: dear Mr. love:
: you show the layout and part numbers for this system.
: Can you please supply item names to match the part numbers? I have this system but removal of 930-030
: requires special wrench. What is name of this wrench?

It would be the "socket set" shown on the picture on the lower part. Hardware stores carry these for little money. Sometimes, an adjustable wrench will do. Terry
