"Next, use a 17-mm socket to rotate the crank pulley by hand. This will make it easier to realign the new cams once they've been installed. The idea here is to bring the Number One cylinder to TDC on the intake stroke (not exhaust)and this is identified by the "UP" markings on the cam gears.You can be sure you're precisely at TDC by lining up the lone white mark on the crank pulley
with the timing mark on the lower timing belt cover "

Does anyone have pictures on the crank pulley being rotated? Im not sure which pulley is the crank. thanks.
