Sony Hi8 Camcorder Menu Wheel is

Question

Hi, I have a Sony camcorder Hi8 model CCD-TR748E. It has a menu wheel which is s rotating disk. You rotate the wheel to select menu options in the viewfinder. It is a bit loose and the menu items jump around. To select menu items you push the wheel in to select. I took the camera apart and it is soldered to the PCB and is replacable. I have surface mount re-work gear. I am looking for the part number from Sony for the small menu wheel assembly. Do you know the P/N for the wheel?
Thanks
