When I lubed my 4600 for the first time they were really rough. I used my 1/2 inch drill attached to the end of the screw and ran it back and forth the whole length about 20 times adding grease and wiping off the excess at the end of the full in and full out runs. They freed up and were slick as could be.
When I found a rough spot I would run it back and forth right there, adding wd40 and then grease. I inspected the area of the screw but found no damage. I think old dry grease/ shavings/rust was caked in the screw threads. Jim
IMHO, I am not a fan of WD40 for other than applying to unimportant places, i.e. lawn mower wheel axles... or, better yet, for coating bass lures (great for catching fish!). I carry a couple cans in the boat all the time. I wouldn't use it on a HJ, the stuff has a tendency to gum up after a while and, frankly, I don't think it has all that good lubrication properties. If you want to use a light weight oil, I'd recommend something like TriFlow or Lubriplate spray oils. WD40 does work great as a lubricant when machining aluminum.
