The Crank Position Sensor (CPS) reads off the side of the flywheel. Removing the case gives you a good look at the massive crank assembly…
This flywheel scraper oil return looks a very much like the design used in my ‘46 Knuckle to evacuate crankcase oil. Big Twin’s, K’s and XL models used this method for decades to transfer crankcase oil over to the gearcase for pickup and return to the oil reservoir. This method was dropped in 1977 on XL’s and with the advent of the Twin Cam Big Twin’s.
I am somewhat surprised to see S&S choose to stay with this dated, “old school” design. IMHO, the mini sump with direct oil pickup is a far superior method of handling returning engine oil. For what it’s worth, I see that Indian’s proprietary V-Twin engine uses the same early H-D design as well.
I can’t help but wonder if this old method continues to be used simply because it is available.
Thanks for the great presentation, Hoist; good stuff!
