I checked again, I am using the right belts. Bag #4 is still intact. Come to think of it if I use the wrong belts the front would be way loose and the rear would be tight. This is not the case here as it seems that my front belt now is a bit tight.
I also checked the bulkheads and the cam marks are on the outside.
I loosen up the bulkheads, the motor mount, top deck without the the front and rear axles in place. No matter how carefully I fasten them the chassis would warp. Also the front I had to move the cams from the central position so that the belt tension is right. Still the chassis is wrapped, and I was mad.
What I finally did was to twist the whole thing the other way from the wrap. Curiously I found something slipped as I did no, and by chance after I twist it the wrap was fixed! I had a flat chassis! I then check the screws again and they were tight. Brute force finally did it for me
