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
void any possible warranty or return privileges. If you do not fully understand modifications or changes that will be required to complete your conversion, we strongly recommend
that you contact our sales department for more information. This instruction sheet is only to be used for the assembly of Advance Adapter components. We recommend that a
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.
NOTE: The fine thread 1.5” stud threads into the lower bearing hole on the adapter. Prior to installation, the threads
should be coated in RTV silicone to prevent possible oil leaks in the future. Also supplied are two smaller set screws
to plug lower unused mounting holes. These should also have a small amount of RTV silicone applied to the threads
before installation.

At this point, check to make sure all studs are in their correct hole position for your application.
5. Next, install the supplied bearing spacer onto the output shaft.
6. Install the bearing retainer and supplied sealed bearing. For Dana 20 applications, the sealed bearing is followed
by a snap ring.
7. The bearing installation should then be followed by the six spline input gear, washer, and lock nut. Torque the lock
nut to 75 ft./lbs.
NOTE: For Dana 18 applications, the input gear will be installed after the case has been bolted to the adapter.
8. Before installing the second gasket, test fit the transfer case to the adapter. Check to see if all bolts line up and
are correct lengths. The stud length can be adjusting by hand or with an Allen wrench.
9. If everything checks out, install the adapter to the transfer case gasket with gasket sealer if so desired.
10. Finally, install the transfer case to the adapter using the supplied hardware. The best way to accomplish this is
to turn the transfer case output shaft (assuming it's in gear) while inserting the case onto the adapter and input gear.
Torque all nuts to approximately 35ft./lbs.
Transmission Mount:
1. The supplied rubber mounts sandwich between the top and bottom of the stock crossmember. Some trimming is
required to mount the supplied rubber mounts to the bottom of the adapter.
2. The passenger mount requires trimming when the transfer case is clocked to its furthest down position.
