Removing a Key Weight
1. The main components of the weighted-key action consist of the following: the 88 keys,
two rods, 88 key weights, and support brackets for the key weights and rods. There are
seven 12-position brackets and one 4-position bracket.
Note: Key weights are attached to one of the two rods that span the length of the
keyboard. The fi rst rod is referred to as the bass rod and the second rod is referred to as
the treble rod. The fi rst rod (the bass rod) begins at low A and extends to G# above Middle
C. The second rod (the treble rod) begins at A above Middle C and extends to High C.
2. To replace a key weight, identify the section with the broken key weight and remove all
the keys from that section. The key weights, rods, and support brackets are now visible.
3. There is a locking clip at each end of the keyboard. To remove the locking clips, use a
standard screwdriver to pry the locking clips off.
4. Pry the rod up from the support bracket. The key weights remain attached to the rod.
5. To remove the key weights from the rod, move the key weight side to side and pull it
away from the rod. The key weight should easily pop off the rod.
Note: The natural and sharp key weights are physically different. The sharp key weights
are smaller. When you remove multiple key weights, do so in a way that you will be able
to place the new natural and sharp key weights in their correct positions.

6. Remove the broken key weight(s) and inspect the other key weights for reliability.
Replacing a Key Weight
1. Each key weight has a strip of red felt attached with pliable adhesive. Be sure the red felt
extends onto the upper surface of the top of the key weight.
2. Place the key weight in position against the rod and snap it onto the rod with slight
pressure.
Note: Be sure to place the sharp key weights in the correct positions.
