TOYOTA LOW GEAR 4.7:1 23 SPLINE
For Gear-Driven Transfer Cases ONLY
The installation of this gear set requires you to almost completely disassemble the transfer case. We have provided
illustrative assembly and disassembly instructions. If your transfer case is in need of a rebuild, now would be the time
to do it.
Here are a couple of points to keep in mind that will make the installation much easier if you've never disassembled a
Toyota transfer case:
1.)
Keep all bolts separated into groups as you remove them and label their container.
2.) Keep all small parts in separate containers and label as to location and origin.
3.) Make sure you have plenty of time and a clean, spacious area to perform the installation.
4.) You might want to have a qualified machine shop remove and install the bearings and seals on the new gears,
input shaft and in the case.
5.) The Trail Tamer instructions (in TT001) are to be used as a guide. The official Toyota shop manual is strongly
recommended for your particular application.
See Pages 3 & 4 on this instruction sheet to identify your
style transfer case & see what modifications are needed to your transfer case.
