Sorry about that but I did not want to potentially mess up BostonBulls post.
We know that the early 575's were prone to bearing failure and subsequently
failed/melted causing a rebuild under warranty. I have it on good authority that the serial range to ID the problem bearings were from start of production to the first four numbers of the serial number 05.12-----. Anything after that has the new bearings and should be OK. Turns out Bulls saw is in the
shall we say, the good serial range above the 05.12----- cut off.
I have a 575 myself and was concerned so I looked into it and hounded Husky until I found that out. I am not a dealer or an expert just a guy who wanted to know about his saw and any potential problems the factory had knowledge of. Again Bulls saw is good according to his number!!!!
