Dear Ladies and Gentleman,
the old wear wall are no longer available.
The new wear wall has the same external dimensions.
Only the 3 holes in the middle line ( yellow marked in the attached file) are displaced by 17 mm ( old = 270mm ; new = 253 mm)
There are three possible solutions.
1. suggestion:
You have to close the old holes by welding.
Then you have to drill the new holes 17mm above and 17 mm below the old holes in the middle line.
2. suggestion:
You buy from us a device for drilling.
3. suggestion:
You order a field service technician.
