ENGINE LUBRICATION SYSTEM DESCRIPTION - HYDRAULIC CIRCUIT

Overview

The lubrication method is a pressurized circulation type and it employs the full-flow filtering system. In the full-flow filtering system, all the oil supplied to the engine by the oil pump normally passes through the oil filter. It has excellent cleaning action.

TESTING

ENGINE OIL PRESSURE SWITCH TEST

Test

1. Oil Pressure Switch - Test

1. Disconnect the connector (A)
2. Check for continuity between the oil pressure switch terminal (B) and the engine (ground). There should be continuity with the engine stopped. There should be no continuity with the engine running
3. Connect the connector.

ENGINE OIL PRESSURE TEST

Special Tools Required

Oil Pressure Gauge Attachment 07406-0030000

Oil Pressure Gauge 07506-3000001

If the low oil pressure indicator stays on with the engine running, check the engine oil level. If the oil level is correct:

1. Oil Pressure Switch - Remove

2. Engine Oil Pressure - Test

1. Install the oil pressure gauge attachment and the oil pressure gauge
2. Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem before continuing
3. Allow the engine to reach operating temperature (fan comes on at least twice). The pressure should be:

Engine Oil Temperature: 176 ºF (80 ºC)

At Idle: 106 kPa (1.08 kgf/cm2, 15.4 psi) min.
At 2, 000 RPM: 373 kPa (3.80 kgf/cm2, 54.0 psi) min.

4. If the oil pressure is out of specifications, inspect these items:
   • Oil filter blocked or plugged.
   • Oil strainer blocked or plugged.

3. Oil Pressure Gauge Attachment and Oil Pressure Gauge - Remove

4. All Removed Parts - Install

1. Install the parts in the reverse order of removal.
