3. Place the uniquely colored link so that it lines up with the timing mark on the intake side balance shaft sprocket (2).
4. Working clockwise around the chain, place the first matching colored link in line with the timing mark on the crankshaft drive sprocket - approximately at the 6 o'clock position on the crank sprocket (3).
