CHECKING OPERATION
Oil Pump
On Vehicle
NOTE: Main oil line must be full of oil. See bleed-
ing procedure below.
Lift rear of vehicle and support with a mechanical
stand. Unplug small oil lines from pump. Start
engineandstopitassoonasitfires.
Check that oil in small oil lines has been sucked up
(this will be indicated by a clear section of small oil
lines). Repeat the procedure until this condition is
attained.
Reconnect small oil lines, start engine and run
at idle while holding the pump lever no. 3 in ful-
ly open position. Oil columns must advance into
small oil lines.
If not, remove pump assembly no. 4 and check
the pump gear and drive shaft (if applicable) for
defects, replace as necessary. Test pump as de-
scribes below.
NOTE: Through normal use, oil level must not
drop in small tubes. If oil drops, verify check valve
no. 5 operation in injection nozzle. Replace as
necessary.
Test Bench
Connect a hose filled with injection oil to main line
fitting. Insert other hose end in an injection oil
container. Using a clockwise rotating drill rotate
pump shaft. Oil must drip from outer fittings while
holding lever in a fully open position. If not replace
pump.
Check Valve
For all engines, check valve no. 5 is part (built-in)
of injection nozzle.
To verify the check valve, proceed the same as for
checking pump operation on vehicle. First unplug
oil line from check valve. After restarting the en-
gine, check that a clear section in small oil line is
present. Reconnect oil line.
Run engine at idle. Oil column must advance. If
the check valve is faulty, oil column will go back
and forth. Replace if so.
