4. Setup

Before attempting to remove an injector, ensure the engine is cool and all necessary safety precautions are in place. Identify the type of injector (Denso, Siemens, Bosch, Delphi) and its specific connection type (M12 or M14) to select the correct connector from the kit.

1. Prepare the Injector: Clean the area around the injector to prevent debris from entering the fuel system. Ensure the electrical part of the injector is not obstructed.
2. Select Connector: Choose either the M12 or M14 connector based on the injector's threading. If the original coupling cannot be removed, these connectors provide an alternative attachment point.
3. Assemble the Puller:
   • Thread the selected connector onto the top of the injector.
   • Attach the articulator with the foam handle to the connector.
   • Slide the 1.5 kg (3.3 lbs) slide hammer onto the slide hammer shaft.
   • Connect the slide hammer shaft to the articulator.
   • If needed, use the provided spacers to adjust the length or leverage.

5. Operating Instructions

The injector can be removed using two primary methods: rotation with the handle or axial extraction with the slide hammer.

5.1. Method 1: Rotating with the Handle

1. Ensure the puller assembly is securely attached to the injector.
2. Grip the foam handle of the articulator firmly.
3. Apply steady, rotational force to the handle, attempting to twist the injector free from its seating. This method is often effective for injectors that are not severely seized.
4. Once the injector begins to loosen, continue rotating and gently pulling until it is fully extracted.

5.2. Method 2: Axial Extraction with Slide Hammer

1. With the slide hammer assembly attached to the injector, hold the slide hammer shaft firmly.
2. Slide the 1.5 kg (3.3 lbs) hammer forcefully towards the handle, away from the injector. The impact of the hammer against the stop will create an upward pulling force on the injector.
3. Repeat this action, applying consistent and controlled impacts, until the injector begins to move.
4. Continue the axial extraction process until the injector is completely removed from its bore.
5. Caution: Avoid excessive force that could damage the injector or surrounding engine components. If the injector is extremely stubborn, apply penetrating oil and allow it to soak before attempting removal again.

6. Maintenance

Proper maintenance ensures the longevity and reliable performance of your CTA Tools 7808 Injector Puller Kit.

• Cleaning: After each use, clean all components with a clean cloth to remove any fuel, oil, or debris.
• Lubrication: Lightly lubricate threaded parts and the slide hammer shaft with a general-purpose oil to prevent corrosion and ensure smooth operation.
• Storage: Store the kit in its original case in a dry, clean environment to protect it from moisture and damage.
• Inspection: Periodically inspect all components for signs of wear, damage, or corrosion. Replace any damaged parts immediately.
