Piston expanders

I sometimes see unusual Hudson items on Ebay like the following. Not interested myself, just curious if they work and how they work. 110207761163

1948 & 1949 Hudson 6 piston skirt expander set. Genuine CAM-RITE expanders # 30. The box states that these fit all 48~49 with 3-9/16" T-slot type pistons. This was a common fix back in the day for sloppy piston fit. These spring steel expanders can be installed WITHOUT removing the pistons from the block, no piston modification needed. Used with cast iron, steel, or alloy pistons. Thanks for all replies, Barry

    Sounds something like the proverbial left handed monkey wrench or a can of two-way radio squelch... :D;):eek:

    All they do is break the piston skirt and there goes the cylinder walls. Walt,

    I'M with Walt on this one , that skirt is MIGHTY THIN AND BRITTLE , and an over bore needed because of scored cylinders on these ebgines is not something you want to do unless you have no choice . BUD

    The piston expanders are from the days back when if you got 50,000 miles out of an engine you were doing well. Engine rebuilding was a major industry, for every 10 million cars on the road, 2 million engines needed rebuilding every year. Every small town had an engine rebuilder.



    There were a lot of gimmicks back then trying to persuade mum and dad they didn't need to spend all that money on a rebore or new pistons. Cord rings is one that comes to mind, they could successfully run (allegedly) in a bore worn 10 to 15 thou.



    The piston expanders were another 'save money' idea.



    They would be a nice novelty item to have among a collection of Hudson trivia though.
