I use the trail tech temp sensor. The belt runs from 140 to about 170. In hot 95 degree weather it takes 10 miles of loose deep sand wash to get it to 185 degrees. Belt life will be very good, the glue melts at about 260 degrees and belt wear is increased at 200 and above. The Yamaha doesn't need a belt temp sensor unless you have huge tires and do lots of very low speed driving. I do some difficult rock crawling. We use a spotter in some areas and rope the front end to a couple of Big Guys up the hill so we won't loop out or slip sideways if one rear wheel spins out.

a mod worth doing as I also do a lot of low speed crawl.

Great information Bob! I always wondered about the effects of heat on the belt. I must get one of these!

For those interested we offer a Belt temp gauge kit. We designed and use this gauge in all of our race cars. It is an invaluable tool to help prevent belt failure.

The Alba Belt Temp Gage is a much nicer unit and it is easy to read. You can see on the Alba gage running in the yellow section will increase belt wear, I like to stay below 180. My stock Teryx would run a bit over 200 after 10 miles of deep sand and mostly WOT. Large tires will increase the belt temp and a gage is necessary to avoid belt failure. Nate has way more experience especially with large tires and can add or correct any of the above info.
