I don't mean to contradict Bob as-if to to diss or dis-miss him or any way be mean, I'm just realying my experience with the many Sachs Aris FW's I have as an example of experiences can vary so much !

I've always flushed them, the ones with the port holes, then blow come light compressed air in the hole, and relubed them. When I use oil I let the excess drip put face down or up on a paper towel overnight at the least. I've used motor oil of various weights, plus some Lucas White Lithium grease mixed with a little oil of late. Standard motor oil is a bit too thin on it's own for my liking. Most of my Sachs are the ones with the red "seals". Funny thing though, I've never had any sort issue with them regardless of what I've done. The factory grease as Bob mentioned, is so thick it's freewheeling in both directions in waiting, if not broken down and in some way. Even the relatively new ones I used back in the 90's. I think I've used both auto degreaser and WD-40, but as I found, WD-40 is a poor degreaser. I likely used diesel at some point also. I've used FW's my entire life and the only one I remember siezing is the original SunTour from my '83 Stumpy. I never oiled it at all and it sat out in the rain at times during a brief stint of college. I didn't know any better at the time. They were easy to get though, plus cogs and spacers. So to me at the end of the day, there's a zillion ways to do things, despite what I or anyone says is their way. The worst thing of all is any self-imposed guilt for believing something was done wrong and punishment is to be served, that things shoulda woulda coulda been different,as if it woulda coulda shoulda made or makes a difference. It's like a backset driver ! Easy to give commands and question everything when you're not there ! So smile Regardless.
