:O that's a huge project. I'm afraid if I attempted such a thing I would be left with a bag of spare parts.
Thank you for the tip, it's a really good idea.
I was planning on using WD-40, toothbrush and rags to remove the old oil and then removing and cleaning out the Wd-40 to finally oil it up properly with the appropriate oil.
Weirdly enough I was expecting to see gummed up oil on every part and it doesn't seem that bad..
