Hi,

Honestly I wouldn't bother oiling those old bearing, just remove and replace with the newer sealed type unit. I'm pretty sure that they would be RLS5 bearings which if you go direct to a bearing shop you'll get them far cheaper than from any eBay seller that's for sure.

When you say about turning the blades are you saying that they are stuck rock solid, because if they are you will have to throw those bearings out as they are the old open type that let every bit of muck and moisture in, thus they cease up quite easily.
Let me know before we go any further.

Cheers,
BB
