pressurized air the clutch pack 70 is composed of a plurality of discs interleaved with one another the friction discs 96 are splined to the clutch hub 92 and the steel discs 94 are splined to the housing 78 the clutch housing 78 is not splined to the output shaft 14 and can rotate freely the housing 78 is coupled to drive sprocket 86 which is also free to rotate about the output shaft 14 upon engagement of the clutch pack 70 torque from the output shaft 14 is transferred through the clutch hub 92 through the clutch pack 70 through the housing 78 through the drive sprocket 86 then through chain 88 through driven sprocket 90 and finally through secondary output shaft 84 it should be appreciated by those skilled in the art that the clutch pack 70 can be engaged by means other than the use of the electromagnetic coil 68 hydraulic fluid or pressurized air could also be used to actuate the clutch pack and produce the same result also incorporated in the transfer case are two hall effect sensors 52 a first hall effect sensor 52 is disposed in proximate sensing relationship with collar of the dog clutch 30 when it is in the one to one or direct drive position a second hall effect sensor 52 is in proximate sensing relationship to the dog clutch 30 when it is in the reduced speed position the hall effect sensors 52 directly locate the position of the dog clutch 30 which eliminates the need for detecting.
