All of the trim can be replaced without removing the tank, with the exceptions of the Flush Valve Assembly

gasket or water divider must be replaced, then the following procedure should be used for disassembly of
the tank. NOTE: When disassembly of the tank from the bowl is required, all three expansion plugs (#IFO8)
must be replaced.
1. Shut off the water and read the assembly instructions.
