Went to You Tube and watched a video and it made it simple because no directions came with parts. Video told how to take apart and exactly how to put it together with new part. Very easy with knowledge before starting. We didn’t even know the secret to getting top off or how the old and new parts were marked exactly the same just in different places. Watch this and you will see how simple. https://youtu.be/vm3L95t2ejo
On replacing the terminal block....The new screws had to be rethreaded into stainsteel, it was a self tapping screw but this was the hardest part on replacing them.
