CRR920C Diesel Common Rail Injector Stage 3 Measuring Tool

The CRR920C Diesel Common Rail Injector Stage 3 Measuring Tool is a high-precision calibration system designed for professional diesel repair workshops. Rebuilding a common rail injector requires more than just cleaning; it demands exact mechanical adjustments. The CRR920C is engineered to measure the critical internal shim gaps and component strokes that determine injector performance.

This comprehensive tool kit allows technicians to accurately measure the Armature Lift, Needle Lift, Residual Air Gap, and Solenoid Valve Spring Stroke. It is universally compatible with major injector brands, including Bosch, Denso,  Equipped with high-sensitivity digital micrometers and a complete set of mounting adapters, the CRR920C ensures that every injector is rebuilt to original factory specifications. By using this tool to verify the internal "Stage 3" parameters, you can eliminate knocking, black smoke, and starting issues caused by improper internal tolerances.

• High Precision Measurement: Features top-grade digital micrometers to detect deviations as small as microns, ensuring exact shimming and calibration.

• Universal Compatibility: Includes a wide range of specialized measuring seats and adapters, covering Bosch (110/120), Denso

• Essential for Rebuilding: Specifically targets the "Stage 3" repair process (internal mechanical stroke), which is crucial for restoring the correct fuel injection timing and quantity.

• User-Friendly Operation: Designed with an intuitive interface and distinct measuring fixtures, making it easy for technicians to switch between different injector types quickly.
