AX-5 INSTRUCTIONS:
This kit is designed to adapt the Jeep AX-5, 5-speed transmission to the Jeep Dana 300 transfer case and also as a rotation
kit for the Dana 300 transfer case.
This kit will allow you four rotation angles for the Dana 300 and proper spline engagement with little or no modifications.
A special long splined input shaft must be installed on the front of your Dana 300, replacing the stock input. The transfer
case input assembly must be taken apart to install the new input shaft. To do this, remove the six Allen head bolts on the
front retainer. There are two pry grooves located on the stock retainer. Use two pry bars into these slots to remove this
aluminum retainer. When the retainer is removed, you will find the drive gear, input shaft, and bearing on this retainer
assembly. By removing the snap rings on this assembly, these items will need to be taken apart. Once the items are
disassembled, you will need to set aside the stock roller bearing. A new sealed roller bearing has been provided to isolate
the gear box fluids. Install the new Dana 300 input shaft and secure by using the stock snap rings. Once this assembly
is assembled, you will then need to reinstall this retainer assembly back into your Dana 300 transfer case.
The aluminum adapter plate must be rotated to line up the 6 counter sunk holes to the Dana 300. Use a gasket or RTV
blue silicone between these two components. Fasten the S.H.C.S. bolts with Loctite, securing the plate to the transfer
case.
Before bolting the two halves together, you MUST trial fit them together. Please
note that the majority of these installations will require the input retainer be
modified slightly. There is an allen type plug located on the back of the AX-5
transmission. A small amount of grinding is necessary to clear the plug. The
ground area measures approx. 1" long, and about 1/8" deep for sufficient
clearance. There may also be a small amount of grinding needed on the output
shaft. Please verify this when mocking the two together, and trim accordingly.
Once you decide on the rotation, install the six studs into the adapter ring (these
studs are a tight fit into the ring). Use a gasket or RTV blue silicone and fasten
the transfer case to the transmission adapter plate.
SPECIAL NOTE:
When rotating the Dana 300 to a higher
rotation, you may experience some
transfer case shifter interference. We
recommend that a twin stick shifter for
the Dana 300 be obtained to acquire
the necessary clearances.
