I believe I have a VN Recon in my shop right now. I just torn the front end down, it was leaking. When I first opened it up I noticed the seal area had been built up with brass and sanded back down, really not a bad job. BUT inside I found where alot of the shafts were galled and the inner edges were pretty mangled from someone "muscling" out a bearing race. The seals that needed replaced had been installed wrong. The spring that keeps the inner lip tight had been smashed by the bearing. Why didn't it leak when new? Or should I say "new".....because the gear cases were filled with some unknown oil...VERY thick. Smelled more like licorice than anything else and was a dark brown, it was clean, all but the large amount of shavings in the bottom from the bearings riding on the galled shafts. The thickness of the oil was more like cake batter than anything else it would not even level out when it dropped on the floor. I could put it in a pan and hold it upside down it would take approx 10 secs for it to start to form a drop...
Oh and this unit ONLY has 56hrs on it.....Nice paint job though.
