P/N 82300234.
INSTRUCTIONS:
This new input gear will only fit the NP231 transfer cases. The installation of the gear will require the complete
disassembly of your NP231 transfer case. Since the transfer case has to be completely disassembled, this is also a
good time to install a short output shaft kit (fixed yoke kit) if you already have not done so.
If you've never disassembled a New Process transfer case, here are a couple of points to keep in mind that will make
the installation much easier:
1. Keep all bolts, nuts, washers, etc. separated into groups as you remove them. Make sure you keep them in a labeled
container that indicates what part of the transfer case they came from.
2. Keep all small parts in separate containers and label as to location and origin.
3. Make sure you have plenty of time and have a clean, spacious area to perform the installation.
Remove the front yoke nut with a 1-1/8" socket using an impact wrench. Remove the rear case bolts.
A 10mm 12 pt. socket is needed for the spline head bolt and a 15mm socket for the remaining bolts.
NOTE: The two black oxide finished bolts are located at the case dowel positions and require a
washer under them. Start to remove the rear case from the front case by inserting pry bars at the
cast-in locations
ONLY! Pry apart evenly to break the sealer bead along the case mating surfaces.
The front output shaft and chain should be retained with the rear portion of the case.
