How
to ID Gear Drive Case
- If you have
7 bolts in the rear cover then you have
the gear driven unit.
If you have 5 bolts holding the rear cover
then you have the chain drive unit.
- Bolt
#7 is behind the drive shaft and can't be
seen in this picture.
Top
vs Forward Shift
In both
photos the transmission and transfer case
have been separated to show where one
ends and the other starts. It also helps
show the shift forks on the forward shift
setup. The left photo shows a top shifting
transfer case and transmission. Notice
the tcase shifter comes out of the top
of the tcase. The transmission has just
one shifter. Notice there are no forks
on the front of the tcase. The right photo
is a forward shift transfer case. Notice
the block off plate on top of the case.
This unit is shifted through two rails
that connect to the transmission. A forward
shift transmission like this one has two
shifters, one for the tranny and one for
the tcase. Click photos for larger image.
The block
off plate of a forward shift style tcase
can be seen from under the vehicle. From
under the truck on the driver side look
up at the transfer case to see the block
off plate.
