Peso . This Packard 4M-2500 engine is one of approximately 12,700 built and is believed to have powered a US Navy patrol torpedo (PT) boat during World War II. By mid-June 1940, Packard had taken possession of the plans and parts initially given to Ford, and began an ambitious programled by Packard engineering boss Col. Jesse Vincentto tool Detroit up for Merlin production. As Harvey-Bailey writes in The Merlin in Perspective: "Prior to the War the majority of operations in aero manufacture, build and test had been skilled in both a Trade Union and actual sense. They were subsequently upgraded in stages to 1500-hp (1,150 kW) each, for a designed speed of 41 knots (76 km/h (47 mph)). It was a time when such events enjoyed huge attention and made the drivers celebrities. Missed updates will be sent once your connection has been reestablished. New to Buying Tools? 60 degree Vee-type twelve-cylinder Liquid cooled 4 . America is like one of those old-fashioned six-cylinder truck engines that can be missing two sparkplugs and have a broken flywheel and have a crankshaft thats 5000 millimeters off fitting properly, and two bad ball-bearings, and still runs. We (engineers) never objected because this blew the carbon out of the engines. From this modern vantage point, it might seem inevitable that Rolls-Royce would join forces with Packard to produce Merlins. Your CA Privacy Rights (Shine the Light) I use a harmonic balancer installation tool for big and small block Chevys and just flip it around to mount on my lathe. Atlantic Cruising Club's Guide to Florida's West Coast Marinas - Book with b Leave feedback about your eBay search experience - opens in new window or tab. But it's even tougher to prove conclusively, especially (as Neal notes, regretfully, in Master Motor Builders) given that so many Packard records were destroyed when the company folded. The engine continued to bea four-stroke, 60-degree V-12 with a6.40-inch boreand a 6.50-inch stroke, which brought it to 2,490 cubic inches,with four valves per cylinder.

Packard V12 Marine Engine that looks like the original V12 engine but is actually an Most recently, I was told very matter-of-factly (and by a Brit, if that makes any difference) that Rolls built a more precisely fitted, finely tuned engine that had slightly higher performance potential for a given unit. I Hunt The Frontmulti-car dirt late model team and one of the most successful content creation organizationshas announced a new regional tour called the Hunt the Front Super Dirt Series presented by Sweet Victory Apparel. I can only imagine Rolls-Royce owners look back on this period of history with equal admiration. did not start it's life as a Copyright 2023 BangShift LLC. Navy's 768 PT boats, two astern and one amidships for better service access. After the challenges were overcome, they had redesigned the engine patterns,upgraded the quality control and metallurgy standards and made many major changes that involved extensive redesign. The mistake here, and the foundation of the file-to-fit Rolls-Royce Merlin idea, is likely in conflating early engines, which were built in relatively limited quantities throughout the early to mid-1930s, with the mighty (and mightily improved) mass-produced Merlins that emerged as the war progressed. 1939). But its section on Merlin development, the superchargers of which Hooker played a role in developing, is illuminating: "In my enthusiasm, I considered that Rolls-Royce designs were the ne plus ultra, until the Ford Motor Co. in Britain was invited to manufacture the Merlin in the early days of the War. The combined power of the three 27 liter Liberty engines was quoted as 1,500 horsepower from its 36 total cylinders. This much power could push the fully loaded boats at 45 to 50 knots. Remember, Packard, and for that matter, Ford of Britain, were able to jump more or less into mass production of the Merlin, while Rolls-Royce took the engine from a blank sheet of paper to eventual mass production at its three facilities. The Packard 1A-2500 is an American V-12 liquid-cooled aircraft engine designed by Packard in 1924 as a successor to the World War I-era Liberty L-12. Bid for the chance to own a 1920s Packard V12 Marine Engine at auction with Bring a Trailer, the home of the best vintage and classic cars online. licence built US made copy of the British Rolls Royce Merlin engine, this has The BaT Service Fee is 5% of the bid, with a minimum of $250 up to a maximum of $5,000. Still another Big Car was pictured with the lettering Packard S8, probably indicating a straight-eight engine under the hood. This may have been in part caused by how they were drained for storage between the wars. We make motor cars far more accurately than this. Harvey-Bailey's assessment seems to reflect the consensus: "At Squadron level there were times when there were fortuitous variations in reliability either way but when dealing with large numbers of engines at Group or Command level there was good consistency in results between British and Packard engines. Packard built between 12,000 and 14,000 marine engines during the war,depending on the source, three of which went into each of the Navy's 768 PT boats, two astern and one amidships for better service access and the British Vosper MTB's (Motor Torpedo Boats) in addition to the USAAF 85' Air Sea Rescue Boats which used two per boat. . This notion is also reflected in the March 1946 issue of Flying magazine, which includes a retrospective on the powerplant by Paul H. Becker titled Mass Producing the Merlin: It took the war to prove that the aircraft engine is not that complicated micro-micro-inch construction problem peacetime talk has made. But that's only because the company employed tradesmen who could fit the parts. original engine. An American assembly line reverses this procedure. Note These modifications have been mentioned by several sources but specifics remain elusive. In Derby, after almost a quarter of a century of the business growing up with the workforce, the true skills had become ingrained and many vital bits of knowledge were almost part of the atmosphere in which people work and often not formally documented. Your bid of $ is $ more that the current high bid of $. . However, the basic dimensions remained. The 4M variant produced 1,200 horsepower when new. these photo's were sent to me by John and Michael of J and M. So if you are Owing to variations in development programs, the varied aircraft they powered and the different mission profiles they fulfilled, it is difficult to compare Packard and British-built Merlins directly to determine if one was in fact "better." And even in those early years, Packard realized the importance of on-the-water motorsports and really supported it. The boats were often built by the immortal Gar Wood. LS swaps are popular for many reasons, but there are a lot of variations and details to sort through more of them than you may expect and many of them are associated with the intake manifold. Data is a bit sparse on this category of Packard participation, but we know Packards competed on this track too. Fighter engines were very popular, particularly the Packard V-1650 Merlin engines, many of which were modified for air racing events such as the Thompson Trophy, Bendix Trophy and Cleveland Air Races. Auctions Search Auctions Live Now Premium The 4M-2500s initially generated 1200 hp (895 kW) each, together roughly the same power as a Boeing B-17 bomber. producing a total of 4,500 brake horse power and could guzzle 5000 gallons of Spring Carlisle Collector Car Flea Market & Corral, Camp Plymouth Spring Military Vehicle Show & Swap Meet. (Opt Out of Sale/Targeted Ads). A Rolls-Royce automobile engine may well have run better and smoother, and have been assembled with tighter tolerances, than a comparable Ford motor. making them quite temperamental. Both of these cannot be true. gear ratio's on the supercharger impeller, increasing the engines horsepower but the likes of General Electric on superchargers went into the development of the But much like Abraham Walds WWII-era work on aircraft survivability, its tough to say exactly how much of this neatly packaged story is nothing more than enticing elaboration spun around just a few spindles of fact. The supercharged 41-liter V12 produced 1,200 horsepower when new and features overhead camshafts and four valves per cylinder. There have been many motorsports events in which Packard engines participated, and a high percentage of the time, participated at a high level. But were they better than the ones built in Britain? We can have substantial parts of the population committing suicide, and still run and look fairly good.Thomas McGuane (b. Both built their global reputations as top-level luxury automakers on the strengths of their engineering expertise and high production standards. In any case, Packard's version of the Merlin XX, which the Detroit automaker dubbed the V-1650-1, was ready to run by August 1941. If you want to dive into the minutiae of Merlin development, it's worth grabbing a copy of The Merlin in PerspectiveThe Combat Years, by Alec Harvey-Bailey; there's simply too much info to relate it all here. 1943 Studebaker US Army Flying Fortress Cyclone Engines WWII . In twin-screw installations the ideal arrangement is to have the tops of the propeller blades turning outward for better maneuvering qualities but this was not available with the Packard engines in the 85s which made docking a bit more challenging as it was almost impossible to get the stern to move to starboard. That last factory began churning out engines in mid-1941, but not before Ford, like Packard, overcame a few hurdles. Much, but not all of the above information comes from http://www.PT-Boat.comand Packard documents on their website. Propulsion. As Robert J. Neal writes in Master Motor Builders, a tome documenting Packard's non-automotive engines: "This was but the beginning of a monumental task of redesigning an engine which was not originally designed for mass production so that it could indeed be made by American mass-production methods, and so that it could be fitted with American fittings and accessories as mentioned above [for example, carburetors, fuel pumps, generators and so on] or British accessories and fittings, depending upon which government the engine was intended for. This will make a 12 cycle per revolution motor which Like so many historical yarns, the idea that American know-how was able to build a better Merlin (either through greater precision or some degree of calculated, mass-producible impression, depending on whom you ask) than Rolls-Royce is hard to dispel out of hand. The right hand picture There are few things better than pulling tractors that use monster vintage engines to put the power to the ground and haul the sled. It is larger, lighter-per-horsepower and has more parts than the automobile engine. But there is one designation that really had motorsports engine builders panting through the years. I am intending to use some The 3A-2500 was an improved version of the 2A engine used on the Huff-Daland XB-1 Liberty bomber of World War I vintage. This involved everything from the time-consuming task of redrawing plans for the engines from British third-angle projection to the first-angle projection used in American manufacturing to creating the tooling and jigs needed to assemble them. This is a 1,500hp (stock) Packard 4M-2500 which was largely based off of the Liberty airplane engine that had been modified for racing . A number of Ford engineers arrived in Derby, and spent some months examining and familiarizing themselves with the drawings and manufacturing methods. Autoweek participates in various affiliate marketing programs, which means we may get paid commissions on editorially chosen products purchased through our links to retailer sites. To keep things simple there was a clutch or gearbox with just a fixed rearend ratio. But it can be made with the same ease, relatively cheaply, and on a similar assembly line.. Basic characteristics. the original engines were a boring Only 15 examples of the 1M, 2M, and 3M versions were built, but 4M production ramped up ahead of the United States entry into World War II, resulting in 12,700 examples being manufactured between 1940 and 1945. This rules. A chief engineer acting as an engine builder, something that certainly was a one-on-one situation. Three marine versions, used most prominently in American World War II PT-boats, the 3M-2500, 4M-2500, and 5M-2500, were also derived from it. For more info, read about our auctions or email us with any questions. Taking some of those ideas and the basic platform as inspiration, Packard built upon it. If you win the auction, your card will be charged for the service fee and you pay the seller directly for the vehicle. However, at top speed, consumption increased to 166 gallons (628 l) per hour per engine (or 500 gallons per hour for all 3 engines). The Packard Motor Co. is best known for its "super-luxury" cars. British Merlins were eventually built at a quartet of facilities: Rolls-Royce Derby, plus two Rolls-Royce "shadow factories" at Crewe (currently Bentley's works) and Glasgow (twice the size of Crewe, its foundry provided castings for the other operations), and a Ford factory in Manchester. While PT-boats had an option to muffle their engines by routing the exhaust underwater, no such option was on either the 63' or 85' rescue boats, so with straight pipes,stealth operations were not an option on most rescue boats. Good luck! It had a gearbox and a chain-drive set-up. The supercharger was toward the stern and the gear shifter toward the bow. If you have something to share let us know. Though these initial discussions went nowhere, the British declaration of war on Germany in September 1939 meant that a new manufacturing partner was urgently needed. And sometimes, the occasion calls for a Timex. A Rolls-Royce was crafting Swiss watches; Ford was cranking out Timexes. which were laser cut, the assembled crankshaft (I used brass wires through holes This is the aircraft version, the marine version was the 3M-2500. Please help! This restored motor was apparently going into a The motorsports implications stretched even further with the companys involvement with military production of fighter aircraft engines during World War II. All Packard M2500 engines came with cranking motors and DC generators built by the Delco-Remy Division of General Motors in Anderson, IN. WINNERS UPDATE Question of the Week: What's the One Car From Your Childhood You Wish You Could Own Today? And that meant taking the craftsman out of the equation to whatever extent possibleor in other words, embracing mass production. Engineering refinements meant that by the end of the war, the Merlin 66, an intercooled variant of the engine sporting a two-stage, two-speed supercharger, was making 2,050 hp (increased from 1,030 hp in the Merlin II)and these improved engines were allowing aircraft to operate at significantly higher altitudes, as well. improved versions with higher boost levels nominally made 1,500hp. Also, the manifold pressures on these Packard engines have been increased dramatically enabling the vintage engines to acquire some 3,800 horsepower. For some perspective here, note that total Rolls-Royce automobile production from 1936-1939 totaled 6,244 (and that includes 3,824 units of 20/25 production, which spanned 1929-1937; thanks to Mark Lizewskie of the Rolls-Royce Foundation for the information). But never fear, Carl Vincent, a chief engineer for Packard, came up with a most innovative solution to the problem when he removed the six cylinders in the right bank of the engine-Merlin and capped them off. the three engines. My intention is to resin Retained equipment includes a Holley downdraft carburetor, centrifugal supercharger, and a Delco-Remy electric starter. The Eight was available on several wheelbases, from 127.5 inches to 145.5 inches. While Packard was also commissioned to produce the excellent Merlin aircraft engines that powered the famous Supermarine Spitfire fighters of Britain, these were never actually used in ELCO PT boats - instead reserved for the overseas British aircraft demand. Our car experts choose every product we feature. (1.6mm) marine ply as part of a test of a few of the new laser cut ribs for boat What a beast of an engine! Packard, you see, was a lot more than just Knudsen's Plan B after Ford rejected the Merlin contract. The idea is that the crankshaft will have 24 of these In early 1941 the U.S. Navy Bureau of Ships (BuShips) lent Packard engines to both Huckins and Higgins, which wanted to build competitive boats at their own expense. [citation needed], Data from Aircraft Engine Historical Society[5] and Race With the Wind By Birch Matthews[citation needed]. And to give a sense of how thoroughly this largely parallel, if somewhat staggered, transatlantic development effort has clouded the record, Neal states that Packard modified the design two-piece block to better facilitate production; when Rolls-Royce eventually implemented a slightly different two-part block, Packard subsequently adopted the Rolls-Royce design. The consumption rate for each engine at a cruising speed of 23 knots was about 66 gallons (250 l) per hour (200 gallons per hour for all 3 engines). Detroit's mass-production know-how yielded over 55,000 Merlin V12 aircraft engines during WWII. Both propellers turned the same way, clockwise (right-handed), looking from aft. They were very respectable with finishes of 14th, 15th and 18th. The three successive versions of these engines were designated as 3M-2500, 4M-2500, and 5M-2500, each of which had slight improvements over the previous version. FrozenMerc, Nov 11, 2011.

Attempting to connect. See it in all its glory here: All of this seems to back up the claim that Packard went its own way when building the Merlin, at least when it came to tolerances. bed of the The 4M-2500 is at best, a distant cousin. [1] Five aero variants were produced, of which the 3A-2500 was the most numerous. 100 octane aviation fuel in one night of operations. And a large part of that was Packard's ability to use modern industrial processes to create low-tolerance, highly interchangeable parts. What many are unclear on is exactly what they were, and where they came from. Following the attack on Pearl Harbor in December 1941, and the United States' declaration of war on the Axis powers, civilian automobile production quickly ceased; by early 1942, Packard was free to focus all of its effort on military engine production. Senior Packard management report that Jesse Vincent, Packards lead engineer, started on the 3M-2500 experimental engine in 1939 based on converting the Packard 2500 aircraft engine into a marine versionand seven were built for the U.S. Navy. Another photo showed a 1916 Packard Twin-Speed 299 car with a V12 engine, possibly a Liberty engine. by two spark plugs per cylinder. 2. and then by the end of the war 1500 BHP, therefore a late war Elco 80' PT had three engines All contents 2023 The best vintage and classic cars for sale online | Bring a Trailer, Privacy Notice Packard Marine Engine Piston MA-67958 NOS Brand New $34.99 Seller: packards1 (9,962) 100% Buy It Now +$8.00 shipping Sponsored Packard Marine Engine Pump Shaft MA-69846 NOS Brand New $64.99 Seller: packards1 (9,962) 100% Buy It Now +$8.00 shipping Sponsored Packard Marine Engine Distributor Gear MA-67704 NOS Brand New $25.00 A normal patrol for these boats would last a maximum of 12 hours. In this case we are talking about a tractor using a WWII Packard PT boat engine to drag the sled all the way home. Are you sure you want to proceed? Packard built the Rolls-Royce Merlin aero engine under license alongside the 4M-2500, but with the exception of the PT-9 prototype boat brought from England for Elco to examine and copy, the Merlin was never used in PTs. looking for someone to restore your PT boat engines, these guy's have the document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Please enable JavaScript to engage in the discussion on this site. changed my mind, I am getting the crankshaft parts cut though as I have no Rolls-Royce vs. Packard: Who Built a Better Merlin? 3/8" (9.5mm) styrene tube from the hobby shop. built PT Boats.
