Input shafts and Crank flanges are different with each manufacture...
The polished end of the input shaft is approximately 1.00" long..... and on a FE it goes into the crank about .375"inch .....so we made the bronze oilite bushing to fit into the crank and have a outside flange to give more support to the input shaft to run on.....
The flange on the pilot bushing is about .400"inch so we are working with only .775"inch on the polished input shaft.....
Here's some photo's to show....
Bushings are much better then roller bearings.....because they can handle slight variations between the crank and input shaft.....
And if you are only going to be inside the roller bearing .375"inch.... just not enough for us...
