There is a pin in one of the sprocket holes.
Put the nut back on hand tight.
Rotate the engine to TDC.
Remove the chain tensioner.
Take the nut and wave washer back off.
Use a spark plug as a tool (remove the threaded connector) to pull the pin out.
Chain is now loose.
Remove sprocket.
I had tried all of this with one exception- I did not necessarily have the engine at TDC. Why does it need to be at TDC?
I removed the nut, chain tensioner and the little pin. I thought that the sprocket should just slide off the camshaft however mine is still on their very tight.
