I happen to own 4 Ariens S series and GT's. but have seen this on other shaft drive machines. They have a fiber disc that bolts separately to the hub on the flywheel then the driveshaft bolts, 90* to the same disc. They appear to be some kind of plastic, almost fiberglass-ish.
What would it hurt, to either; bolt the driveshaft direct to the hub on the flywheel, or make those discs from steel, more or less like a big washer? These aren't the rubber shaft couplers, as used on older Cub cadets.
I'm just completing an engine swap on the S-16H, and bolting the driveshaft to the engine is one of the few things left to do.
I don't see any kind of deterioration on these discs, but my tractors are all 40+ years old now. I do know of people who have had those discs come apart.
