I have a Corona with a few broken treble arm springs. What is the proper way of replacing the springs? Do I have to remove the whole treble machine assembly and remove each arm until I get to the broken springs? I have rigged up some springs temporarily to tension the arms for now but that resulted in air leaking through some of the pallets. Is it hard to get everything to line back up once I have replaced the springs? I’ll try to post some pics.

The dreaded spring replacement.
You have to unhook all the springs to relieve tension.
Then remove the whole assembly.
Find a wire or guitar string that is the same size as the original axle rod.
Start removing the original axle rod slowly and follow it with the wire (this is so all the key arms and springs don't fall all over the place).
Remove the axle only to where you need and replace spring.
It helps to screw down the assembly temporarily to so it doesn't move

that’s why it’s always good to ask. I didn’t even think about following it with something so they don’t all fall out. Thanks again for the many times you’ve helped me out.

I tackled this job last night and it went really well thanks to your advice. The hardest part was getting the rod to start coming out since it was pretty rusty. Replacing the springs did not quite fix my problem as I still have some air leaking from the valves. Is the a way to find out for sure if it is the valve pads or weak springs? I have air leaking both on the push and pull.

Could be the springs. You have to make sure you use the right gauge spring. Leaks can be from different places the bellows gasket, wood joints or the valve pads. What I do is go to a quiet area and listen for the leaks while closing the accordion.

I ordered the only springs Hohner had a available for Coronas. They are a bit thicker gauge than the others. I also suspect that the springs are the culprit since the action is really soft. However theese pads must be contributing to the leak too. I’m going to be replacing the felt pads first.
