Hello all, I don't know whom to tell this to because there was no name signed to the posting. Kimball put out what they called a grand and vertical troubleshooting manual probably 1 to 2 years ago. It has a very good description for repairing pulley keys, providing the keys are not to far gone. If that is the case than you might have to use some kind of added insert. I'm sure Kimball has these manuals left over even if they are getting out of the piano business. The manual I speak of is very well done and I would recommend it, especially for newer technicians to the trade. Doug Hershberger, RPT
