The only difficult bit, imo, is knowing how tight the belt should be!
The guide I used said that it should be tight enough to just run a 5mm allen key between the belt and the tensioner pulley on the horizontal cylinder. I had a practise on the belts before taking them off to get a "fell" of this, and sure enough I couldn't get a 6mm allen key through but I could a 5mm key.
On the vertical you use a 6mm key, and again it felt the same as using a 5mm key on the horizontal.
There's also the "twist" method, where you should be able to twist the belt to a maximum of 45deg at the mid-point between the tensioner and the cam pulley. I also checked this and it seemed fine.
You can also use a sonic method - "strum" the belt and see what frequency it is. The tighter the belt the higher the frequency. Unfortunately I couldn't get consistent results with any of the microphones I could find!
I don't have a tension checker, so couldn't test that.
Having a cam locking tool should make things a lot easier on my 748, and luckily I have quite a few of those knocking about
