My friend, do not complicate the life so much, remember that you talk about the brands, well, you have your own brands, if you want you understand? If you do this three times by pulley, the strap will keep 9 different brands, then you delete them if you want no problem, after doing this, the belt uncovers and take it out, the new belt is the brands it is actually just like the one you took, that is, you take a tooth of the belt and you paint it or brands, then you tell how many teeth of the old strap ahy to the next brand, then the accounts in the new belt. And so until the 9 brands are completed, so when you put the new belt, you will calm the brands of the new belt with those that were left on the pulleys, tense and now, the kango will stay the same as how you had it, it is a fast shape and cenchal to perform, then when you tense the belt, just do that the side of the fixed distribution (the one that does not have the tensor. Brands only follows the brands and now) the tensioner can be tightened in several ways with a screwdriver or a lever there is no problem in that, just make sure that the tensioner is well placed where you have to go, you should have help for this operation you have to tighten the tensor screw while keeping the belt tense.
