On some very old instruments, the action is attached to the key board and everything has to be removed. If it will not come out do not force it - instead, push the action forward again and re secure the knobs. Remember this! Now carefully lift the action out of the piano. You will also see that the hole is bushed with a piece of leather or a little rubber grommet. If there is a pin on the rod protruding through a hole in the bracket, this must be put back in this position when the action is replaced. Important - look down behind the action on the left hand side and see how the sustain pedal rod coming up from the bottom of the piano fits into the metal damper lift rod bracket. Once the bolts are removed, pull the action back. Many very old "overdamper" pianos have a small knob in the middle and others have a small screw securing the centre of the action to the key bed. Some older pianos have a tab at each end that are turned.
Undo by hand the round knobs at the top of each action bracket. Remove this only if necessary - some are very difficult to put back in! See photoset "Removing the Action". The panels should be carefully put aside out of the way. The bottom panel is removed by swinging back the two top catches at each end or by pushing up a spring clip in the centre. Remove the lid that covers the keys by holding each end of the back piece and lifting it up evenly out of their respective piano slots. Carefully remove the top that is secured to the back of the bottom lid by two dowels. Open the top lid and reach in and undo the clips inside at each end.
All the repairs listed can be carried out by anyone who has a basic mechanical knowledge and apart from one or two exceptions, no tools are required. Printing off the action diagram will prove helpful.

The Guide should be used only in an emergency when a piano technician is not immediately available, rather than as a substitute for professional adjustment or repair. It should be used with reference to the five images at the bottom of this page. Grand owners are advised to leave their piano well alone. This section is provided so you may fix any small problem that may occur with your upright piano.
