Just because the primary valve chest is smaller does not mean it is any easier. The first step is to remove the screws holding the "L" channel board in place.

Next the junction board where the lead tubing was connected is removed from the chest. Notice the lead stubs are still in the junction board.

Remember the junction board with all the lead tubing stubs. Now it is time to remove the stubs. Trying to pull the stubs out resulted in breaking at the wood line. Another method would be needed to remove the stubs.

After the sealant (burnt shellac) was removed I used a screw that was just a size larger than the tubing to screw into the lead and then pull out. Be careful not to use to large a size screw or the lead will be imbedded into the wood. I used a small box end wrench to assist in pulling out the lead.
