Alright, I am in the middle of changing the engine sprocket, have a breaker bar, all I need is the right size socket to get the nut off. What size do I need, called my local dealer they said they think its 32 or 36mm. How can they be unsure?! They work on the friggin things. Anyways, anyone privy to this knowledge? Also, where do I find such a size? My local home depot and lowes suck and dont have anything bigger than 27. Thanks for the help.
