YOKE AS 1746997 - Caterpillar

(1) Ether cylinder assembly. Position 20 degrees from vertical.(2) Clamp assembly. Position clamp assembly 178 mm (7.01 in) vertically above ether valve assembly mounting holes.(3) Ether valve assembly. With cylinder assembly (1) installed, the valve assembly provides 2.25 cc (.14 cu in) of ether through the steel tube to atomizer assembly (8) in the air inlet manifold system each time control panel switch (4) is pressed for three seconds, then released.Locate as close to the engine inlet manifold as possible (do not mount on engine).Do not mount in a location that subjects valve assembly and cylinder assembly (1) to temperatures greater than 93.3°C (200°F).Install valve assembly so cylinder assembly (1) can be installed in a vertical position as shown.(4) Control panel switch. Install switch close to operator's starting station. Switch requires clearance hole for 5/8inch diameter thread, and 38 mm (1.50 in) depth behind control panel or mounting bracket.(5) Ether valve connector.
Location For Ether Atomizer Assembly And Temperature Switch Assembly.
(6) Temperature switch assembly. (8) Ether atomizer assembly. (9) Temperature regulator housing. (10) Cylinder head. (11) Inlet manifold.(6) Temperature switch assembly. The temperature switch will not allow starting fluid to reach the atomizer if the engine temperature is above 38°C (100°F). Final installation tighten to 1.2 N m (11 lb in).Remove 3/8 inch pipe plug from temperature regulator housing (9) and install the temperature switch.(7) Flexible tube assembly. Assemble 3.18 mm (.125 in) O.D. steel tubing between ether valve assembly (3) and ether atomizer assembly (8). Use the flexible tube assembly as a flexible connection between the two lines. The use of any additional length of tubing is not recommended. No electric wires are to be clamped to the ether line.(8) Ether atomizer assembly. Remove 1/2 inch pipe plug from inlet manifold (11) and install atomizer assembly. Before atomizer assembly is tightened, turn identification mark to face front or rear of the engine.
