Yeah I made sure that there was no slack in that span. I had to turn the crank backwards as you mentioned for the belt to grap the next tooth
YEP..... Never turn it backwords!!! Sorry SAM dose not show it done correctly. When the belt is held at the crank and the cam shaft sprockets are loosened!! (Yes you need to do this) the belt will slide right on.
I don't think you have understood, this is a very common technique used by professionals that I know as well. No one is suggesting rotating the engine backwards, and the cams are locked by the locking pins. If your using the hex key as the flywheel lock, there is enough slack to just back the crank fractionally, to grab the tooth.

Glend....O No I understand what some are doing and why. I believe if you are going to advise anyone as to perform a job on an engine like setting the timing! Your information should be correct! Just becouse its on Youtube dose not mean its correct. I know lots of people have done this and their Jeeps are running good. But done per the Wrong way leaves room for error.
The Timing system on the CRD is like several small engines with overhead cams that lock into position, permitting the cam sprockets to move during installation of the belt. These systems permit precise setting of the cams. The basis for the correct timing (precise) is setting the crank at a 90 degrees past TDC, Pinning the cams, Loosening the Cam sprockets and setting the pump timing. The service manual then calls for installing the belt at the crank, Using a VM belt holding tool (to assure the belt stays in the grove of the crank, I use a vice grip. Not to grip down on the belt, but attached to the crank with the tip of the pliers pressing against the belt so it dose not fall out of the crank grove) You then install the belt CCW over the Pump pulleys, loosened cam sprockets then the tensioner. No moving of the Crank. (even a tiny bit)
Now set the Tensioner with the sprockets still loosened. (most important) This places a uniform tension throughout the belt. Then tighten the Sprokets! This gives you the PRECISE timing setting of the cam's to the crank! Just like the VM factory did it.
Any other way you may have the timing off slightly. Will your engine run good? Sure but you may not have the best MPG and or power you could have had.
Sorry for the long winded reply, but i believe this is very important to show new people how to do it correctly.
Best regards
