have you got a bosch motor? assuming its a gen2 from the size -
if so buy sprocket by KMC or bosch
crank arm comes off as normal, lockring for the chainring needs a chain whip and (special?) lockring tool. theres a little o ring underneath the lockring i think that you need to get out before whipping the cog off.
