I am doing top end on my 1991 FLT. When inserting one piston pin in rod bushing, I got it cocked and ruined bushing. Have to replace bushing with rod in motor. My web reasearch shows I need Jims wrist pin bushing reamer and ball hone to use with electric drill. I have been told the Jims bushing reamer is not always needed, sometimes just hone. Is this true. If I heat rod end with heat gun, freeze bushing, and insert; it is possible I would not need to buy the Jims reamer. Rather spend the money on flathead parts. Also need to know good source to get hone, size hone, and grit. Any help appreciated.
