I guess it depends on if the cross head and or chassis is damaged.
I presume it must a write off to end up where it is.
I agree 100% John , if it is an insurance write-off then I am sure that it will need a new chassis, new crosshead plus a whole lot more) in parts.
The big cost here is going to be the labour, great if you have the experience, knowledge and space to tackle this, but it won't be commercially viable as a project if you have to pay someone to do it for you.
