I'm finally ready to put my 1963 75hp Starflite back together. I started the rebuild almost 2 years ago, but a busy schedule kept me from finishing. I just got the block back from the shop and I have most parts needed for the powerhead rebuild.
I have found most parts that I need NIB. However, some of the parts have a slight rust on them. I suppose that the protective oil rubbed off onto the packaging that they were in over the years, exposing the metal to air. So even though the parts are new and never used, I need to figure out if I need to clean them. Obviously, I won't use a part that is heavily rusted; I'm talking about a very light rust coating. Since some of these parts are crank seals and bearings, tolerance is a huge issue. I don't want to remove material to the point where the tolerance is out of whack and won't work.
I'm sure that I'm not the only person to rebuild an old motor like this and found some slight rusting on the decades-old replacement parts. What do you suggest? Hit the rust with emory cloth? Leave it alone since a very small amount of rust won't hurt?
I've included some pics, though it's hard to see the rust. The crank seal has rust on the outer face that mates with the crankcase and a few small rust spots on the side. The upper crank bearing has a bit of rust on the outer face as well. I also have some connecting rod needle retainers that have some sort of patina on them. Should they be cleaned or left alone? Thanks.
