Washer Operation (Slipping Belt Clutch Mechanism).

Spin and agitation are accomplished by reversing motor operation.
Proper operation of the drive
mechanism is dependent on correct calibration of the idler arm tension spring.

The speed (rpm) is reduced through the idler gear to the crank gear. The connecting rod moves the sector gear
back and forth for agitation stroke. The brake * LGS spring grips the transmission to prevent gear case and
spin tub from moving with agitator.
