Here is a tutorial on which orings to replace on an Autococker ram. I cover the disassembly, oring replacement and reassembly on both a Brass WGP Autococker ram and a later aluminum model.
To disassemble your WGP Autococker ram please view this video first:

After breaking the loctite on the ends of the ram you can disassemble and replace the oring.
These orings work on a classic brass ram and may work on a new style WGP ram as well.
