My old G-E had that kind of coupling and a goofy clutch. I had nursed that machine for some 30 years, motors, relays, timers, gear boxes and the goofy floating tub gasket.... Finally gave up when the porcelain tub rusted out. Now have a Maytag Perfoma. It to has had its share of clutches, timers, motor and pump. But it still works but the pump is now getting louder and louder, I think the non-servicable bearing is giving out. I expect that it will spring a leak when it does. The last time the pump failed with that rumble noise chunks came away from the cheeks of the drive pulley, strange, it made continuous thump-like rattles when the chip out in the pulley engaged the belt every 1/2 turn...
I hate to buy a new washer with electronics, the rule with those is when they fail the brain is big bux if not obsolete...
I have been lucky finding dishwashers with mechanical timers, so far...
