Modifying 26 spline extension housing to 30 spline
I went ahead and cut my aluminum extension housing to the same dimensions as the iron 30 spline unit I had. It wasn’t that much, less than 0.25 on the diameters, so not much reduction in the wall thickness. I did have to cut the seal bore about 0.1 deeper, but it shouldn’t affect anything. The knee on the mill I have access to wouldn’t go far enough down to use a boring bar, so I had to circle interpolate the diameters. I will have to wait on the seal and bearing to make sure everything fits up ok, but if all works out I saved myself a couple hundred bucks.
