I have the cases split to replace second and third gears. Much to my surprise, the right side crank bearing fell out while I was scrapping off the old gaskets. With the exception of the left side balancer and right side main transmission shaft bearings, all of them were loose. I was able to remove the crankshaft from the left side with a little pulling. Are my cases screwed? For all these bearings, the manual has procedures to press them out and in. I can see how the bearings that are in the aluminum can get loose, but the crank bearings already are in steel sleeves. All of the bearings are in great shape. There is no evidence that the bearings were spinning in their holes. How did they end up loose? Overheating? My plan is to do some intentional damage to the holes and then press the bearings back in. Is this a bad plan? Any suggestions will be appreciated.
