14) from shutoff
solenoid terminal, Connect positive
test lead to cold advance solenoid
terminal. Housing pressure gage (7)
reading
should
0-1 psi
(0-6.9 kPa). Disconnect positive test
lead.
5 .
Set rpm to 1500 and rotate throttle
lever (17) to obtain a flowmeter
reading of 21 .5-23.5 cc. Throttle
advance gage (13) reading should be
2.5-4.5 degrees. Housing pressure
gage (7) reading should be 8-12 psi
(55-83 kPa).
6 .
Set rpm to 2000, with throttle lever
(17) in wide open throttle position.
Flowmeter
reading
s h o u l d be
47.5-51.5 cc. Throttle advance gage
(13) reading should be 0.5-2.5
degrees. Housing pressure gage (7)
reading
should
be
8-12 psi
(55-83 kPa).
7 .
Set rpm to 3200, with throttle lever
(13) reading should be 4.25-6.75
8-12 psi (55-83 kPa).
(17) in wide open throttle position. Throttle advance gage
degrees. Housing pressure gage (7) reading should be
CAUTION
Ensure that throttle lever (17) remains in low idle position no longer than
length of time required to record gage readings. Failure to follow this
caution may result in damage to fuel injector pump.
8 .
Place throttle lever (17) in low idle position, Maximum throttle advance gage (13) reading
should be 10.0 degrees. Housing pressure gage (7) reading must be 8-12 psi (55-83 kPa).
9 .
Set rpm to 4000, with throttle lever (17) in wide open throttle position. Minimum flowmeter
reading should be 40.0 cc.
