On the Iphone you can use Omnituner or another tuner that lets you view the frequency,
or you can tune to the piano equiv. of A2.

Here's a reference tone - http://www.youtube.com/watch?v=YHJtpHftzkI

Next check the freq. of the exaust. Paso - the other musical instrument ;)

The "factory tool " is nothing more than a spring balance scale ( sorta like you'd weigh a fish on ) with 2 marks on it that line up when the correct tension is reached . The idea is to hook said spring balance ( or preferably any other with kg's marked on it ) to the post in the center of the tensioner pulley and pull till you have a reading of 10 kg and do up the tensioner bolt , a lot of fuckpotting around .... I just use the allen key method.
Another thing I did was to hook up a timing light ( any cyl will do as timing has nothing to do with this ) and aim it at the slack side of the belt ( tensioner pulley ) and give the engine a good rev and you can see if the slack side of the belt is starting to flap about . This proves nothing other than I was bored and don't nobody use this to tension their belts , more of an observation than anything

5/6 mm. allen key! The easiest way to tune the belts.
No esoteric method.

5/6 is too easy ;)

All the tuning nonsense proves that manufacturers must invent a complicated method to do something
just to appear professional.


That said, it would be nice if we had an inspection window.

Yeah that and to sell unnesessary service tools
and speaking about appearing professional ... have you guys ever been in the pits at speedway/stock car racing ( at least how its done in NZ ) a bunch of oafs clomping round in "see you en tea" kickers (steel cap boots) and (stolen from work ) overalls bashing their chasis straight(ish ) with a sled hammer or welding on another bit of railway track.... to hear them talk you'd think they were F1 technicians :D :lol: :lol:

I followed the instructions using the 5mm and 6mm hex wrenches to verify belt tension and it worked perfect. I have the retainer rims on my belt sprockets and removal/installation was easy once the tensioners were fully loosedned. I removed the spark plugs and put the engine in 4th gear and rotated the rear wheel to align the sprockets before I took the belts off. All in all a very simple job to do. Thanks all!! :thumbup:
