But while spotting the weeping, I noticed that there are three threads on the housing that don't have nuts on. Should they have? See the pic (a third one is round the back). There are no shoulders to take nuts, but what are the threads for, if they aren't supposed to have nuts on?
All are like that, if you look closely you will see that the bearing support housing doesn't have a flat area where the washer and nut seat flush against it. Don't know why it has those protruding bolts there but I can tell you that it has always been like that, my question is how many of us fly these machines for years and don't notice those missing nuts?
