SECTION 1- INTRODUCTION
NOTICE The TecBrakeEngine Brake is designed as a device for slowing a vehicle, not stopping it. It is to be used in conjunction with, but not a substitute for the vehicle’s service brakes. The service brakes must be in good operating condition and used to bring the vehicle to a complete stop.
Material Required The TecBrake kit includes all of the parts required to make an installation on the most common engineconfigurations. Prior to installation, determine the engine model to verify that the engine brake being installed is correct for the engine. The engine model number can be found on the option labels located on the valve cover or stamped on the cylinder block below the intake manifold. Also determine whether the engine is a DDECII or DDECIII. Depending on engine control, a different control group isrequired. Refer to the Application Chart, which list all engine model numbers on which the T765A and T760A engine brake may be installed.
