Hey @Caladinho , sorry for the delay. I left the beds bolted to the tracks but I had to release the tension from the lower bed in order to have slack in the chains. I did this by setting my dinette table under the lower bed so it was raised up some from the stops. It ended up being a super pain in the butt to get everything timed properly so taking the beds off might have saved me some time.
The motor assembly comes off from the inside of the upper track which is bolted from the top. The side tracks stay bolted to the walls.
