Stronger belt for Comet 30 series?

[sse1478]

Hi guys,

I just got my new 1 inch bore driver for my 13 HP engine. I believe that it is a larger diameter than my old 3/4 inch bore driver. I am concerned that my new larger driver combined with my bigger engine will put a lot of strain on the belt because the driver will try to pull the belt away from my 6 inch driven unit thus, forcing my driven to expand much farther than it currently has to. I know this will cause my kart to go faster because the gear ratio will be changed. My concern is that this increased drive ratio will try stretch my belt and put a lot of pressure on the sides of it and create a lot of heat and wear. My current belt is an Manco 5656 and it is not worn at all. Is my theory correct, or am I just over cautious? This brings me to my next question, are their stronger belts available? If so where could I find them?

Is the new driver a Series-40? If it is, then you need to replace the Series-30 driven with a Series-40 driven and get a Series-40 belt. Take some pics for us so we can see what the issue is.

The new driver is a 30 series, just a 1 inch bore instead of the 3/4 in bore. I just want to know if my theory is correct and if their are stronger belts for the 30 series.

You have to make sure the distance between the pulleys is what
the specs call for. This means you may have to adjust this distance (center to center). If this is correct there should be no
worries

Are you sure the driver pulley is a bigger diameter? I was under the impression that they were the same size and just the bore was bigger. Here is the belt chart to compare your measurements with http://www.gokartsupply.com/beltchart.htm the larger engine might have effected the distances between the two shafts you might have to go with a longer belt, I don't know of any stronger belts for the 30 series
