I think it's a 30K mile service item, but I'm not sure. I go 50K and replace with a top quality belt like Gates or better. Not the junk from Checker or Auto Zone like stores, I get mine from IH or a Napa in a pinch. I also keep a new one and tools in the truck just in case I pitch one, I live in Alaska after all and I can be over 200 miles from a parts store.
You cant tell by looking at it when it's gonna go. I have had new ones shred in 100 miles and had one all cracked and strings sticking out on my fork lift that went 10 years and out lasted the motor.
