how do you go about sorting the timing if you've got aftermarket pulleys that don't have the mark for timing light?

with great difficulty, what you will be best doing, and i know your not going to like this, but pulling the after market pulley off, getting a OEM one, sticking that on, doing the timing, taking that one off, using the OEM one to mark up the unorthodox and putting that on, then rechecking the timing to see if your mark is correct.

noooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo.:scared:

Can't you just measure the position of the of the OEM one and transpose that on to the unorthodox one?

diameter is different as the unorthodox is smaller, would be best lining it up when both are off the engine.

How does that work?.... wouldn't that change the amount of turns on the cam?

nope, the cam belt sprocket sits behind the pulley, the pulley with the timing marks on, just drives the power steering, fan, AC and alternator.

 

If you measured around it, you would be off, but as the pulley is still turning the same speed as the cam, a new mark on the light pulley in the correct place will still give the same reading.

 

hope that makes sense lol
