Injector Calibration & Timing Tools

Detroit Diesel Injector Timing Tool (1.460)
Injector timing is crucial in Detroit Diesel’s two-stroke engines, and this Kent Moore 1.460 timing tool provides precise calibration to ensure the correct injector rack setting. Using this tool, technicians can accurately measure injector plunger height to achieve the ideal timing angle for each cylinder. Proper timing prevents pre-ignition, improves fuel economy, and protects engine components from excessive wear. This is an essential tool for anyone rebuilding or servicing Detroit Diesel injectors.

Fuel Delivery Components for Series 53 Engines

Detroit Diesel Fuel Line for Series 53
Fuel jumper lines play an important role in maintaining constant pressure between injectors. This precision-formed steel line is designed for the Detroit Diesel 353 Turbo and resists vibration and heat under continuous operation. Proper fuel line condition ensures no loss of pressure or leakage between cylinders, improving combustion consistency and engine reliability.

Detroit Diesel Fuel Connector
The fuel connector secures each jumper line to the injector body, maintaining a leak-free seal even under the elevated pressures of turbocharged operation. Diesel Pro Power’s connectors are manufactured from corrosion-resistant alloy for long-lasting performance, ensuring secure fuel transfer with minimal maintenance requirements.

Detroit Diesel Washer – Fuel Pipe Connector
These washers provide critical sealing between connectors and fuel lines, preventing fuel seepage. A worn or deformed washer can result in minor leaks that reduce fuel efficiency or create fire hazards, making periodic replacement essential. Each washer is precision-machined to OEM tolerance for the Detroit Diesel Series 53.

Specialized Installation Tools

Socket for Injector Fuel Lines – Series 53, 71 & 92[
This heavy-duty socket tool is designed specifically to install and remove injector fuel lines on Detroit Diesel two-stroke engines. The unique design prevents rounding or distortion of fittings, ensuring secure torque application and reducing the risk of leaks. Built for professional and fleet mechanics, this tool is essential for maintaining injector line integrity during engine rebuilds.

Injector Maintenance & Service Kits

Detroit Diesel Service Kit for Injector
This comprehensive injector service kit includes seals, springs, and small hardware items necessary to rebuild or refresh injectors during scheduled maintenance. Designed for field and workshop applications, it allows technicians to restore injector performance without full replacement, saving time and cost.

Detroit Diesel Injector Bracket
This bracket anchors the injector body to the cylinder head, ensuring alignment and stability under high-pressure operation. A damaged or warped bracket can cause misalignment, fuel leaks, or even injector tip damage. Diesel Pro Power’s brackets are built from durable, heat-treated alloy for long service life.

Detroit Diesel Washer for Engine Injector
Engine washers maintain proper clamping force for the injector assembly. Each washer is precision-ground to distribute pressure evenly and maintain tight sealing, preventing injector movement during vibration.
