Restoration of Elevation and Traverse Operation (cont.):
Shown is Thomas Podnar at the work of removing the main drive shaft for the elevation of the barrel. The shaft and its bearing where it penetrates the cradle wall was thoroughly corroded making its removal a very difficult task. The bearing in the pillow block supporting the end of the shaft was damaged by corrosion as well.
Fortunately, modern bearings were available that fit perfectly in all instances.
