SPECS ON PILOT BUSHING, CRANK PILOT HOLE ID AND INPUT SHAFT

I'm sorry, I didn't make something clear. Rebushed was the term used by a crank regrinder that didn't know the specs. It doesn't mean the pilot bushing. This crank may have been an automatic crank that was drilled larger improperly. It is slightly large and out of round. So a machinist told me he could drill the hole larger and rebush it. I wanted to know the specs to do this and to know how much crush a new bushing (metal, I assume) to make it to stay put and then what to drill that out to, so the pilot bushing has the proper crush. Also I have another 340 crank that I installed a pilot bushing in, but the input shaft is very tight. There seems to be only .001" clearance.

I found a bushing shrink calculator at oilite.com that will tell you what od you need to make sure that your id falls in the range you need after it crushes on install. You can't reliably machine oilite, it tends to close up the pores, so it's better to avoid shrinking it too much and reaming to size.

That said, are you SURE you don't want the bearing?
Any particular reason?
