Good question Tony

The mains caps are low in the block and difficult to lift out, the two claws on the tool are clamped to the cap, it has a web on it to claws cannot slip off, the other part on the tool is used as a pivot and placed on the block flange for sump, lever pushed down.........cap comes up ! If this tool is for the RR B range, then it is missing two items, a couple of specail screws for removing the rear mains cap, these screws have a large diameter knurled head and are screwed in to the threaded hole in top of rear cap, and claws are then able to pull out this cap. reason for two screws, one is BSF ( early engines), and other is UNF (later engines).
