Orion Instructions
:
The following instructions cover the disassembly of your stock transfer case along with the assembly of the Orion
transfer case. Listed throughout these instructions, we refer to various item numbers. These item numbers represent
components on one of the three schematics shown at the end of these instructions. The item numbers listed represent
the following: "C" is the case schematic, "G" is the gear schematic, and "S" is the shifter schematic. These drawings
also have an index page that corresponds the common terminology of these components.
Drain gear lubricants from transmission and transfer case.
Remove the parking brake drum retaining nut.
On 1963 to 1973 10-spline T/C, or as we'll term 3 Speeds - Reference item #’s C9, C10, C11. Retain item C9
On 1974 to 1980 16-spline T/C, or as we'll term 4 Speeds - Reference item #’s C6, C7, C8. Retain items C6, C7
This should be done while still in the vehicle after
the front and rear drive shafts are removed. You
will be able to slide the brake drum off and then the
brake plate assembly. This will keep you from
having to remove the brake cable from the brake
plate. Once this is achieved, simply unscrew the
speedometer cable from the speedometer shaft
sleeve.
Stock Transmissions:
We strongly recommend that stock 3 and 4 speed transmission combinations be removed completely from the vehicle.
In order to remove the transfer case from your transmission, please refer to a manual that covers your application.
Advance Adapters (spud shaft style) transfer case adapter systems:
If you are removing a transfer case from a transmission that is using our conversion adapter, it is possible to only remove
the transfer case. It will be up to your own discretion to unbolt either the adapter housing from the transmission or the
transfer case from the adapter housing. In either instance, our conversion adapters require the transfer case to slide
rearwards only a few inches to disengage the transmission output shaft from our adapter spud shaft.
