This injector brush kit is used to clean the injector bore and fuel
gallery. Failure to properly clean the injector bore will prevent new
cups from seating properly. This set is for use on the following
engines: 1994-2003 Ford 7.3, 1994-2014 Navistar T444E, Navistar DT466,
Maxxforce DT/ 9 / 10 / N9 / N10, 1998-2006 CAT 3126, C7, C9The ATC-50137 Diesel Injector Bore Brush Kit is a comprehensive service solution engineered for cleaning injector bores and sealing surfaces on a wide range of heavy-duty diesel engines, including Caterpillar, Navistar, and MaxxForce platforms. Injector bore cleanliness is a key factor in achieving proper sealing, combustion efficiency, and long-term fuel system reliability. Carbon, soot, corrosion, and old gasket residue left in injector bores can lead to poor injector seating, fuel leakage, misfires, and reduced performance.
This kit includes a selection of precision-sized bore brushes with heavy-duty copper bristles designed to match the injector bore diameters common to Cat, Navistar, and MaxxForce engines. Copper bristles provide effective debris removal while being soft enough to clean without scoring or damaging precision machined surfaces inside cylinder heads. The robust kit setup enables technicians to prepare injector bores quickly and consistently before reinstalling injectors or performing top-end service.
Ideal for diesel engine repair shops, fleet maintenance facilities, and professional rebuild operations, the ATC-50137 Diesel Injector Bore Brush Kit helps deliver professional-grade results, reduces rework due to improper sealing surfaces, and supports optimal fuel system performance across multiple OEM engines.

Why It Matters
Injector bores must be clean and free of debris to ensure injectors seat properly, avoid leaks, and maintain proper fuel combustion. Contaminated or corroded bores can negatively impact engine performance, fuel efficiency, and emissions control. The ATC-50137 Diesel Injector Bore Brush Kit provides technicians with the right tools to prepare injector bores thoroughly—reducing service issues and promoting long-term engine reliability.
