Young Chang Action Brackets

Aftermarket replacements for 1990s era Young Chang, Weber, Wurlitzer pianos with expanding or cracking brackets.

These grand action brackets are made of polyethylene glycol. This polymer is extremely strong, heat-resistant, dimensionally stable, and has a very long lifespan, making it ideal for this application.

Frequently Asked Questions:
Q: How can I determine if the piano I'm servicing is affected by this problem?
A: If it's a 1990s era piano made by YC with grey (not gold) brackets, and the hammers are blocking, or the brackets have cracks, this is likely the case. If you are not certain if the piano was made by Young Chang, measure the foot of the brackets where they attach to the keyframe. The end brackets should have 205mm feet, and the inner brackets either 145mm or 170mm. For further confirmation, the total height of the bracket should be about 105mm. The measured numbers may be a bit larger as a result of the pot metal expansion.

Q: Will Supply88 make brackets for other piano makes/models?
A: No. The demand would need to be much larger to justify the development effort.

Q: Will replacing the brackets correct the regulation problems caused by expansion?
A: No. Expect to perform a complete regulation as part of the job. No replacement bracket (ours or those made by anyone else) can be expected to be an exact match for the factory brackets, which were never produced to exacting tolerances. The factory regulation worked only for the factory brackets. The slightest variations in the position of the hammer and whippen rails will greatly impact the regulation. In addition to regulation, you may need to make dag and cheek block adjustments to restore a proper strike line (especially in the treble). The product pages below contain more info and instructions.

Q: The expansion is so bad that I can't remove the action. What should I do?
A: It will likely be necessary to destroy the brackets in order to get the action out of the piano. The brackets might crumble if you provide them with enough impact or stress. We've heard of situations where the technician had to saw through the brackets.
