️ Setting Injector Timing Height Using the OBC Method on a Cummins KTA19 | DIESELPRO.COM

In this video, Dion from Imperial Diesel Service, LLC—a trusted Diesel Pro Power customer—demonstrates how to set injector timing height on a Cummins KTA19 engine using the OBC (Outer Base Circle) method. This procedure is a critical part of any top-end service or full engine overhaul, especially on high-performance engines operating in marine or industrial environments.

The Cummins KTA19 is a turbocharged, aftercooled 19-liter engine used across marine, power generation, and heavy-duty industrial sectors. Precise injector timing is essential for proper fuel delivery, efficient combustion, and long-term engine reliability. In this video, Dion shows how to set injector timing using the Outer Base Circle method, which involves measuring the injector plunger height when the cam lobe is at its lowest point.

This technique ensures that injectors are neither over-fueling nor under-fueling the cylinders, which could otherwise lead to rough operation, high exhaust temps, or incomplete combustion.
