Each component is heat-treated alloy steel with hardened surfaces for long service life. The fixed clamping positioning device aligns the injector body, while the L-shaped bracket with toggle clamps delivers even clamping force to disassemble the solenoid nut, valve group, and nozzle without damaging the precision-machined mating surfaces. The hex wrenches (3/4 etc.) straighten the solenoid seat, and the threaded studs provide controlled axial force during assembly.

Workshop-tested worldwide, this repair kit saves mining truck operators and ship owners the cost of replacing a QSK-series XPI injector ($3,500–8,000 USD per injector) by enabling bench overhaul with original-spec clamping and re-calibration. Wooden crate export packing. CE certified. One-year warranty on parts.
