NOTE 1: The Lister and Argosy connecting rods are very similar, differing in the material from which they are made (Argosy = bronze, Lister = cast iron), the width of the big end (the Lister journal is approximately 0.1” narrower), and the size of the small end gudgeon pin (Argosy 7/16”, Lister ½”). The Argosy con rod small end and crosshead would need to be bored out to accept the larger Lister pin.
NOTE 2: The Lister and Argosy plunger rods are both 3/8” diameter, BUT the Lister thread is BSF and the Argosy is BSW making all screwed components including the crosshead non-interchangeable unless remedial work is carried out to correct the difference in thread pitch. A complete Lister con rod/crosshead/plunger rod assembly would fit the Argosy as the assembled lengths are virtually identical, though a degree of side play in the connecting rod big end would need to be accepted or remedied.
NOTE 3: The Lister gland assembly is of different design to that of the Argosy, but a complete gland assembly would probably be interchangeable between the two pumps if the old one can be removed.
NOTE 4: The Lister leather plunger cups are the same outside diameter as the Argosy parts, but have a smaller centre hole. Lister cups could probably be opened out with a wad punch to fit the Argosy plunger assembly.
