I made a very nice 165 mile ride today. The weather was great with temps in low 60's to 75 in the afternoon, just a great riding day. After returning to my home I gave the 2016 TGU the usual walk around and inspection. When I looked under the rear end I immediately noticed something wasn't right about the belt. The belt has a "groove" cut in it about, 1/4 inch wide and a good 1/8 inch deep, running around the entire length. I am enclosing a picture made from the left side to illustrate the problem. I have not had the time to jack it up where I can see a little better, but I can not find anything visually that could have caused this. I first thought it might have been a rock that was thrown up and lodged somewhere, but there is nothing to indicate that. Also, if you look at the picture it almost looks like someone ran a drive belt around two pulleys, spun it and used a chisel, or something similar, to cut a perfect 1/4 inch wide channel in it.
Now, before anyone ask me this question, NO, I did not hear anything unusual during the ride. However, I do have a hearing loss and wear a pair of the small hearing aids, mostly for the higher frequencies. When I am riding the hearing aids are not used, but I ride with a high quality pair of ear plugs that block a lot of noise. This is the result of previous hearing loss from C-130 engines and years of shooting. I always tried to wear hearing protection but obviously it didn't totally work. So, whatever cut into the belt probably made some noise but while riding I just didn't hear it.
I will jack it up tomorrow and have a better look, but there is not doubt in my mind....the belt has got to be replaced. Depending on what caused this, it may or may not be covered by warranty. I have not done any kind of work to the bike that I feel could have caused this. I installed a new head pipe, mufflers and AC system shortly after I bought it. I also installed a DK oil cooler and filter relocation kit that all works fine and absolutely has nothing that could cause this. There is no signs of any oil leak or any other damage that could do this.
Have any of you ever seen anything that looks like this before? The rear end and basket all look fine, no loose bolts etc. I can't see the front sprocket real well until I get the trike jacked up, but from what I can see with a good flashlight looking at it from the rear, it looks fine. Anyone know what a HD shop gets for changing a belt on a TGU? I know "it ain't cheap". HA HA
I apologize for the big picture, should have made it smaller before I uploaded it.
