So, you replaced #515, #508, #543, and #308 had nothing between the drum and the front surface of the felt. From the diagram #454 glides would have been replaced as well.What's puzzling is, all of that was disassembled. All suspect parts replaced.
Noise persisted after.![]()
If all of that was replaced; the only thing I can suspect is the ruff handling and banging re-alighned surface area's; within the cabinet.
When the square is out; can cause some tweaking of the cabinet; which might place some stresses that would result in parts rubbing against one another?
That may or may not be the case, I would think ruff handling may likely to have knocked something loose that was impinged somewhere, and was small and undetectable; ear ring or other?
