Pathmaker Speed Shop Dana300 Teardown

After a few weeks of the Pathmaker sitting and me searching high and low for a local Dana 300, by local I mean, on Vancouver Island, because everything else has a ferry ticket attached and I’m a cheap cunt. I finally met up with my buddy Donny and grabbed an old case he had sitting out int he weeds for a few years in the back 40 behind his shop.

After shelling out “A Dollar per Dana” I headed home with my prize, to do a little filming as I tore down the case and reinstalled my outputs and figured out my new t-case mount that I picked up from my good buddy Dustin over at Back Door Fab, a local fab shop with a plasma table and a brazillion different files and designs of almost anything offroad you can imagine.

The fluid surprisngly clean when I drained it out, considering it had been laying in the weeds for a few years, so I tossed it up on the bench and started to tear into it. Thankfully a Dana 300 is a super easy to tear down case, with not much more than a socket set and a 3 jaw puller needed to tear it all down and strip the outputs off so you can remove all the gears.

Once I pulled the cover off the case I saw some metal filings on the magnetic drain plug. Not a massive amount for a 30+yr old t-case with an unknown life. Of course I had to run to Princess Auto for a new 3-Jaw puller, and a new Torx bit after breaking two of mine trying to take the input plate off. After breaking two bits I just pulled out the ole drill and drilled it out, as soon as the bit cut into the bolt it spun right out thankfully.

After tearing everything apart fully and tossing my new truss mount onto the case I only at that minute realized that I had unknowlingly ended up with another “Short Tail Shaft or Texas Bolt Pattern” dana 300 which came in a limited number of International Scouts. While everything else on the case is the same, unfortuantely I have an upgraded JB conversions rear 32 Spline output, which is designed for the long tail shaft Dana 300 found in the Jeep CJ, which I thought was what I was buying.

So after all of that, this case is not the one I need and I’m back on the hunt for another Dana 300, long tailshaft version so I can get the Pathmaker back on the trail. On that note, know of anyone that needs a short tail shaft d300? This one will be going up for sale as soon as I can find another case!
