G. Remove the hammer stack.
The hammers are mounted on a small metal
frame attached by four brackets to the wooden keyframe. Remove the
screws – 2 per bracket, for a total of 8 or 10. The screws may vary in size;
consequently, mark each one in such a manner as to insure its return to the
original position in the keyframe. Lift the action “stack” from the keyframe
and place it some where safe.
Pianos with leg bolts sometimes present a problem when attempting access to
all 88 keys. It may be necessary to omit some key solenoids on both ends of
the keyboard due to the interference of the leg bolt plate in the keybed.
To determine this key access –
A.
Remove the action from the piano
B.
Measure from the keyframe rest block (on the bass side) to the first leg bolt
plate. Transfer the measurement to the keyframe. (see figure 1A and 1B -
Measurement X)
C.
Now measure from the keyframe rest block to the leg bolt plate in high
treble. Transfer this measurement to the keyframe. See figure 1A and 1B –
Measurement Y.
