CRM900/CRM920 Common Rail Injector Measurement and Repair Stage 3 Tool Kit
The CRM900/CRM920 is a professional-grade precision measurement system designed for the "Stage 3" repair and calibration of common rail injectors[cite: 54]. This comprehensive kit enables technicians to accurately measure critical internal dimensions, including armature lift, needle valve lift, and electromagnetic air clearance[cite: 57, 60, 61].
Equipped with a smart controller and high-precision dial gauges, the system provides real-time data and automatically calculates the required thickness for adjustment gaskets if measurements exceed standard ranges[cite: 58, 59]. It is an essential solution for ensuring the performance and longevity of fuel injectors through precise electromagnetic and mechanical calibration[cite: 57, 83].






High Precision Measurement: Equipped with a 0.001mm resolution dial gauge and specialized measuring heads for extreme accuracy[cite: 58, 60].
Intelligent Diagnosis: The system automatically obtains measurement results and prompts the exact adjustment amount for gaskets if results are out of range[cite: 59, 73, 82].
Comprehensive Functionality: Supports multiple testing methods, including both electromagnetic drive and manual pressing methods for armature lift[cite: 57, 83].
Versatile Application: Includes a wide variety of injector fixtures and apertures to accommodate different types of fuel injectors[cite: 57, 60].
Data Management: Features a "Record" function on the operation interface to save intermediate values for seamless repair workflows[cite: 66].
User-Friendly Interface: Large display screen with clear functional icons for Measure Kit, Injector Driver, and Video tutorials[cite: 54].
