7afe timing belt help Options

[Hanyo]

anyone know the 7afe timing belt alignment marks and have pictures of them?


I know your suppose to set the crank at 0 degrees TDC on pistion number 1 but where is the camshaft pully marking?


I just did the timing belt on my 7afe and now i;m getting a knocking sound around 3k rpm. Its idles smooth and starts easily. My timing is at 15 degress when its suppose to be at 10. I cant adjust it either because its OBD2 and the ecu controls that.


I'm thinking i jumped a tooth on my timing belt. Anyone have an idea whats could be wrong?

the mark is a little U mark on the head that will be visible through the hole in the cam sprocket.
but its like really hard to see cause its right up against the body.
when I did mine I first put it on with too much slack on the outer side and too tight on the tensioner side.
so when the tensioner was released that part got tight, but the other side wasn't and when you turned the motor over it took up the slack but it was off a tooth.

You can however adjust the timing with just taking the top half of the cover off. that way you can leave the crank pulley/balancer in place and look at the timing mark on it.
Turn the motor with the crank bolt until the cam mark is lined up, then loosen the tensioner and take the belt off the Cam pulley.
now pull up on the exposed ends of the timing belt and use that to line up the mark on the Crank pulley with the mark on the outside of the lower cover.

what I actually did was take the crank pulley back too far just about a tooth, then I slipped the belt on so it was nice and tight on the outer side, and then used the crank bolt to turn it forward just that one notch
so the timing mark on the crank was dead-on. then you can let the tensioner go and it will be perfect. After you tighten the tensioner use the Crank bolt to turn it over by hand TWICE, and be sure to check the marks again
before you decide it's good and put it back together. also before I took it apart I marked the cam pulley and the side of the head with my nieces hot pink nail polish so that I would have another really visible mark to double check by.


this thread is for the 5sfe but it has some good pics of the timing marks and yours will be similar.
