My brother works at classic motorcycles and had an adjustable “C” spanner, but unfortunately it did not work as the body is to thick and not allowing the spanner to close before it touches the opposite side of the main body of the water pump. The nut is so loose that it can be turned back and forth with two fingers, but it obviously requires the proper spanner to compress the seal.
Does anyone know where I could purchase this tool
