CR9080 combine concave

[Gone Shooting]

Whilst on grass seeds a large lump went through breaking the concave shearbolt ( rotary combine ) - replaced shearbolt but as it slammed down it seems wedged and wont pull back up. Tried under each side with some jack pressure but still not budging - any tips please before we bend something - thanks.

Check the slide between the 2 concaves. I had one jump out of the slide on linseed once. It broke a weld off.

We had exactly this aswell on our old 9070

Done this also, out of action for over a day. Tried jacks pushing from underneath but when you look at mechanism in tank through the nearest cover to the front you can see the metal wedged in almost like a double hook. Only way we found was to use a sabre saw and cut each side to release the mechanism. Once free weld a 10mm rod onto each side of the vertical sliding piece to stop it ever happening again.

Sorted - 2 jacks and a sledge hammer - winter job
