DODGE 4WD TRANS-23T NV4500 5 SPEED
TO FORD NP205/208 & B/W T/C's
NOTES:
The cutoff length of the original Dodge NV4500 output shaft can be determined by the amount of the desired stickout
length of your new 31 spline spud shaft. Over the years, we have seen some variation as to the required stickout length
for Ford 4WD transfer case input splines. This length will vary between .750" to 1.50". The best way to determine your
requirements is to measure your existing 4 speed transmission that is being replaced. Determine the exact protrusion from
the face of the rear adapter housing on your original installation.
Use the following procedures to determine the cutoff location.
1. Test assemble the new adapter housing onto the back of your NV4500 transmission.
2. Slip the new coupler onto the output shaft and push it all the way forward until it bottoms out on the inside splines.
3. Measure the stickout length of the 31 spline spud shaft from the back of the new adapter housing.
4. Compare this stickout length to the original 4 speed stickout length.
5. The difference between these two measurements will be the amount that you will need to shorten the Dodge
transmission main shaft. In some cases, the 31 spline spud shaft could be shortened as an alternative.
6. Remove the tailhousing for transmission main shaft modifications.
7. Using the necessary safety protection equipment, shorten the output shaft to the desired length using an abrasive cutoff
saw. Debur any sharp edges.
8. Reassemble the adapter housing and double check the spud shaft stickout length.
CAUTION:
DO NOT FORCE the transmission-to-transfer case adapter assembly together. Interference with the spud shaft spline
area can cause pre-loading, which will lead to transmission and transfer case failure.
We offer P/N 715528 transfer case shifter bracket for use with the NP205 transfer cases
