ive only done a timing belt 2 ways on a honda.
a) use the timing belt tool (you can get it from honda or snap on, but both are WAY too expensive).
b) use an impact and pray.
usually b takes some time cause that nut never wants to come off, and then when it finally does come off.....how are you going to get it back to the right torque.......thats the question that has plagued back yard honda freaks for years.
my advice is go to the dealership and buy the tool if you want it done right (i even broke down and did it).
