Ok, so i now have 7 of these machines dating back to 2013. The two newest ones i have have what appear to be aluminum idler pulleys with aluminum caps (instead of the brass colored ones with the black plastic/rubber caps). I've had a few failures to date on my older units and sounds like another is going bad. Seems like the caps crack and open up and then they eventually fail.
From the exmarks parts manuals and some research, it looks to me like there's been at least 4 revisions:...
