I am wondering if the flywheel on a sportsman 500 2000 is pressed onto shaft or does it have a keyway? I cannot get timing set right looking through timing hole. Can i crack that case just to take a peek?
the flywheel should have a tapered fit and woodruff key also...the fly wheel presses on when you torgue the crank shaft end nut....the key keeps it in the right position and from turning on crank with rotation of engine
They have been known to sheer. Remove the case side cover and remove the flywheel nut, you'll know soon enough if the key is gone.
With age ,it does get a lil difficult to see the timing mark on the flywheel, sometimes just removing the side cover is all thats needed to be able to see the TDC mark.
