400/450 stroker....Cheap parts, lotta work.
Here is the tool to remove the intermediate shaft bushing.
Bushing removed and still attached to the tool.
Bushing installation tool............
Tool is position to install bushing. Lightly tap the top of the tool with a hammer until you feel the bushing seat against the block. Don't hammer too hard after the bushing seats against the block or you will mushroom the bushing. As you drive the bushing in, there always seems to be some brass scrape off under the bushing flange. I stop about 1/16" before the bushing seats and use some air to blow away the loose brass before finishing seating the bushing. After seating, tightening the large nut on the tool draws the tool out of the bushing and burnishes the bushing to size. Then briefly I install a pump and drop the intermediate shaft into the block and make sure intermediate shaft turns freely.
