This is the Injector Installer and Remover Kit made for use on the Caterpillar 3126B, C-7
& C-9. This is a direct replacement of the CAT 152-1057, 191-6077, 272-1149, and 274-9198The M10240 Injector Installer & Remover Kit is a comprehensive diesel engine service tool set designed to support removal and installation of fuel injectors on Caterpillar 3126B, C7, and C9 diesel engines. These engines are commonly found in medium- and heavy-duty applications including trucks, buses, construction equipment, and industrial machines. Proper injector service is essential to maintaining efficient fuel delivery, combustion performance, and emissions compliance.
Injector removal and installation must be done with precision and care. Improper techniques—such as using pry bars, oversized sockets, or makeshift tools—can damage injector bodies, bore sealing surfaces, and cylinder heads. The M10240 Kit provides engine-specific tooling that engages injector assemblies securely and applies controlled force for both extraction and installation. This results in clean removal, accurate seating, and minimal risk of component damage.
Built from high-strength, precision-machined steel, this professional-grade kit is ideal for diesel repair shops, fleet maintenance facilities, and engine rebuild operations that demand reliable, repeatable service results. Whether performing routine maintenance, top-end overhaul, or injector component replacement, the M10240 Kit helps ensure each injector is serviced with accuracy and confidence.

Why It Matters
Correct injector removal and installation are vital to engine performance. Misaligned or damaged injectors can lead to poor fuel atomization, compression loss, increased emissions, rough idle, and loss of power. The M10240 Injector Installer & Remover Kit allows technicians to handle injectors with precision and care while minimizing the potential for costly damage to expensive engine components. This leads to better long-term reliability, improved combustion performance, and reduced return-for-service issues.
