I have been working on the Griffon clutch on my Silverstone and have a question about the 6005 bearing that the clutch basket runs on. As removed from the bike this bearing was rough to turn and I figured the races must be pitted, especially as it was a very tight fit in the basket. Also there was little evidence of oil in the bearing. When removed and washed out, the bearing is fine and the roughness was caused by clutch crud that had accumulated in the open bearing.
My question is, do Griffon owners fit a sealed bearing in the basket and rely on the grease lubrication or use an open bearing and clean it out regularly? My local industrial bearing supplier has this bearing in stock with the double (rubber?) seals that I usually pick out if I need an open bearing, but should I? As the minimum amount of oil in the case is to lubricate the primary chain only and the bearing is pretty much out of any oil splash that might occur, would a sealed bearing be a better option?
Thank you,
Stan
