Does anybody have a diagram and an explanation of how the solid tub SQ motor transfers power to the fluid drive and in turn to the tranny and pump without any belts? When I look at that design, it’s a total mystery to me. | ||

There are 3 belts in a solid tub SQ washer...one that goes from the motor to the pump and one from the pump to the Transmission and one belt that goes from the Fluid Drive...that sit on top of the motor ...to the spin pulley. I have had both the reverse motor design sans solenoids and the first SQ washer my parents bought that did have solenoids. I am sure someone will dig up a pic of what I am taking about...
The fluid drive has an impeller inside the drive head. When the washer calls for spin, the impeller spins inside the head and there is a fluid that begins to spin and the upper part of the drive head has vanes inside that cause the liquid to "lock" and cause the drive to move, causing the head to spin and transferring that motion thru the belt to the spin pulley causing the tub to spin... | ||

The spin solenoid pulled the fluid drive bracket/fork down on the motor shaft to engage it and cause the tub to spin. If the spacing isn't right, the tub can turn constantly. A couple of adjustments were all that was usually necessary.
