Well we will see just how good you guys are. I've got a 20 ton Carrier chiller that needs TXV changed out. I can either solder in the new one or change out the " guts " of the old one. This is what Carrier is calling a cage replacement. But in order to do this I need to use the "provided" X-29151 tool. Of course the tool isn't there and none of my Carrier dealers tech support know what it is. Anybody?
