What you're measuring is the amount that any chosen spot on the chain moves up and down.

So, bottom of chain to bottom of chain, top of chain to top of chain, center of chain to center of chain ... your choice.

Success

Chain's tighter (hopefully not too tight).  I'm pretty sure it rides better.  Rolling on the throttle seems smoother.

Next I may try changing the oil myself  

Thanks Kerry for your help!

I just adjusted my chain for the first time this afternoon after agonizing over whether I would do it right or screw it up.   I followed the repair manual and it took a grand total of about 5 minutes to do.   It takes VERY LITTLE adjusting to take the slack out of the chain, so watch out for over-tightening.  Lubed the chain while I was at it.

does anyone know the specs of a bad chain? how many links is it per unit of measurement?......I think my chain is stretched to the point of needing replacing..


I guess my snap-on 3/4 drive torque wrench will do it's lowest setting is 50ft/lbs...got to love them big trucks I work on 200ft/lbs +some sweat and heavy breathing
