MEASURING THE OIL PUMP
DISCHARGE
Measure:
• Oil pump discharge
Out of specification → Check all of the
oil pump components and replace any
defective parts.
Engine oil discharge
(3 minutes/1 cylinder)
100hp, 115hp:
3.20 ± 0.70 cm
(0.108 ± 0.024 US oz,
0.113 ± 0.025 Imp oz)
130hp:
4.80 ± 1.10 cm
(0.162 ± 0.037 US oz,
0.169 ± 0.039 Imp oz)
NOTE:
When measuring the oil pump discharge,
observe the following.
• The engine oil temperature should be 10 -
30 ˚C (50 - 86 ˚F).
• Before measuring the oil pump discharge,
completely bleed any air from the oil
injection system and make sure that no air
bubbles are present in the engine oil
which is flowing out of the oil feed hose.
• When using the graduated cylinder, make
sure no engine oil clings to its walls; oth-
erwise, the measurement will be incor-
rect.
• Use only the specified engine oil of the
proper viscosity. If the viscosity is too
high or too low, the discharge measure-
ment will be incorrect.
• Calculate the rate of discharge per minute.
The longer the measurement time, the
higher the accuracy of the measurement.
