The spring is much heavier than on the other damper levers and is often the first source of noise as it will wear through the spring punching. Replace the punching (if its there )or lube W/ V.J. Tom Driscoll Tom, I don't know if you have read the other responses, but that's what I initially said it's purpose was as well. However, I don't recall finding auxiliary dampers generally installed on vertical pianos with only one damper lever lift rod. However, I do find the dummy levers installed on vertical pianos with the bass damper lifting feature (middle pedal) that requires two damper lever lift rods. If these findings are correct, that would negate keeping the rod away from the dampers as the primary reason/purpose for the auxiliary damper lever. Regards, Keith McGavern Registered Piano Technician Oklahoma Chapter 731 Piano Technicians Guild USA Keith, I had not read the other responses, but as I see it, the function of the auxiliary damper is to keep the rod up against the action rail and away from the levers---split damper rod or not . Indeed most compact actions have the split rail for the middle pedal-bass sustain feature, but a one piece rod can also interfere with the damper levers if allowed to swing away from the rail and touch the levers with the pedal at rest.
