Stiff Damper Rail

[Jim Keaney]

I was tuning a small no-name console piano, and noticed that the  
sustain pedal was not working properly. Well, the problem is a very  
stiff damper lift rod. I was unable to lubricate it using some liquid  
graphite, and I'm wondering if I need to remove all the dampers just  
to lube to the rod. Does anyone hopefully have a much simpler solution?

Thanks!
