OILING SYSTEM
OILING SYSTEM TESTS
Observe oil flow through all oil distribution hoses.
Air must be purged during the priming procedure.
Small bubbles are acceptable. Large bubbles
must be eliminated through continued priming.
Repair any fuel or oil leaks.
The oiling system on these models can also be
primed using the Self-Winterizing feature if diag-
nostics software is not available. Refer to
OILING SYSTEM TESTS
IMPORTANT:
Always perform visual inspections
to identify oiling system leaks. Make sure the oil
tank is filled and oil supply is not contaminated.
Oil Injection Pump Voltage Tests
IMPORTANT:
Do NOT perform static tests using
Diagnostic Power Supply Tool, P/N 587005, with
internal 9 volt batteries only. This will produce
false results. Refer to
The
EMM
controls the pump by providing ground
through pin 23 (blue wire) of the J1-B connector
and pin B (blue wire) of the oil pump connector.
Use a digital multimeter calibrated to a scale that
reads 12 V (DC) to measure voltage between the
oil pump electrical connector and engine ground.
Connect negative meter lead to ground.
Use an appropriate test probe to connect positive
meter lead to pin B (blue wire) of oil injection
pump electrical connector.
Turn the key switch to the ON position. Observe
voltage at pin B.
•
Voltage at pin B should be approximately 12 V.
