( 1 ) You can also use 6V-6067 Calibration Fluid .Note: See Special Instruction, SEHS7292, "Use of 5P-4150 Fuel Nozzle Tester 8S-2245 Kit" for more information.
Do not use dirty test fluids when you test fuel injection nozzles. Also, do not test fuel injection nozzles unless you have the correct service tools.The use of dirty test fluids and the use of incorrect service tools will result in damage to fuel injection nozzles.
Caterpillar Inc. recommends the use of Calibration Fluid (SAE J967) for testing the fuel injection nozzles. The temperature of the test fluid needs to be from 18° to 24°C (64° to 75°F).

Extra Valve (12) Gauge protector valve must be in the OPEN position at all times.Do not disassemble the fuel injection nozzle for cleaning or for adjustment. Use the following tests to determine if the nozzle's performance is acceptable:
"Valve Opening Pressure Test"
"Flush the Nozzle"
"Tip Leakage Test"
"Orifice Restriction Test"
"Leakage Test for Air Purge Screw"These tests follow immediately.Performance Tests for the Fuel System

Remove carbon dam (14) with needle nose pliers.
Do not use a steel brush or wire wheel to clean the nozzle body or the nozzle tip. Use of these tools can cause a small reduction of orifice size, and this will cause a large reduction in engine horsepower. Too much use of a wire brush will also remove the coating that is on the fuel injection nozzle for protection.
Remove seal (15) from the nozzle.
Clean the groove for carbon dam's seal.
Clean the body of the nozzle below with a 8S-2258 Cleaning Brush (16).
Carefully remove the carbon, but avoid damage to the body of the fuel injection nozzle with the brush.Note: A change of the color in the area below the groove is normal. This does not affect the body of the fuel injection nozzle.
