Machining flywheel hub to remove oil seal groove
Anyone ever done this? The groove in mine is about .005" (.0025 would clean it up) on a crankshaft grinder. Looked to see if there was a "Micro Sleeve" like engine builders use on the front and rear of crankshafts, but nothing for 68mm. I think it would be a better fix overall than just spacing the new seal. Thoughts?

Not entirely sure what you're asking here. Pics might be a help.
I'll put it this way, on all the engines I've built I've yet to have any appreciable leak from a rear main seal, and some of the engines were high mileage FC engines with high mileage flywheels.

New rear main seal should not have a problem conforming to an existing groove that shallow. I'm not sure about the rear main seal on the rotary, but I have been taught in the past to seat the new seal a tiny bit deeper than the old one so that the lip does not ride on the exact same spot. Again, I'm not sure if the rotary has the space to be able to do this.
