JEEP INSTRUCTION MANUAL
Before assembly of the transmission with the new
main shaft, you must verify that the correct shaft is
being used. Your spline count on the shaft must be
23-splines. Advance Adapters also manufactures a
27-spline shaft that will not be compatible with your
NP231 transfer case.
The T18 shafts had two main shaft
designs. The difference between the
shafts is the hub between the sec-
ond and third gears (both designs are
interchangeable into the transmis-
sion). Some shafts have a snap ring
and washer and others have the
spacer as part of the shaft. Most of
our shafts have the hub as part of
the main shaft. If you have the snap
ring design, just omit the washer and
snap ring when loading the gears on
the new main shaft.
