    Replace broken gear on Riso rz390

    The lower gear in the thermal area broke on this riso and I just got the parts in for it. I read on here that this was a common gear that breaks. What is the easiest way to go about changing out this gear?



    Parts number is 612-10010-008
    Description is GEAR; M1x20x6

    UPDATE : Managed to find the service manual for it. Gear replaced.
