WARNING: To avoid serious personal injury,
possible death, or damage to the engine or
vehicle, read all safety instructions in the "Safety
Information" section of this manual.
1. See "DT 466 Performance Specifications" –
Appendix A (page 595) or "DT 570 and HT 570
Performance Specifications" – Appendix B (page
619) and Section 7 for specifications, operational
voltages, and values.
Form.
2. Make a test hose that will connect the ICP system
test adapter to the gauge bar or equivalent gauge.
3. Connect test hose to ICP adapter.
4. Remove the EOT sensor from the front cover. Oil
will spill out. Catch oil in container. Quickly
install ICP system adapter and test hose
assembly. Position hose so oil will not drain
out. If oil does not spill out of the EOT port, oil
supply is the problem.
WARNING: To avoid serious personal injury,
possible death, or damage to the engine or vehicle
– comply with the following:
When routing test line, do not crimp the line, run
the line too close to moving parts, or let the line
touch hot engine surfaces.
5. Connect test hose to gauge bar (0-160 psi gauge)
or equivalent gauge.
6. Crank engine for 20 seconds and monitor EOP.
7. Record pressure on Diagnostic Form.
• If oil pressure is below specification, diagnose
lube oil pressure system, see Section 4 –
"Engine Symptoms Diagnostics" (page 101).
• If oil pressure is at specification, remove test
hose and gauge bar. Quickly remove ICP
system adapter and test hose assembly. Oil
will spill out. Catch oil in container and
install EOT sensor. Follow the procedure in
Engine Service Manual.
