Re: Yamaha F150 2006 Timing Belt

The question was how you take the tension off the belt, or reset the tensioned pulley.
Thanks
The timing belts on Yamaha 150 4-strokes use a hydraulic type belt tensioner. It is non-adjustable. You release it with a allen key and a stopper\holder tool which will keep it in a relaxed position. If you get to aggressive and impatient with the allen tool, you will strip the area that the allen tool sits in.
When this happens(as the thread starter has probably unfortunatly learned) you will trash the tensioner and it will need to be replaced. When you try and release it you need to put pressure on the allen tool in a slow type movement and wait for the tensioner internal cylinder to collapse .
The spring type with bolt is used on the HPDI belts.
