Working on this ‘69 750 S I’m wondering how the oil is drained on the central oil tank when it’s oil change time. There is no drain plug on the tank.
When I still had the central tank I would just detach the oil line from the junction block, then siphon out the remaining oil from the bottom of the tank
Ah remove the junction block. Risk though of wearing the threads in the alloy crankcase. Could just remove the strainer at the bottom of the crankcase and wait for all the oil to sump. Just kidding.I used to drain it out of that large screen 'bolt' with a 'sheet' of foil or similar. But then I got wise and disconnected the junction block as others have said. But the tank usually needs cleaning, so after that I also take out the screen and use mineral spirits (or gas) to clean out the tank with a shotgun mop. It's always a mess no matter how you do it. You just need to clean up afterwards. My zero turn and standby generator are the same way, always a mess, it's hard to believe where these guys put the oil drain. The easiest one is the wife's 3.6 Subie Outback, nice ground clearance, I don't even have to jack it up. It takes 7 quarts when drained properly.
Tried fastback body but don’t care for the look. I’ll suffer the messy oil change. Comfortable seat though. Came from Leighton.Yes draining a central oil tank is sh-t, one of the reasons I sold my '70 S, the oil tank on my '69 FB is a lot nicer.
