INSTRUCTIONS:

This kit is designed to adapt the Jeep NV3550 5-speed 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 input shaft and 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.

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.

ASSEMBLY NOTE: Some NV3550 have a

.100" stickout on the output shaft & require you
to trim the output shaft flush with the rear of the
transmission

The steel 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.

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.

Things to consider during the installation are floorboard clearances and transfer case shifter handle location & clearance.
Since we have rotated the Dana 300 up higher than the stock rotation, the shifter handle may need to be bent for proper
fit. The other option is an aftermarket twin stick shifter for the Dana 300.

Due to the rotation of the transfer case you should add some additional oil to the transfer case to maintain proper oiling.

SPECIAL NOTE: The components packaged in this kit have been assembled and machined for specific type of conversions. Modifications to any of the components will

service manual pertaining to your vehicle be obtained for specific torque values, wiring diagrams and other related equipment. These manuals are normally available at automotive
dealerships and parts stores.

NV3550 5-SPEED TO DANA 300 KIT

NOTE: Some transmissions have a weep hole or slot (as seen in picture to right).

When using this kit it is important that this hole/slot is sealed using RTV
Blue Silicone. This will prevent fluid leaking from the adapter.

The location may vary depending on the year and model of transmission,
some transmissions have a weep hole that begins on the inside of the
casting and continues down through the bottom of the mounting foot.

RTV Blue silicone shut the oil slot

completely to prevent leakage.
