Mine broke on the press fit fan, it cracked and it's not a part that can be replaced. I have to take it to a local small engine shop to have them diagnose/estimate the repair cost to fax to Troy-Bilt to replace it.

What sucks is, some parts are not covered by warranty, and this part is. but if you really look at the warranty closely they barley cover anything!
The replacement parts that do exist are available, and it's not hard to take apart if needed. People do need to understand not to use regular pump gasoline with these engines - the small engines run much better and cleaner on non-ethanol fuel, like marine gas. I have ran small engines on marine gasoline for years and wow, no issues with gumming up, or problems with the engines. one of these little engines running on marine gas if properly maintained with oil changes per season I suppose can last a lot longer. mine ran fine for 10 years until the block finally cracked from corrosion formed on it.

Pretty nice, 10 years on a 4stroke that only died because I didn't keep the head clean of corrosion (I'll be monitoring that from now on)
