F698122 Force SEAL, PARTING LINE

Put a small amount of clean engine oil or glycerine on the lip of seal (4) and in the bores of the O-ring seals at assembly.(1) Distance bearing is installed below pipe surface ... 0.25 0.25 mm (.010 .010 in)(2) Diameter of shaft ... 15.80 0.03 mm (.622 .001 in) Bore in bearings ... 15.88 mm (.625 in)Bore in pipe for bearings ... 18.263 0.013 mm (.7190 .0005 in)(3) Valve assembly shown in the "run" (open) position. When the valve is closed a 0.08 mm (.003 in) feeler gauge must not fit between the valve and the bore in the pipe at any point.(4) Seal. Install the seal with the tip of the seal toward the outside as shown.(5) Diameter of shaft ... 9.60 0.03 mm (.378 .001 in) Bore in the bearing ... 9.80 0.03 mm (.386 .001 in) Adjust shaft as needed to change spring tension until hold-in current consumption (draw) is less than 2 amps at shutdown.(6) 108-2858 Torsion Spring: Free length ... 54.5 0.5 mm (2.15 .02 in)Outside diameter ... 30.36 0.5 mm (1.195 .020 in)(7) 3N7848 Spring: Length under test force ... 22.86 0.5 mm (.90 .02 in)Test force ... 4 N (1 lb)Free length after test ... 35.6 0.5 mm (1.40 .02 in)Outside diameter ... 18.8 0.5 mm (.74 .02 in)(8) Bracket assembly. Bracket assembly must be adjusted so valve assembly (3) is parallel to pipe bore within 2 degrees.(9) 4N3890 Solenoid: Voltage rating ... 24 or 32VCurrent consumption (draw): Pull-in windings ... 39.1A at 38.4VHold-in windings ... .58A at 38.4VPlunger travel ... 11.7 0.3 mm (.46 .01 in)Distance from plunger face to flange face: with solenoid energized* ... 9.6 0.5 mm (.38 .02 in)with plunger extended ... 21.28 0.13 mm (.838 .005 in)*The hold-in current consumption (draw) on engine must take less than 2 amps at shutdown.(10) Diode assembly. Diode assembly required to suppress the back EMF voltage spike generated when the solenoid is turned off.Electric Shutoff Groups
