IDENTIFICATION
The identification tag is an aluminum tag attached
under one of the self-tapping case bolts (figure 1). The
tag provides the Borg-Warner part number, General
Motors part number, serial number, and the build date.
The information on the tag is necessary for servicing
information. If the tag is removed or becomes dislodged
during service operations, be sure to keep the identifi­
cation tag with the unit.
POWER FLOW
Torque is transmitted through the input shaft to the
planet carrier assembly. Torque flow continues through
the ring gear to the rear output shaft. Torque is trans­
mitted from the planet carrier assembly to the sun gear
shaft which is splined to the drive sprocket. The drive
gear is connected to the driven sprocket by the drive
chain. Torque continues through the driven sprocket to
the front output shaft flange. The viscous clutch pro­
vides the connection between the ring gear and the sun
gear shaft.
