A piano’s action assembly is integral to the instrument’s ability to deliver clear, harmonic tones. Poor voicing is a common piano problem — the notes play, but are muffled or weak. Repairing a piano’s action involves aligning or replacing the striking mechanism so the tones return to their original strength and clarity.

Whether you’re a novice or professional pianist, it’s important to align the action assembly with the help of an expert technician. Hiring a professional will ensure your action alignment or replacement is done right so you can return to playing harmonious music.

Why Repair or Replace a Piano Action?

In a piano’s action assembly, the hammers make contact with the strings to produce a tone. The action includes over 5,000 moving parts, including the hammer, hammer shank, flange and whippen. These parts can wear down with age and use, resulting in poor voicing.

Piano technicians repair and align the action by adjusting the hammers so they strike the strings properly. But sometimes very old or worn-down parts or the entire assembly need to be replaced. Here is a look into how a piano technician replaces a piano’s action assembly:

  1. Clean and buff original action cage.
  2. Install new felts and sandpaper.
  3. Rebush original keys.
  4. Replace leather back-checks.
  5. Hang and travel hammers.
  6. Prepare the entire assembly for regulation.

Hiring a Professional to Repair Your Piano’s Action Assembly

To avoid further damage, we recommend having a skilled technician examine, repair or replace your piano’s action assembly. A trained professional can offer expert-level advice and help keep your instrument performing at its best.

Many brands have changed the dimensions of their action parts over the years, so it’s essential to understand the new dimensions when rebuilding a piano. The wrong parts and dimensions could compromise the sound quality and limit the instrument’s vibrancy.

At Bradfield Piano, we use only genuine parts, like Renner action parts, to restore optimal voicing. Our factory-trained technicians bring decades of experience to the process of selecting the correct action parts for your instrument. Working with an expert technician will help preserve your family piano for many years and generations.
