Note: Apply a small amount of clean engine oil or glycerin onto the lip of seal (7). Also, apply a small amount of clean engine oil or glycerin into the bores for the O-ring seals at assembly. (1) Diode assemblyNote: Diode assembly (1) is used to suppress voltage spikes that are generated when the solenoid is turned off. (2) 4N-3890 Solenoid Voltage rating ... 24 or 32 VCurrent consumption Pull-in windings at 38.4 Volts ... 39.1 Amp Hold-in windings at 38.4 Volts ... 0.58 AmpPlunger travel ... 11.7 0.3 mm (0.46 0.01 inch)The distance from the plunger face to the flange face The distance after the solenoid has been energized. ... 9.6 0.5 mm (0.38 0.02 inch) The distance after the solenoid has been extended. ... 21.28 0.13 mm (0.838 0.005 inch)Note: The hold in current consumption (draw) on the engine must take less than 2 amperes at shutdown. (3) The bracket assembly must be adjusted so that the valve assembly (9) is parallel to the pipe bore within 2 degrees. (4) 3N-7848 Spring Length under test force ... 22.86 0.50 mm (0.900 0.020 inch) Test force ... 4 N m (35 lb in) Outside diameter ... 18.8 0.5 mm (0.74 0.02 inch) (5) Diameter of shaft ... 9.60 0.03 mm (0.378 0.001 inch)Bore in the bearing ... 9.80 0.03 mm (0.386 0.001 inch)Note: Adjust the shaft in order to change the spring tension until the hold in current consumption (draw) is less than 2 amperes at shutdown. (6) 108-2858 Spring Free length ... 54.5 0.5 mm (2.15 0.02 inch) Outside diameter ... 30.36 0.50 mm (1.195 0.020 inch) (7) SealInstall the seal with the tip of the seal toward the outside, as shown. (8) Diameter of the shaft ... 15.80 0.03 mm (0.622 0.001 inch)Bore in the bearings ... 15.88 mm (0.625 inch)The bore in the elbow for the bearings ... 18.263 0.013 mm (0.7190 0.0005 inch) (9) The valve assembly is shown in the run position. When the valve is closed, a 0.08 mm (0.003 inch) feeler gauge must not fit between the valve and the bore in the pipe at any point. (10) Bearing depth ... 0.25 0.25 mm (0.010 0.010 inch) (11) Air Inlet Elbow
