I'm working on getting the timing chain and timing in general set correctly. My issues is when I got down to the crankshaft sprocket (special nut), this is a left hand threaded nut that when I went to check it with my hand, i was able to loosen without much effort at all. I grabbed it with one hand and simple started loosening it. I have checked my service manual but I can't find anything about any torque specs on the 'special crankshaft sprocket nut' in there anywhere. I do remember seeing something on Partszilla video about the guy mentioning that it doesn't have to be 'tight' as the rotation of the engine 'tightens' as it needs due to the reverse threads. Now, I need to know the proper tightening procedure for this. I have attached an image to show the nut in question.. Thanks in advance for any help/information.
