[Bolens 1000]

I was mowing with my bolens 900 with an s-8d wisconsin engine and heard a noise so i got off and saw that the flywheel had came loose. any reasons why this happened or sugestions on what to do , i was thinking that mabye get a new lockwasher or use locktight to keep it in place. ...just seems strange that after 2 years of it being last put on it would come loose now.

There should be a thick belleville washer under the flywheel nut.

there is a washer there but it looks worn out i'll order a new one and see if that helps, thanks

I replaced both the nut and washer on the flywheel and it seems to be working fine
