1. Bleed screw
Keep bleeding until all air has escaped from line.
Make sure no air bubbles remain in oil supply line.
Tighten bleed screw.
Wipe any oil spillage.
Check small oil lines of pump. They must be full
of oil.
If not, run engine at idle speed while manually
holding pump lever in fully open position. Do not
activate throttle lever.
CHECKING OPERATION
On Watercraft
NOTE: Oil line supply must be full of oil. See
bleeding procedure above.
Start engine and run at idle while holding the
pump lever in fully open position. Oil must ad-
vance into small oil lines.
NOTE: The engine should have a rich mixture,
idling irregularly and emitting smoke at exhaust
outlet.
If not, remove pump assembly and check the
pump gear (717 engine) or shaft (787 and 947 en-
gines) for defects, replace as necessary. Test
pump as describes below:
NOTE: Through normal use, oil level must not
drop in small tubes. If oil drops, verify check valve
operation. Replace as necessary.
Bench Test
The oil pump must be removed out of watercraft.
Connect a hose filled with injection oil to main line
fitting. Insert other hose end in an injection oil
container. Using a counterclockwise (reverse po-
sition) rotating drill rotate pump shaft. Oil must
drip from fittings in parts of rotary valve cover
while holding lever in a fully open position.
TYPICAL
1. Supply oil line to an oil container
2. Hold lever in fully open position
3. Counterclockwise (reverse) rotating drill
4. Oil must drip here
For an accurate test, each port should be checked
separately to ensure equal delivery on both ports.
To obtain a precise result of the oil pump delivery
rate, rotate it counterclockwise at 1500 RPM for a
total time of 30 seconds.
NOTE: To ensure accuracy of test, oil lines should
be completely filled before starting test.
