HUB 3793897 - Caterpillar

Installation Procedure
(1) Put 5P2948 Connector (1) in ether valve (2). Install ether valve (2) in a good location, as follows: A. Install in a vertical position that is within the angle limit shown.B. As near the engine manifold as possible, but not on the engine.C. Do not install the ether valve in a location where the temperature is more than 93°C (200°F).(2) Install 7N2059 Clamp (3) directly above ether valve (2) according to the dimension shown. According to the ether starting air group that is to be installed, the part number of the atomizer will be either 6N7672 or 6N9995, and will look like item (9) in one of the above illustrations. When either atomizer is installed on an engine, the arrow [(F) or (G)] must be put in a specific position for each engine model. This instruction gives the correct position of the arrow for all engines.It is necessary to remove a 1/4" pipe plug from the air inlet system of the engine to install an atomizer (9). A 6N5899 Temperature Switch must also be installed, after a 3/8" pipe plug is removed from the cylinder head. See the information that follows for the location of the plugs to remove for installation of the temperature switch and an atomizer (9).3406 Turbocharged - Industrial, Marine, Marine Auxiliary, Truck
