Took the lever mechanisms apart today...
bad news one of the articulations was really worn. As were two of the 4 pins... so another $165 worth of parts.
1 new articulation
2 more bearings (decided to replace all of them)
4 pins
new knobs for the steam and hot water valves
various washers, o-rings and rubber bumpers
Good news this will be like a new machine... not many parts will not be replaced....
