Dana 300 TeraLow Page 2

projects

 

**NOTE** I was using both a digital camera and a regular camera during this install, some pictures are not back from being developed.  You will see more soon.

We started out by disassembling the second Dana 300.  The fact that neither of us ever did this slowed us down a little.  We found that following the manual was useful.  A press would have been helpful and so would a good gear puller set but we managed.  It is almost impossible to remove the bearings without damaging them, so it is advisable to invest in a transfer case rebuild kit (a) this kit includes all the bearings, seals, and gaskets you will need.

I got to work with the grinder, a notch needs to be formed in the corner of the bottom of the transfer case. (b)   The only purpose for this is for clearance when installing the intermediate gear.  You should not need to grind into the area where the gasket sits.  The grinding took about 15 minutes and after a good washing to remove all the metal dust we were ready to start reassembly.

Stage 3 - Reassembly

I followed the manual for the steps to reassemble the case.  It is evident that it is important to read carefully because the case fits together sequentially.  The front output shaft assembly is installed first (e & f), then the rear, finally the intermediate gear (g).  With all the gears reinstalled a gasket was added then the bottom cover was reinstalled.  The case was now ready for installation.  (h) is a shot of the old gears.
