Motor mover cross activation bar

[SilverSurfer]

My caravan is fitted with the standard Powrtouch Freedom mover with the cross activation bar.
I went to move the caravan from the side of the house, put the handle on the hexagon and located the roller onto the wheel ….BANG …. the cross activation bar sheared.
The bar is approx 10mm diameter and would seem impossible to shear by a basic turn of the standard supplied wrench.
Luckily the component appears to be easy to replace and I can activate the movers independently.

It’s usually the pins going through to connect the break. I replaced them with cap head screws with a locking nut on the threads.

Not if it’s a roll pin that has snapped through corrosion

Ours sheared many years ago.
Counted it as a blessing in disguise as it was a pretty hefty piece of metal. Sold the bar for scrap and allowed a few more kgs of payload, win win 👍

I think these stress breaks are caused by lack of lubrication on the mechanical pivots causing excessive strain on the bar. .
