    ATC 70 Oil Pump Drive Sprocket removal?

    I need to replace my 70's oil pump drive sprocket.
    Can I remove it without splitting the crankcase?
    I presume the oil pump drive shaft end is threaded where the sprocket goes on?

    Do I need to hold the sprocket some how and try and unscrew the shaft from the oil pump side?
