spin cycle did not engage

researched potential causes, found cluch dust under the washer and determined that it wouldn't engage because clutch was too worn. ordered the assembly, removed agitator from inside the tub as it is connected to the gear shaft, turned washer on it's back for access to motor, unattached the direct drive water pump from the motor drive, unbolted the 3 gearcase mounting bolts and took the entire gearcase, shaft, motor, etc... together, out from under the washtub. the clutch slides off the gearshaft with a little fidgeting and the new assembly is easily installed where the previous was. put everything back together... then... spin spin! worked perfectly
