Step 11: Removing the T-belt
Hand turn the crank until the I and E align and the crank pip/keyway aligns with the notch on the block. When I say hand crank, I mean put the crank pulley bolt in and turn with a wrench. At this point, you'll probably want to remove the spark plugs so you don't have to deal with cyl compression forces. Remember, you will have the belt on at this point. If you are going to be using the same belt, mark the direciton of the belt with a paint pen or sharpie (never reverse the direction once installed).
This is not too bad, but it is under a lot of tension. First find the correct hex key. If you are changing the tensioner pulley, find something that fits it. These instructions are not the same as the manual, but it works well. First loosen the tensioner pulley bolt. Using your hex key, turn the tensioner to the right until the spring has the least amount of tension on it... Then, reach down and pop the spring off the hook pin. You should have this (plus the belt):
