I agree with redistributing the slack after the new belt is on but that is not what is written in the last paragraph of 8.4. Here is a quote from the last paragraph of 8.4.
"I also recommend getting a good manual (Chilton's or the factory manuals) to assist in this process. Be sure to set the engine to TDC -10 degrees (as outlined above)
before removing the belts. In addition to the two reference points mentioned above, there are also alignment marks on both of the balance shaft sprockets. Make sure that everything is aligned
before removal. Once this is done, R&R the belts (or go further & replace the tensioners/rollers if you are doing so at this time). When replacing the belts, make sure that you keep the reference marks aligned! Being off on the camshaft sprocket will result in valve damage; being off on the balance shaft sprockets will result in much vibration from the engine."
Too me, the second and fourth sentences contradict themselves. The second sentence says TDC-10 before you remove the belts while the fourth sentence says to align everything before you remove the belts.
Confusing to me but I am easily confused.
