4. Setup

Before using the tool, ensure the work area is clean and well-lit. No specific assembly is required for this tool.

1. Ensure the PDE unit injector to be adjusted is accessible and clean.
2. Have the necessary vehicle service manual readily available for specific torque values and procedures.

5. Operating Instructions

This tool is used to accurately set the height of PDE unit injectors to 69.9 mm. Follow these steps carefully:

1. Prepare the Injector: Ensure the PDE unit injector is correctly installed in the cylinder head according to the Scania service manual.
2. Position the Tool: Place the HGV TOOLS measuring tool onto the PDE unit injector. The tool is designed to fit precisely over the injector, allowing for accurate measurement of its height.
3. Adjust Injector Height: Using the adjustment mechanism of the PDE injector (refer to the Scania service manual for specific adjustment points), carefully adjust the injector until the measuring tool indicates the correct height of 69.9 mm. The tool provides a fixed reference point for this measurement.
4. Verify Measurement: Double-check the measurement to ensure the injector is set to the specified 69.9 mm.
5. Secure Injector: Once the correct height is achieved, secure the injector according to the vehicle manufacturer's specifications, applying the correct torque values.
6. Remove Tool: Carefully remove the measuring tool from the injector.
