The M50136 Navistar DT Injector Sleeve Brush Set (ZTSE 4304) is a specialized diesel engine maintenance kit engineered to clean injector sleeve bores and sealing surfaces on Navistar DT series diesel engines. Injector sleeves must seat precisely in the cylinder head to ensure proper combustion chamber sealing and prevent coolant or combustion gas cross-leakage. Over time, carbon buildup, deposits, corrosion, and old gasket material can accumulate in the injector bore and around the sleeve sealing surface, jeopardizing seal integrity and engine performance.

This brush set includes multiple precision-sized, heavy-duty stainless brushes designed to match common DT series injector sleeve diameters and contours. stainless brushes are ideal for abrasive residue removal while being soft enough to avoid scoring or damaging precision-machined bores or sealing surfaces—critical when preparing injector sleeves for service or reinstallation.

The M50136 set is a versatile diagnostic and preparation tool for professional technicians working in diesel repair shops, fleet maintenance facilities, and rebuild operations, helping ensure injector sleeves are mounted on clean, debris-free surfaces that promote dependable sealing and optimized engine performance.


Key Features & Benefits

  • Application-specific design: Tailored for Navistar DT series injector sleeve bores

  • Complete brush set: Multiple brush sizes included for proper cleaning of injector sleeve surfaces

  • stainless brushes construction: Powerful debris removal without bore surface damage

  • Improves sealing integrity: Prepares surfaces for secure injector sleeve seating

  • Professional grade durability: Built for repeat shop and field use

  • Enhances service quality: Reduces risk of leaks, misfires, and combustion inefficiency


Typical Applications

  • Cleaning injector sleeve bores during sleeve removal and reinstallation

  • Prepping cylinder head sealing surfaces prior to injector service

  • Diesel engine top-end maintenance, rebuilds, and reseals

  • Fleet and heavy-duty diesel maintenance environments

  • Navistar DT engine servicing including pressure control and combustion system work


Why It Matters

Injector sleeve seating surfaces must be thoroughly cleaned and free of deposits to ensure proper sealing and combustion performance. Residue inside the bore can lead to coolant intrusion, combustion gas bypass, injector misalignment, or early failure, all of which degrade engine reliability and lifespan. The M50136 Navistar DT Injector Sleeve Brush Set (ZTSE 4304) enables technicians to prepare injector bores confidently, improving seal integrity and reducing the likelihood of service-related issues.
