As I was doing my first oil change, I just completed a teardown removing all plastics including plastic a arm guards. Washing everything and then making sure all nuts and bolts were tight. After reassembly I have two plastic push rivets left over and one smaller bolt the size of the ones that go into the a arm plastic guards. What I'm assuming is that I put two metal bolts with washers into a spot where plastic rivets should have gone. Although I'm not really sure. Anyone have any links to a video or pictures on removing and reinstalling plastics in detail?
