M10224 Caterpillar Injector Sleeve Installer – C-15 Engine

The M10224 Injector Sleeve Installer is a precision diesel engine service tool engineered to professionally install injector sleeves in Caterpillar C-15 engines. Injector sleeves provide the critical sealing interface between the fuel injector and the cylinder head, ensuring proper combustion sealing, preventing coolant intrusion, and maintaining engine performance. The M10224 delivers controlled, even press-fit force to seat sleeves squarely and at the correct depth—helping ensure reliable sealing and long-term engine durability.

Improper installation using socket ends, hammers, or makeshift drivers can easily distort the sleeve, damage the cylinder head bore, or compromise sealing surfaces. The M10224 eliminates these issues with a tool specifically sized to match Caterpillar C-15 injector bore geometry, providing even force distribution and reducing risk of surface scoring or misalignment during installation.

Crafted from high-strength, precision-machined steel, the M10224 is built for heavy-duty shop environments. It is ideal for use in diesel repair shops, fleet maintenance facilities, and professional engine rebuilding operations where accuracy and consistent results are essential.
