My 4701 does this also, ticking kind of sound. Figured it has something to do with the fuel or hydraulic pump.? Really don't pay attention to it anymore.
It is the electric fuel feed pump. It continues to pump fuel through most of the system, which acts as a coolant & carries heat away from certain components, after the engine is shut off. Nothing to worry about.
