New repair tool to be released 7/1/20!

- Posted on 06/22/2020

Tool Kit C15-3055, C15 injector reseating tool

Designed to ensure a quality repair when replacing Fuel Injectors in C15, C16, C18 and other Cat engines.

Cat engines sometimes develop a miss/flutter under load, shortly after installation of injectors. The reason for this is due to damage to the injector sealing surface in the Cylinder Head. Over time compression erodes the sealing surface allowing compression to bypass the injector seat causing aeration of the fuel. This problem can be confirmed by inspecting the injector for damaged oring and carbon tracking on the nozzle nut.

How the tools Work. There is a common miss conception that the injector seals against the Coolant Cup. The actual sealing surface is below the cup and is part of the Cylinder Head casting, this is not replaceable. These tools grind the Cylinder Head to repair the erosion that has occurred over the years to the sealing surface. Allowing the injector to seal the cylinder, keeping the combustion event where it belongs! Preventing warranty work. *

Save hours of work and $$$$, by using this tool kit to effortlessly repair damage to the injector sealing seat, with Tool Kit C15-3055 and a cordless drill, without removing the head, or Coolant Cup. *

Tool Kit C15-3055, C15 injector reseating tool is now available.

You can save $$$$, with the first use, and fix it right the first time. Preventing warranty work! *

Do not just replace, repair the problem and keep the engine running strong into the future!

*Unfortunately, there are cases where the damage is too severe for the Tool Kit to work properly. In these instances, replacing with a New or Aftermarket cylinder head is the best option.

Site Input

- Posted on 12/19/2014

Diesel Controls goal for this Injector Reference Site is to allow our customers the ability to research Injectors for the current Reman number, their cost and core charge, saving time and money.  It currently does NOT show availability.  This is something we are willing to add in the future when site usage justifies it.

Please let us know via the Contact Page of any known errors or Injector that is not on the site and we will either correct it or add it.

Thank you!

The rate of injection has tripled.

Did you know in today’s world of fuel injection, there has been a revolutionary change in diesel injectors?

The rate of injection has tripled. 

Once, injection rates were 5,000 to 10,000 lbs. 

Today, they are 40,000 to 50,000 lbs. 

DCI has met this challenge to meet today’s demand. With state of the art testing equipment and procedures, we are leaders in our field and our quality is second to none!
