If I were you, I'd buy two and just replace the one now while it's in easy reach instead of waiting for it to break mid-job. 5 minute job next to your shop, or an unexpected break and walk back to the shop for a belt and tools (assuming you notice in time to avoid an overheat)!Thank you for that report! Mine has 520 hrs and is 5 years old so I’ll grab a belt as pictured.
