I am helping a friend rebuild the headstock on his older PM932. The manual is calling for shielded bearing's. Some of the bearings in the headstock are opened and some are sealed. I can see using open bearings in the bottom where they are sitting in oil but what about the upper bearings. Should sealed bearings be used or would there be enough splash lubrication to use open bearings.
