The BOSCH CRIN 4.0 4-Pin Injector Disassembly and Test Kit is a comprehensive professional solution specifically engineered for the latest generation of heavy-duty common rail injectors. Unlike standard 2-pin injectors, the CRIN 4.0 (4-pin) system requires specialized fixtures and sockets for safe disassembly and precise internal measurement. This kit provides technicians with all the necessary tools to open, repair, and reassemble the injector without damaging the sensitive 4-pin solenoid valve or the high-precision internal components.






Targeted Design: Exclusively for Bosch CRIN 4.0 4-pin series used in MAN, Mercedes-Benz, and Cummins engines.
Safe Disassembly: Specialized sockets prevent damage to the unique 4-pin electrical connector during high-torque operations.
Precision Measurement: Includes tools to check and calibrate internal stroke and valve clearances essential for CRIN 4.0 performance.
Industrial Grade Quality: Made from hardened chrome-vanadium steel with anti-corrosion coating for long-term workshop use.
High Efficiency: Reduces repair time and minimizes the risk of component failure during the reassembly process.
Comprehensive Set: Covers nozzle removal, solenoid valve nut loosening, and internal seal replacement.
