Do you have any photos of the X configuration 24 cylinder engine that was built for aircraft use but apparently never used? I understand that there were two made and much like two V12s on top of one another.

Don, -> this way, please. A decade ago we took a -> quick look at these machines. Anyone who gets a taste for it will find something -> here and -> there about the practical use of the engines.

Thank you! That’s more than I had hoped for after having seen a photo pop up when I was traveling recently. Interesting that the crank has no main journals as such but rather uses the bore to do it.

The "X" engine, from this Packard publication, I'd be glad to post the pages on the other motors if there is interest.

The "X" motor is also given coverage in Bob Neal's books on Packard motors.

Don, you'r welcome. Enjoy PackardInfo.com!
Dave (O_D), thank you for giving us insight into your treasure chest. The factual knowledge from experts like you, coupled with friendliness, is what sets PackardInfo apart from sites that contain nothing more than a series of images.

Imagine the infernal noise created by dozens of roughly riveted leather transmission belts. The dull rolling of the large ball bearings, the beating of the fluttering belts, the howling of the shafts and spindles while the heavy spokes of the cast iron flywheels blow the warm downdraft from the friction surfaces through the hall. And all of this rotates at different, but always high, speeds and does not stand still even at night. The eye cannot find a quiet spot to rest. Everything signals danger. Woe to anyone who gets their arm caught in it.
