My next project uses Toyota t-cases and Rockwells. The Rockwell flanges are 1410. I could adapt them to use Toyota joints but I would have to get fancy about it, and I would rather keep it simple. I also only want one size of u-joint in my driveshafts so that I only have to carry one spare, so a bastard driveshaft is out.
Sooo...I chose to rework the Toyota flanges to accept a 1410 flange. I went down to the local CatCo and ordered Neapco p/n N3-2-159. This is what I got, beer can for scale:
It's a 1410 flange, 3.75" bolt circle with 7/16" hardware. Neapco specs say that the max. diameter of the flange is 4.625", but in reality it's just shy of 5". The flange has a male pilot that is 2.75" in diameter.
Anyways, I took a factory Toyota t-case flange and pounded the dust shield off:
Then I stuck it in a lathe, cut off the flat portion of the flange, and turned it down so that the OD was just slightly larger than the transition between the cone and the flat surface on the back side.
I finished the flange before I took any more, but you should get the idea.
Kert cut a donut out of a piece of 3/8" plate. It was ~5.15" OD and ~2.4" ID. It then got eyeball centered onto the existing Toyota flange and Kert welded the two together.
After it cooled for a while, I stuck it back on the lathe, turned the OD down just enough so that it was round. Then I faced it to make it flat. Then, I bored out the recess for the pilot on the 1410 flange. I overshot the pilot by ~.010" but I think it should still be ok. I don't do any high speed running and if it's an issue, I'll just lay a weld down to fill it and put it back on the lathe.
Then, I set it across the jaws of a vice on the mill and used the 1410 flange as a guide when drilling. Bolted it together with the 7/16" hardware, and I now have a 1410 flange for a Toyota case.
