Usage:
3306 Truck Engines
Description of Change: A new fuel pump bonnet seal is available on the 3306 Truck Engines. The former fuel pump bonnet seal could lose its sealing capability when exposed to above normal temperatures (heat) for extended periods of time. The high temperatures can cause the seal to lose its shape and become brittle. The new seal material has a greater resistance to heat and thus improves the reliability and life of the seal.
Location of new 114-8718 Seal (fuel pump bonnet) on 3306 Truck Engines. This illustration is intended to depict the location of the 114-8718 Seal only. Some of the other fuel injection pump components may not currently look like those in the illustration.
Adaptable To: The new 114-8718 Seal is a direct replacement for the former 6V-6228, 7E-4846, and 3D-2992 Seals. The only difference between the new 114-8718 Seal and the former 6V-6228 Seal is the blue teflon coating on the new seal. The blue teflon coating provides lubrication during assembly that helps prevent cutting the seal.
