All the suggested guitar tuners were crap. Most of them didn't give the HZ frequency or you had to put in a chord, then it would just tell you it was "tuned". The others were so complicated that it would give you a headache. All worthless.
Then I found this.
Only thing I can say about it is, its simple. Hold a mike to the belt, strum it and watch the Hz frequency readout.
If I remember, I set the belt tension frequency to 108Hz. There is a current service bulletin floating around the forum.
i use the 4mm horizontal cylinder, 5mm vertical rule.just replaced mine- were very tight from factory-as were the fasteners( I know about these, having snapped one!)
Technique is everything. Hold your thumb down on the belt with it deflected and then release. Trying to fly your finger past it like your strumming a guitar or flicking it will never work. You can tell when it is picking up the right frequency from the belt and not your finger, as your finger wont produce the 110HZ frequency. When you hit the right tension, the frequency becomes very stable. It takes a few trys. Of course when I decided to go and set my tension, by the time I got things apart, it started to rain, then the house airconditioner kicked on and seemed to run forever, the neighbors decided to start a cook-out on there covered patio that resonated there drunken jibberish straight into my garage. I gave up and waited for another day.i tried this and had no joy, all i picked up was the sound of my finger pinging the belt. I'd love to see some pics of the setup.
with the right belt tension what size allen key will go under the pully?
