Atlas 4sp Transfer Case



Atlas 4Sp Transfer Case Shift Selector Fork
This little shift selector fork enables shifting between the reduction housing gearsets in the planetary housing. Notice how the two round recessed reliefs are separated by a groove where a hardened pin will sit. This pin becomes the wear surface for the shift selector detent. This little detail helps ensure the 4SP will always shift easily and properly.		 Atlas 4Sp Transfer Case Planetary Housing
Here is the planetary housing fully loaded with all the gearing that makes a standard Atlas II an Atlas 4SP. Notice the little lubrication galley that provides oil to the planetary housing (arrow). As oil is slung up by the internal gears in the main part of the case, this little gutter directs oil to the planetary housing.		 Atlas 4Sp Transfer Case Selector Clog
Here you can see how the planetary shift fork fits on the selector cog before the planetary housing was installed.
Atlas 4Sp Transfer Case Plastic Removable Caps
Once the planetary housing is bolted to the case, all that's left to do is bench-test the unit and seal it up for shipping. Little plastic removable caps are used to ensure nothing can contaminate the case during shipment.
