Information:
Oil Pressure Test at Solenoid Valve
Work carefully around an engine that is running. Engine parts that are hot, or parts that are moving, can cause personal injury.
Table 1
Tools Needed    
Part Number     Part Name     Quantity    
149-6111     Oil Pressure Test Kit     1    
Illustration 1 g00527135
(1) Pressure gauge (2) O-ring seals for the solenoid valve (3) Adapter (4) Test body for the control valve (5) Control valve adapter (6) Solenoid valve adapter
Attach pressure gauge (1) to solenoid valve adapter (6) .
Remove the solenoid valve and the three seals from the compression brake housing. Refer to Disassembly and Assembly, "Compression Brake - Disassemble" for more information.
Install three new seals (2). Place the smallest seal in the bottom of the bore for the solenoid. Install the other two seals on solenoid valve adapter (6) .
Illustration 2 g00521296
Typical example (7) Bore
Lubricate the seals with clean engine oil and install the adapter assembly in bore (7) for the solenoid valve. Hand tighten the adapter assembly and then tighten the adapter assembly for an additional 1/4 turn.
Start the engine. Ensure that the compression brake switch is in the OFF position.
Record the oil pressure reading.
Increase the engine speed by 400 rpm.
Repeat Steps 6 and 7 up to the rated engine rpm.
Stop the engine. Install the solenoid valve. Refer to Disassembly and Assembly, "Compression Brake - Assemble" for more information.Compare the oil pressure readings from the solenoid valve to the oil pressure readings from the control valve. Refer to Testing and Adjusting, "Control Valve (Compression Brake) - Test". If the oil pressure at the solenoid valve is higher than the oil pressure at the control valve, continue with Steps 10 through 15.
Start the engine.
Disconnect the wires from each solenoid valve except for the solenoid valve that is being tested in order to check each solenoid valve individually.
Illustration 3 g00521295
Typical example (8) Solenoid armature
Turn the compression brake switch to the ON position. Observe the movement of solenoid armature (8). The solenoid armature should snap down fully. Push down on the solenoid armature in order to verify that the solenoid is fully actuated.If the solenoid valve fully actuates, proceed to Step 14. Otherwise, continue to Step 13.
Check the voltage at the terminals on the solenoid valve. There should be at least ten volts at the terminals.Insufficient voltage at the terminals indicates that there are either poor connections in the circuit or that battery voltage is low. Verify proper battery voltage. Check the condition of the connections and clean the connections.Replace the solenoid valve if both of the following conditions exist:
The solenoid valve is receiving the correct voltage.
The solenoid valve does not actuate fully.
Look for excessive oil leakage from the bottom of the compression brake housing opposite the solenoid valve. While the solenoid valve is electrically actuated, leakage should be no more than two drops per second. Replace the solenoid valve if there is excessive leakage.Note: When the solenoid valve is deactivated, oil will dump from the solenoid valve. This is a normal condition that should not be confused with oil leakage while the solenoid valve is electrically actuated.
Repeat Steps 11 through 14 for each solenoid valve.
Work carefully around an engine that is running. Engine parts that are hot, or parts that are moving, can cause personal injury.
