Clockwise turns the agitator relatively easy; counterclockwise more difficult tuns the tub. Tub turn making a semi grinding noise.
It is hard for me to discribe how the pulley should turn. It will have a spring feel to start and they it should be heavy but not difficult as long as there is pressure keeped on the pulley. There may be something stuck between the tubs if it is very hard to turn. If you remove the two screws from the lower part of the front paenl and then the two 3/8" that secure the top. Lift the top and remove the spash ring and inspect it. Use a coat hanger to fish out blockage. If all checks out it will be the motor or the timer. Also when the front is off check the area where the transmission goes into the tub for leakage.
