SPECIAL INSTRUCTIONS:
When assembling the transmission to the transfer case, DO NOT FORCE the two gear boxes together. If the shaft is
too long, there is the possibility of pre-loading the transmission bearings for premature failure. Take the extra time to
make sure that the shafts do not bottom out internally. If there is an interference problem, it may be necessary to grind
the end of the new output shaft to obtain the proper length.
All Ford transfer cases, whether NP205 or NP208, always require a 31 spline male input shaft. We have seen some
variations as to the stickout length of this 31 spline output shaft. Before assembling the new transmission to your transfer
case, you should compare the stickout length to the original transmission and make the necessary adjustments.
Before assembly of transfer case to transmission, the transmission tailhousing will have to be pocketed for clearance of
the transfer case shift rails and cross link.
1. Align U-shaped notch of adapter with rearmost cylindrical boss of tailhousing, keeping in mind that the tailhousing's
bolt pattern aligns with the adapter's tapped hole bolt pattern. Once aligned, transfer outline of notch to tailhousing
with felt tip marker.
Optional Item
715528 NP205 Transfer case
shifter brkt.
2. Take a 1/4" drill bit and wrap a piece of tape around bit 7/16" from the tip. This serves as a depth gauge. With a hand
drill or drill press, drill as many holes in the outlined area as possible.
3. With a cold chisel, knock out the remaining material. With the shift rods in the fully extended position, make a trial
fit of components to ensure that the pocket depth is enough to clear shift rods and cross link.
