caterpillar 3406 Truck Engine Brake Installations manual. Identify the engine model. The P-36 Engine Brake is designed for 3406 applications. Examine the valve cover. An identification tag is attached to the valve cover showing all the necessary information. NOTE 1: Early 3406 Engines prior to Ser.# 92U17820 require special fuel lines and may require a special turbo to manifold crossover pipe if equipped with a low mount turbo. These items are available through Caterpillar Distributors. NOTE 2: The P-36 kit is packaged as a basic kit without most wiring and switch components. An electrical group must be ordered separately and will have the items necessary for the specific application. i.e. Mechanical, PEEC II or PEEC III.The model P-36 uses a unique distribution system that allows a free flow of oil between the master and the slave pistons. (All drillings between master and slave radiate 360°(around the centre of the brake housing to a distributor body). This free flow of oil means there is less restriction to the opening and closing of the engine exhaust valves during engine brake operation. This translates into a more precise engine exhaust valve operation and less tendency to float, particularly at higher RPM’s, timing and full stroke are important: the exhaust valves are operated by the engine brake at a rate of 17.5 times per second and open only .070. The result is higher turbo pressure, yielding higher braking power. Moreover, with the exceptionally long stroke of the master piston (.400 on the Cat as opposed to .140 on the Cummins) special care must be taken to align the housings with the rocker arm adjusting screws and prevent distortion of the housing that the Cummins units are not subject to. Therefore, a number of mounting changes have been made over conventional design to ensure long life and minimum wear.
