Can anyone please help? The right side of my popup stopped working. Got it apart and one of the pins had sheared. I replaced 3 pins, the 2 gears and the 2 plastic acme bolts. The only instructions it gave was "long spring goes on crank end". I did my best and now I am having to "lower" crank arm to even get the springs back up into the camper. Has ANYONE worked on one of these?
