I have a problem where the manually wound activating arm has broken. I can see by the Reimo site on UKLeisureParts that they are handed but have been informed that they can be flipped. Has anybody had experience of this? It looks to me from the picture that I could possibly reverse the locking nut and bolt. This is the link to the part that I'm writing about.

I have a Reich move control and the near side arm has stripped its thread. I found a replacement on Lesuire Shop Direct with expected delivery end of August. There are two different parts numbers so I don’t think they can be flipped. There is an exploded diagram of the parts on LSD’s website.
I can’t see the link to the part mentioned in your post.

This is a link to the page with the diagrams. Click on ‘caravan movers’ then ‘view exploded diagrams’
