Air sea rescue

Is it true the L12 was the basis of the engines used in U.S. PT boats? Trekphiler 06:04, 16 May 2007 (UTC)[reply]

Name

Is "Liberty" the name of the engine or the manufacturer? If engine, shouldn't the article be titled L-12 Liberty? Drutt (talk) 19:29, 23 April 2008 (UTC)[reply]

It is both, the liberty was produced by many manufacturers under the eye of a co-ordinating organisation.So all engines were Liberty's and the different sizes and layouts were differentiated by the L- designator, thus Liberty L-4, Liberty L-8 etc. etc.Petebutt (talk) 06:48, 21 January 2012 (UTC)[reply]

Merger proposal

There is aproposalto merge this article with Lincoln Liberty engine, discussion is at Talk:Lincoln Liberty engine#Merger proposal Petebutt (talk) 06:43, 21 January 2012 (UTC)[reply]

So, as a result there is an entirely separate Lincoln chapter with most information repeating what is listed under History. And Lincoln isn't listed as a manufacturer with the top photo and list.Flight Risk (talk) 02:49, 17 October 2013 (UTC)[reply]

Production section issues

Lincoln Production has a different font than the rest of the headings.

I would suggest merging "Lincoln Production" content into general Production content.

The article states Durant was a Pacifist, however, Walter P Chrysler states in Chapter VII his biography "Life of an American Workman" the following: "I left Durant's office, caught a train to Washington, and went directly to the office of Col. Edward Deeds, who had been associated with Kettering in Delco and now was in charge of aircraft production for the War Department...Within three hours I had an order for 3000 Liberty motors."

"I found out that Ford was having trouble making the overhead camshaft cylinder heads. We were making them easily. So I went to the Ford plant and made a trade with Harold Wills...Lets trade cylinders for cylinder heads"

"Shortly after we began deliveries on that first order for 3000 twelve-cylinder Liberties we got another order for eight-cylinder airplane engines. By that time we were taking on all kinds of war work: trench helmets, hospital equipment, trucks, tanks and other things of metal."

"It had been my intention to discuss these war contracts with Billy Durant, on that hurried visit to New York, but I had gone ahead without consulting him. He never took me to task for that, however." --PerryTrenton (talk) 21:56, 7 August 2021 (UTC)[reply]

Unsubstantiated design claims

"After just five days, Vincent and Hall left the Willard with a completed design for the new engine, which had adopted, almost unchanged, the single overhead camshaft and rocker arm valvetrain design of the later Mercedes D.IIIa engines of 1917–18."

This article here and elsewhere stresses the similarities of the Liberty OHC valvetrain with that of the Mercedes D.III without reference or substantiation. 2600:8805:8000:3D:583C:9255:A34F:F1A2 (talk) 16:41, 20 December 2023 (UTC)[reply]

The archive of Scientific American contains many articles on the Liberty motor, including the debunking that the design was done in only five days. The Packard company had already worked 1 1/2 year on it. What happened in those 5 days was that the design was improved for better materials and easier production.
