Well this weekend while cranking up my Tent trailer the secondary Crank (trailer has Posi action 2 cranks)which connects to lower middle Posi crank, seemed to have sheared a pin or stripped. Happened when Tent trailer was fully extended. Didnt hear a snap and all cables still intact.

I was able to use the Main (middle lower) crank, which is connected to main threaded rod. I have read that this is a common issue for the top left Crank to shear the pin .

Has anyone dealt with this? Its only a $5 part but I have no idea where it is or how to fix...

Crank that just free spins now is Top left in first pic (connects to lower middle one)

Get someone to turn the upper handle and see it the lower chain gear is turning on shaft if is the shear pin in the main shaft is sheared
If it don't turn then it's the pin in the upper you will probably need to remove panels to acces the upper one good luck
