Do all school buses have a plywood subfloor

[o1marc]

I suspect there are other reasons for the plywood, such as sound deadening, insulation, better material to bolt seats to, etc. I doubt it is intended for added structural strength, even though it might.

Well I spoke too soon. Decided to pull out the seat and the rubber mat below it today and lo and behold there's some disgusting and wet plywood. Gonna be a project getting it out because or poor access to the footpedal bolts.

I made the decision early on to stop the demolition at a line about two feet behind the driver's seat, where I'm going to be building my insulated bulkhead wall. My bus fortunately seems to have been parked nose up most of its life, so most of the rust is in the back half.

Seems like you need to keep going, though.

I haven't decided yet. I have a front engine; got plywood up to that point. The floor is raised under the driver's seat and still has rubber down. But the seat base is pretty rusted so I assume it's bad underneath. But dang that's going to be some work to pull everything out.

yeah honestly the more I look at it from the underside the more i think i should just stop at the pedal. there about 7 bolts holding down the 2 pedals and i can only see about 2 from the underside and they're inaccessible from the top. I don't see how i can get it out or get it back in

Hey all! Was just wondering what screws you recomend? Kinda following Johnny Mullets floor. 1/4 foam and 5/8 plywood. I know there seems to be some question as to whether or not it should be screwed down at all, but is we wanted to, what screws would work in the 16 gauge sheet?
