Advance Adapters 403300 - Manual (Page 4)

3. Check that the existing hole in the floor will be large enough for the new shifters. If additional room is needed, cut/
grind the hole in the floor to the correct shape. Be careful not to cut the hole too large so that the shift boot ring will
no longer cover the hole.
4. Now you may paint the shift handles the desired color. Take care not to get paint onto the pivot bushings because
paint may cause a tight fit or binding.
5. Slide a shifter handle onto a pivot shaft with the handle offset pointing outward, followed by the included 1/4" flat
washer, 5/16" lock washer and then fasten with a 5/16"-18 nut. Repeat for the second shifter handle.
6. Fasten the female (shift rail) heim joint to the male (shifter handle) heim joint using the 3/8" shim washers, shoulder
bolts, heim joint, link plates, and 5/16"-18 nut. Repeat for the second shifter handle.
7. Now check to verify that the handles are vertical when the transfer case is in neutral and parallel to each other. If
the shift handles are not orientated properly, unbolt the heim joint link plates and adjust the position of the female heim
joint on the shift rail. Use the jam nut to secure it in the desired position. Reattach the heim joint link plates and check
your results.
8. Shift the transfer case through the following
configurations: 2wd High, 4wd High, 4wd
Low, 2wd Low, Rear Low, and Front Low.
The shifter handles should not be closer than
approximately 1" to the body in any of the
shifter positions. The frame and body will flex
while driving and can cause the transfer case to
pop out of gear or cause shifter binding if
sufficient clearance does not exist.
9. Once the transfer case shifts properly and has
sufficient body to handle clearance, it is now
time to fasten the shifter boot. Insert the
included boot ring into the shifter boot and slide
the boot down over both shifter handles.
Determine the proper location for the boot. Use
self taping screws to fasten the boot and ring
to the floor of the vehicle.
10. The last step is to thread the 1/2"-13 jam nuts
and shift knobs onto the shifter handles.
Notice parallel alignment of female heim joint and link plate.
