Following my thread about radiator removal to get into the timing cover, I now own a new cam sprocket and timing chain. The new sprocket is unmarked. The cam and crank are in the correct positions (aligned timing marks with #1 TDC on compression stroke). I want to mark the new sprocket off the old one. To do this, I have stacked the sprockets, put a snug spindle in the center holes, dropped 4 bolts in the holes and jumped 1 bolt hole at a time until the teeth on both sprockets are in perfect alignmment. I then pen marked the new sprocket at the mark on the old sprocket and when I test fit the new assembly visual alignment is correct and the cam sprocket bolts thread right in without moving the cam. The question arises because when I turn the new sprocket over and repeat the spindle and bolt insertion process, I find that there is also a place 3 teeth over where the sprocket tips seem to correspond exactly and the dry fit also aligns perfectly with the bolt holes in the cam. There are 42 teeth and 4 bolt holes on the sprocket and 2 bolt holes in the cam. I feel like, if I had not dropped trig (or had not been sitting next to Tammy in geometry), I could figure this out, but does anyone know if there indeed is a correct position on both sides of thie sprocket.
