I replaced tub seal kit, new lower bearing in milk stool, transmission and a new belt. After installing all the above the pulley does not release the brake to spin nor does the pulley go down to engage the Helix. I removed the motor and checked the motor rpm with a digital tach for rpm and also for the correct direction depending. I thought maybe the brake was too tight to see if would at least spin so I sprayed the brake rotoe with spray silicone but that did not nelp. I also removed the pulley and helix to inspect and they are fine. Any suggestions would be appreciated. Phil

ANSWER Hi Mr. J. Use a little of grease on the lower helix -to trans.-spline dogs so the helix will easily slide up and down on the shaft splines. Anywhere 2 pieces of metal contacts one another then it needs grease in between the 2 sparingly so they work together(if not already in a lubricated area). As you rotate the main pulley one way the agitator will operate and you will hear a click,click,click. In the opposite direction the pulley upper washers will engage the brake rotor and release the clutch plate (similar to a car manual clutch) which spreads open and releases the brake pads. If the steel washer part # 40063201 is not placed above the pulley first as the plastic fiber washer above it part # 40065701 they will not work correctly and engage the brake rotor properly. If the bottom trans. shaft pulley bolt is not lok-tited on it will work loose and not allow the system to work. You then will hear a clunk,clunk,clunk and see the bottom bolt loose. Thank You.
