Hey evrybdy!

My belt deflection is 32mm so i guess it needs adjusting from what ive read , the question is should i replace the belt or leave the same one? It has only like 10 hours ......about the shims, i ve read it has to be removed or added in order to get the recommended mm's in belt deflectión, now can someone add a pic of what a shim looks like....and where can i get them, plus in order to decrease the mm's should i add thin or thicker shim's ....spare all of my questions. Thanks in advanced
