@batman,
there may possibly be a very slight amount of play, generally all the edges do appear to be sharp and in good condition but I guess it can't hurt to pack it with something but what exactly is the 'bearing mount' of which you speak. I can't find it here, is it some sort of heavy grease? What about the orange RTV I've seen on the Old Feller thread, is that good to do if there is a very tiny amount of play?
Regarding the oil seals is it simply a matter of pulling out the seal and o ring with a pick and putting the new ones in?
When you say the washer looks a bit rounded do you mean where the flat part is meant to be bent up against the nut? The washer on my bike is pretty thick, looks a lot thicker than the ones I've seen on other threads, appears to be hard to bend.
Also in the shot below, I have a blue dot painted on the oil seal and engine, why is this? is it simply to tell if the original seal has been replaced?
Does the collar [36] press against the bearing [31]
thx.
