Heat the bare case havles to 350° the bearings will fall out ..install them the same way. Pressing the bearings in or out of the case will cause a loose fit and the bearings wil have a tendency to spin in the case and ruin the case.

You can put them in the oven at 300°-350° and they will fall out...might have to give a little tapping and the new bearings are installed the same way by heating the cases and set the bearing in place with a needle nose pliers and a light tap to seat them in.
You can also use a heat gun or a torch if you can keep the temp uniform and not over heat the case..too hot the seals will be no good....best to remove the seals and replace them as well after replacing the bearings.

Thanks Les. I will follow your advice. I'm also excited to try out the 26cc top mod kit i bought from you. Looking forward to better weather and longer days here at the west coast of Norway.
