I'm trying to complete a timing belt replacement and have run into the following snag: When I've got the belt and tensioner on with both crank and cam lobes in the proper positions, I end up with a little slack -- maybe a couple of degrees -- when I rotate the crank by hand. A friend of mine who's helping -- and says he's done the job several times -- insists there should be absolutely zero slack, that the cam should move at the same instant as the crank. Is this correct? I've checked a couple of online "how-to's' and haven't found any mention either way.

Are you aligning with the timing cover marks or the notch near the crankshaft?
If you look at the crankshaft cover (the PITA around the timing belt) you will see a notch. Use that notch instead of the crankshaft pulley, you will have an easier time removing the slack.

Exactly. Did you let the tension spring put the correct tension on the Tbelt and then tighten the tensioner in that position?Originally posted by Dave View Post"If the sky were to fall tomorrow, the tall would die first."

It shouldn't have any slack...Your signature picture has been removed since it contained the Photobucket "upgrade your account" image.

+1 zero slack. Make sure you let the tension up on the driver's side, not the pass.1989 cirrisblau-metallic 325iComment

This is why you need to make sure and NOT follow the Bentley; it is clearly wrong.Originally posted by SpecM View Post
Try it my way and you will see the obvious logic behind it, plus the tension will actually make sense.
