bearings into the end pieces as the crankshaft bearings. 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 I will be Contrary to popular belief the Packard V12 4M-2500 marine petrol engine For more info, read about our auctions or email us with any questions. and a 6.50-inch stroke, which brought it to 2,490 cubic inches. DAA Industry Opt Out We need more information about your vehicle to confirm fit. It had a gearbox and a chain-drive set-up. ", Neal also notes that "the British did not specify tolerances and fits, and Packard had to take parts from an existing engine and make measurements to determine these specifications as best as they could, using engineering judgement where necessary.". The two engines face aft, through Joes Gear transmissions, each drive shaft connectinginto a Watson and Flagg V-drive which then drove the prop shafts back under each engine. 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)). 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. Packard had investigated the prospect of building Merlins under license as early as 1938. The boats were often built by the immortal Gar Wood. Theres an appealing counterintuitiveness to the notion that a (marginally) sloppier engine makes for a more effective fighter plane powerplant; its a bit like that chestnut about adding armor to the parts of the bombers with no bullet holes. What a beast of an engine! "Despite the commonplace assumption, the new-generation I'm told that some crews upgraded the engines in the field by changing the There are many variations on this basic storyline, more than a few of which are contradictory. During the early part of the 20th century, there were some Big Cars (now sprint cars) seen with Packard powerplants. Peso . 400 odd pieces at about $1 per piece to make one experimental motor I quickly The first engines developed 1,200hp, butlater modelswith higher boost levels by the end of World War II made1,500 hp. 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. the original engines were a boring Packard's assembly line was undeniably cutting-edge. Wartime conditions such as hull fouling and engine wear could sometimes cause the boats top speed to be degraded until maintenance could be performed. These beasts will propel the 50 ton boat at speeds up to 50 knots. If you win the auction, your card will be charged for the service fee and you pay the seller directly for the vehicle. But it can be made with the same ease, relatively cheaply, and on a similar assembly line.. The Packard V-12 PT Boat Engine. He turns the engine over by hand twice a month and it has so Missed updates will be sent once your connection has been reestablished. The Martelli Brothers, organizers of the BFGoodrich Tires Mint 400 in Las Vegas and the California 300, have acquired the historic Parker 400 off-road racing series. The main tube parts are 20mm electrical Number of bids and bid amounts may be slightly out of date. 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. Hydra-Matic: The First Successful Automatic Trans, The Asna Brand Still Seems Weird Decades Later. Introduced at the New York Auto Show in January of 1932, the classic Packard V12 was an all-new engine, but it did have a historical precedent with the company. Copyright 2023 BangShift LLC. The first engines developed 1,200hp, but You're the high bidder. "PT Boats were powered by three V-12 supercharged engines," remarks Roger Luksik, member of the Packard Motor Car Foundation's Board of Trustees. cast the engine housing once it's finished. On the other hand, I've also read that Packard's cutting-edge manufacturing methods made for Merlins with tighter, more consistent tolerances. 2. This will make a 12 cycle per revolution motor which The two engines face aft, through Joes Gear transmissions, each drive shaft connectinginto a Watson and Flagg V-drive which then drove the prop shafts back under each engine. The first engines developed 1,200hp, butlater modelswith higher boost levels by the end of World War II made1,500 hp. these photo's were sent to me by John and Michael of J and M. So if you are The Liberty engine showed strong again about a decade later, only in this case, on the White Triplex Special, there were three Libertys installed two side-by-side in the rear and one centered in front of them. the three engines. neodymium magnet based crankshaft, 6 sets of coil 'C' cores which fit in the Every part on our car engines has to be interchangeable with the same part on any other engine, and hence all parts have to be made with extreme accuracy, far closer than you use. And that meant taking the craftsman out of the equation to whatever extent possibleor in other words, embracing mass production. One of those cars was a 1919 Packard with a straight-six engine, while a 1923 model carried a V12 powerplant, probably a variant of the smaller V12s of the time period. producing a total of 4,500 brake horse power and could guzzle 5000 gallons of However I have another idea which I am also 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). A Holley 1685F aircraft carburetor supplied the fuel, fired by two spark plugs per cylinder. The U.S. Navy used the Packard V-12 Marine Engine (4M-2500) in all U.S. Navy World War II PT boats. by two spark plugs 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. Dump some 100 octant gas in it, let it get warm, and then give it hell! 60 degree Vee-type twelve-cylinder Liquid cooled 4 . The carb on a Packard PT boat engine is about the size of a small milk crate. 3 5M-2500 Packard-Marine V12 Engines. There were 1M, 2M, and 3M series marine engines so the 4M, -2500 was not a brand new engine but a new generation engine. However, the basic dimensions remained. This rules. 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. Required fields are marked *. 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. We are a 501c3 non profit that is in dire need of donations. 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. You get the idea! 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. ', "I replied loftily, 'I suppose that is because the drawing tolerances are too difficult for you, and you can't achieve the accuracy. The photo's below are of an early war Packard engine restored This particular Liberty was modified with four Zenith carburetors and custom-designed pistons. Instead, Vincent, Packards lead engineer, started with a clean sheet and designed a making them quite temperamental. These beasts will propel the 50 ton boat at speeds up to 50 knots. think it was a boat restoration project (great trolley). Lead times are no longer months upon months as they were in the middle of 2020 and throughout 2021, but the situation is still of some concern, and its forced engine builders to get creative at times. Each engine has 48 valves, 2 inlet/2 outlet per cylinder. Later: The secret of this low-cost, high-production manufacturing is the assembly line. plugs per cylinder, two distributors etc) S/No: 8614.

As WWII approached, both companies had extensive experience with aircraft engines under their respective belts. Ultimately, workers on both sides of the Atlantic were able to build an engine for the ages, flown to victory in all of the major theaters of combat. A Chief of Naval Operations (CNO) PT Boat Conference convened in May 1941 to discuss future PT characteristics. All U.S. PT boats were powered by three 12-cylinder gasoline-fueled engines. Tour the worlds only operating authentically restored WW2 Higgins PT Boat PT658 Engine room! If the part doesnt fit, it is machined until it does meet required specifications.

But there were also other six-and-eight cylinder engines that would find their way into race machines. With an aluminum block with steel cylinder sleeves and weighing in at 2,900 pounds, the engine had a 6.4:1 compression ratio, and a centrifugal supercharger; later models were also fitted with an intercooler. And a large part of that was Packard's ability to use modern industrial processes to create low-tolerance, highly interchangeable parts. Lot #37,084. should give it tremendous torque. But there is one designation that really had motorsports engine builders panting through the years. And at the center of its story are two great automotive marques, Rolls-Royce and Packard, which built Merlins by the tens of thousands simultaneously on both sides of the Atlantic. A Holley 1685FR downdraft carburetor, crank-driven centrifugal supercharger, and Delco-Remy 841 electric starter motor are retained. 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. powered by three Packard engines equipped with mufflers to mask their approach, capable of making 40 knots. Peso . by J and M Machine Co of Southborough, MA, USA, http://www.jandm-machine.com Your bid of $ is $ more that the current high bid of $.

However, the basic dimensions remained. These were serial numbers 43-43339 through 43-43338. This was sort of a race and the slower boat would get the lead boats rooster tail whipped over his bow and a resulting bath. Packard also needed to figure out how to obtain (or create) fasteners that used British thread standardssome of which had been further modified by Rolls-Royce to meet specific needs. Packard made a three terminal electrical device to synchronise A Rolls-Royce automobile engine may well have run better and smoother, and have been assembled with tighter tolerances, than a comparable Ford motor. It may have been a luxury automaker, but it was clearly operating at a scale that dwarfed Rolls-Royceand it achieved those production figures by embracing mechanized production. using for the crankshaft. Checking for missed updates. Focus and explanation of E PT Boat. The early 85 boats were equipped with W12s. than the "bumps" on the later mufflers.. 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.

Simple! Easily remove .010-.015 wear groves or polish poor-quality surfaces like new. 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. Under the Operators Manuals button you will find a PT Boat Engineers Handbook; essentially a Packard Manual without pictures. Both of these cannot be true. Or can they? Packards involvement in boat racing goes back to the early 1920s when the engine of choice was the Model 1237 V12 aero engine with the four numerals indicating its cubic inch displacement. at 2400rpm, some source state 1,800 hp.but that was the emergency rating at 2800rpm according to Packard documents. A chief engineer acting as an engine builder, something that certainly was a one-on-one situation. Packard Marine Engine 4M-2500 - Construction and Operation, Servicing Training Manual, September 1944, 427 Pages. Meanwhile Packard Electric would build wiring harnesses and create new types of wire to be used on aircraft and engines that would power both PT boats and bombers alike. This is perhaps where historians like Neal acquired the notion that Rolls-Royce did not supply tolerances for Merlin component production; small batches of parts and pieces could have, conceivably, been fettled to meet specified tolerances by skilled laborers on the bench before assembly, at least in the early days. These engines have dual ignition and if the two points were not in exact sync you ended up being the slow poat. had heavily modified the engines in P-563, P-564 and P-565 to achieve speeds of about 55 mph and added a muffling sytem for low speed stealth operations. . shows 6 of the 1/4" Dia x 1/4" long neodymium magnets from www.fieldforce.com We were all a bunch of 20 year old kids and pushing too hard in fairly rough water could bounce the boat out of the water hence the overspeed cutout. A little-known fact is that these engines were produced under license to Rolls-Royce. 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." View cart for details. Rolls-Royce vs. Packard: Who Built a Better Merlin? 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.

The Packard 4M 2500 engine powered most, if not all, of the US In this case we are talking about a tractor using a WWII Packard PT boat engine to drag the sled all the way home. 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. While Packard had a deal to make the Merlins for airplanes, the engines used in the boats had nothing to do with those. show the PVC / Styrene master so far. But when it was ready to try a run, it was Indy 500 driver Ray Keech at the wheel turning a scary 207.55 mph. The 4M variant produced 1,200 horsepower when new. Rolls-Royce manufactures a 'fitters' engine with parts being brought to the unit under construction on a bench. The tiny engine produced only 24 horsepower, yet pushed the 1,310 pound two-seater machine to almost 60 mph. Both built their global. My intention is to resin With a 6.375 bore and a 6.5 stoke, this gasoline-powered OHC V12 displaces 2,490 cubic inches (40.8 liters). However, there is substantial evidence that three boats in the OSS (forerunner to the C.I.A.) 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. 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. Were in that kind of situation.

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. 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. You may be able to find the same content in another format, or you may be able to find more information, at their web site. which were laser cut, the assembled crankshaft (I used brass wires through holes These engines are 4 stroke, water cooled, 60 degree, V- type with a 6-3/8" bore and 6-1/2" stroke, for a total of 2490 cubic inches of displacement. The WW I-vintage Packard V12 Liberty engine brought forth a significant increase in speed in 1919. The 4M-2500 is at best, a distant cousin. 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. "dashboard" tachometers show a top speed of 3000 rpm. Today, modern engine builders are building more Merlin horsepower with Allison V-1710 engines, connecting rods and replacement of the intercooler with an ADI injection system (half alcohol and half distilled water). 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. The saga of the Roll-Royce Merlin V12 supercharged aircraft engine is one of the most gripping engineering and manufacturing stories of the 20th century. The engineswere dry sump with an external oil tank which had special baffles to reduce foaming. It was a time when such events enjoyed huge attention and made the drivers celebrities. The motorsports implications stretched even further with the companys involvement with military production of fighter aircraft engines during World War II. This engine was used for both the 85 ft. crash boat, the more common PT-boats and The British Power Boat Co. high speed rescue launches . all the clockwork. Contrary to some sources, the Packard V12 4M-2500 marine engine did not start its life as a copy of the British Rolls Royce Merlin engine.

Melbourne using an Epilog Mini 50 watt CO2 desktop laser cutter, I want one of During the Second World War Packard built both marine and aircraft engines in its huge plant on East Grand Boulevard in Detroit. Rolls-Royce did even better at 82,117 (32,377 at Derby, 26,065 at Crewe and 23,675 at Glasgow), and Ford of Britain ultimately built 30,428 at its Manchester facility. (Note: These numbers vary slightly depending on the source.). choice with those. It had a long record of building aircraft engines that dated back to 1917 and included the . 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. However, using the older 4M-2500 engines, increases in the weight of the boats due to more weaponry offset the potential increase in top speed. The supercharger was toward the stern and the gear shifter toward the bow. That last factory began churning out engines in mid-1941, but not before Ford, like Packard, overcame a few hurdles. Rolls-Royce did not manage its incredible overall production numbersagain, greater than those achieved by Packard, albeit at multiple plantsby adhering to its prewar manufacturing methods: It did so by mechanizing. Lot #35,238. Union rules and demarcations had to be eased by dilution agreements, and such were the aptitudes of the British that all over the country the so called butchers, bakers and candlestick makers and their wives and girl friends increased the trickle of engines to a river of power.". First of all, there were three Packard-powered Indy Cars in the 1923 Indy 500. All Packard M2500 engines came with cranking motors and DC generators built by the Delco-Remy Division of General Motors in Anderson, IN. Makes for a pissed off skipper and we would be down working on very hot engines the minute we tied up. Bad ass. Did you mean to enter this number as a bid? Retained equipment includes a Holley downdraft carburetor, centrifugal supercharger, and a Delco-Remy electric starter. . directly, whereas the port and starboard wing engines faced foward and drove into 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 pictures below show earlier versions of the Packard V12 "Know Your PT Boat," July 1945, was created very near the end of WW II to use as an introduction to PT Boats for crews' in training. 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 . The 60,000 engines produced by Packard for the RAF and USAAF were of inestimable value.". Did Rolls-Royce simply forget to include this vital information when it handed Ford, and then Packard, stacks of documentation two years later? Whether youre scouring junkyards, ordering cores, investigating factory options, looking at aftermarket cast iron or aluminum blocks, or spending big bucks on billet LS blocks, youve probably noticed its been harder to find exactly what you want for the foundation of your LS build than it historically has.
