Paul! The old bushings are easily slit with a graver and then pulled out; the new ones press in quite easily. The hardest part about re-fitting your new bushings is keeping the bores inline. This is easy with the proper Sunnen hone mandrel,or a very long reamer that cuts exactly to your shaft size plus clearance, but both are out of reach of the average enthusiast. What is even more important (and it tightens the sideslop at the points somewhat) is to shim the shaft endplay; The thrustwashers are available in various sizes.
