Starting a new thread from my Engine Swap thread. Ended up tearing down the 150CC. Everything looked pretty good. Cylinder clean, no scratches. Piston good, rings intact. As soon as I took a hold of the rod (for the piston), I knew something was not right. Sloppy in/out movement, and a little rough. Definetely not the kind of fit to handle high rpm's. It is my first complete teardown, but I read a couple of threads about this failure. Can I take off the gears and bearings, then the rod and just replace (if shaft is not damaged)? Tooling alignment, tips, tricks? Thanks!!

Full circle rod so the crank needs to be pressed apart and pressed together again ,,,new cranks are very inexpensive ,,if it were my call ,,a new crank,,if the cylinder is ok,,hone ,,new rings and reassemble
