Thanks kindly for helpful information. Senility and ending up being mostly a tuner leave me very skittish about doing things which seldom come to me. No shop- I do all work in homes. I've been very glad I did it that way. Customers have been amazed at the involvement in something so "simple" as a regulation, and they have been universally incredibly glad to pay me.. But I do get a bit worried- no more than that. I got into the business too late....

The outside brackets are all the same. So measure your middle brackets and count how many you need (some are 2, some are 3). End bracket: a little over 8 inches (205 mm) Long middle bracket: 6 5/8 inches (170 mm) Short middle bracket: 5 3/4 inches (140 mm) Count on doing a completely complete regulation.

Be careful getting the action out, since the hammers may be up too high to clear the pinblock. If the drop screws bury into the pinblock, you may have to break/cut the brackets. Usually the glide bolts are set to raise the frame quite a bit, so you may be able to raise the bolts if necessary to release the action. The replacement procedure is pretty easy, but you'll have to set the spread using calipers or whatever. The newer model YC's spread is 113.5mm, but I can't recall which serial #'s those are. You can call the service dept. and ask for their advice. Check your resource guide for their number, as I don't have it handy. You should be able to get the brackets for free, and they will offer some compensation, but it's not much. You'll have to charge the customer for re-regulating the piano, especially if you had to move the glide bolts to get the action out. You'll need some longer screws to mount the stack, since the new bracket feet will be taller than the old ones. Just plug and redrill. Often, a previous technician has adjusted the letoff buttons to compensate for blocking hammers. Most likely you'll be screwing all the letoff dowels back up quite a ways to get the action to work again. It's not hard. If you can regulate an action, it's a piece of cake. Good luck and have fun.

I did ONE several years ago, with only modest success. Its been a very long time since I have seen this piano, and am not even sure the action will come out. Im in need of sage advice.
