Mystery Solved....

As many suspected, I had mounted the scissor jacks to the floor ribs. The pressure this put on the frame over 5 months finally caused the damage you saw in the pics above.

I lowered the jacks and the bus settled almost back to where it was. Hopefully the body damage was minimal

Thanks for all the feedback!

I would suggest taking a close look at the clamps that hold the body to the frame. I would expect that they were bent and now are resting on top of the frame rails instead clamped under them.
Best to get that fixed.. It's serious business

Do you mean the clamps you see here?

Yes, that's a different style than on my Thomas, but those are holding the bus body to the frame. Are there more clamps closer to the bumper? Those are the ones I'd expect to be damaged. Look closely, because it's possible that the bolts pulled through.

I haven’t moved my jacks since the “incident” started pulling the frame apart.

I’m still confused about where these leveling jacks should be mounted. I took some pics under the bus.IMG_4964.JPGIMG_4965.JPG

Could I move this one rib closer where the floor joist seems to be properly secured to the bus frame?

Best of luck pardner.

The only way to correctly do it is to attach the lift directly to the frame or possibly to a heavy angle bracket bolted to the frame.
I don't know which eaz=lift you have but, their biggest is only rated for 7500 lbs and I suspect that is for a pair which is how they are listed in the catalog. Even if it is each, if you are trying for any lift at all, your rear engine bus is way over that.

I’m not sure how regular everyone do it but some of the older coach even have a pretty massive crossmember across the front a d rear .. important that it goes all way across so you don’t twist the frame when jacking.. you want the suspension in play .. you aren’t trying to lift the wheels just level the bus and stop the wobble of the driving suspension. You want your jacks outboard as close to corners as you can so I’ve seen essentially a subframe crossmember used for the jacks.

What is considered "Frame" here? The main steel running lengthwise down the bus is too far in the middle.

thats is the frame.. if you crawl under you'll see that this wjere the bus body attaches to the chassis.. the cross "members" are the floor ribs and are part of the body and not the chassis. lifting the bus from anything other than eequipment attached to the chassis will tend to separate the body from the chassis.. the body isnt designed to have the chassis hanging from it..



you can Jack the bus on its suspension around each wheel.. ie lift near the spring as that is chassis component.. not enough to pick up the wheel.. but im guessing you'll park somewhere at least somewhat level?
