Pilot bushing direction

You will have to verify the bore ID. If you broke one already, there's a good chance your crank is drilled, but not honed to the correct diameter to accept a Bronze bushing. The chamfer is a lead-in for the "press" operation. Standard engineering practice.

Go to the manual transmission section and look at the Sticky about 273 pilot bushings.
The roller bearing does NOT fit without mods.

I did this over the summer for my /6.
