How do you do the bolt tightening math ? e.g; 52 ft. lbs, 18 ft. lbs

Are you asking about how to torque bolts in steps? (e.g. For tightening head bolts, etc.)

On the manual (link below), it tells you to torque the camshaft bolt to 52 ft. lbs. And how do I know/measure tightening the bolt to 52 ft. lbs?<ul><li><a href="https://forums.audiworld.com/12v/msgs/572.phtml">DIY timing belt</a></li></ul>

You use your calibrated elbow or a torque wrench...

You'll want to use a torque wrench and set the calibration to the torque you need. The camshaft bolt neds 54 lb-ft. of torque (per MikTip's diagram). So you'll set the torque wrench to 54 lb-ft. and will push down on the handle gently until you hear a click. This is where the torque wrench will give you an audible warning that you're at your torque setting.

I like to hit the same nut 2-3 times with about 5 minutes in between torquing. (Head bolts, I wait 1 day) This way the bolt will relax and you can re-apply torque to make sure the bolt will hold the torque setting.

I hope this helps!
