For diesel parts distributors, heavy equipment repair shops and fleet operators sourcing validated Caterpillar fuel system components, the 236-0962 is an industrial-grade basic fuel injector purpose-built for compatible CAT C7, C-7, C9 and C-9 diesel engine platforms. Its primary OE part number is 236-0962, which also appears as 2360962 in parts database indexing, while 10R-7224 (or 10R7224) is listed as the official reman injector cross-reference for equivalent replacement searches.

This injector fits a wide portfolio of Caterpillar heavy equipment across construction, mining, forestry and industrial power sectors, covering 330C-series excavators, 12H motor graders, 973C track loaders, 627G/637G/637D wheel scrapers, TK-series forestry equipment, D6R II tractors and Challenger/MT/MTC-series work units. Caterpillar specifies that fitment depends on original equipment specifications and the machine’s current configuration; modified equipment requires dealer verification, and purchasers must confirm part number, engine serial number, machine model and injector code before installation.

As a critical fuel system component, it receives diesel fuel from the engine fuel supply circuit, meters precise fuel quantities and delivers high-pressure atomized fuel into the combustion chamber at the exact required timing and spray pattern. It coordinates with the engine’s fuel supply system and control strategy to support stable idle, responsive throttle performance, controlled exhaust smoke and balanced power output across all cylinders.
