The ATC J47391 Injector Puller is a heavy-duty, precision service tool engineered for the safe removal of fuel injectors on Detroit Diesel DD13, DD15, and DD16 engines. Designed as a direct functional equivalent to the OEM injector puller, this tool provides the controlled pulling force required to extract injectors that may be seized by carbon buildup, heat cycling, or long service intervals—without damaging the injector body or cylinder head bore.
Modern DD-series injectors are installed with tight tolerances and are exposed to extreme combustion heat. Attempting removal without a dedicated puller can result in broken injectors, damaged injector bores, fuel leaks, or costly cylinder head repairs. The ATC J47391 engages the injector correctly and applies straight, even force to remove it cleanly, supporting professional, OEM-level service outcomes.
Built for durability and repeat use, this injector puller is ideal for diesel repair shops, dealership service departments, fleet maintenance facilities, and engine rebuild operations working on Detroit Diesel HDE platforms.
