fluid drive
Yep,the fluid drive is basicly a slip clutch-active in spin mode,it lets the tub
get up to speed without bogging down the motor,Ones for reversing motor SQs-
Ca.1973(?)-1980 mount to the shaft with a roll pin and have a one-way clutch built
in.Earlier solenoid shift clutches have a bronze bushing center and slip over the
motor shaft,a cone clutch section on the bottom of the fluid drive engages a mating
section on the motor pulley when the spin solenoid pulls the fluid drive down to
begin spin.Internally,the SQ fluid drive is similar to an automotive torque
converter except no "stator" section-just a dome-shaped driving member with fins
underneath to drive the internally finned outer housing via the light oil inside.
