    Not sure what this is called. Cutting a lawn today and heard what sounded like something break. After further inspection I saw this! It just broke right off. Mower only has 1000 hours and is kept inside.

    So my first question how bad did I mess things up? I can replace the screen, but you can see the plastic fins are a little worn from when the screen broke. Will it be ok to just replace the screen or should I take it in and let my dealer replace the fins also?

    Those fins are what moves air over your engine for cooling. I would replace them.

    Plus it throws off the balance of the rotating assembly. Strange kind of failure.

    Thanks. That's what I thought. Not sure how it happened. Everything was tight and I was in the open so nothing fell in the cracks. It wasn't rusted at all but is not in a nice tight ball of metal!


    The screen looks like and easy fix by undoing the 3 bolts. What about the fins? Just undo the center bolt at the bottom?

    I can't afford a few down days without the mower and I'm hoping the dealer has the parts in stock. For some reason they don't offer loaners when I have problems!?!?

    Those fins are a cast part of the flywheel. You may need a puller. Sometimes a rap with a hammer while gently prying up pops them loose.

    Uh no. The fins are plastic. They just sit on top of the flywheel and have some nubs that go into holes on the flywheel for alignment.

    Can't wait for a newer phone myself....grass is growing...won't be long..

    The screen breaking could be a secondary issue...
    See if you have any endplay on the flywheel...pry against the flywheel with a screwdriver...
