So I took off the balance shaft sprocket to change the tensioner because I couldn't get the bolts out of the tensioner mount. The sprocket is funky looking it has half a key in it that doesn't engage with the keyway on the sprocket. I'm assuming that this setup is just like the cams where the timing chains position is irrelevant as long as the balance shaft relationship to TDC is correct. Has anyone messed with these before? If so what's the story with the funky gear who's key doesn't engage the shaft.
Did you get this resolved? The balance shaft crankside gear is keyed to the crank with a larger key behind the smaller keyed gear 2000StreetRod is showing.
2000StreetRod, thanks for fixing my error, completely forgot doing the balance shaft timing step.
