packard pt boat engine

And that meant taking the craftsman out of the equation to whatever extent possibleor in other words, embracing mass production. The 4M-2500 was the fourth marine variant, succeeding the 900 horsepower 1M-2500, 1,000 horsepower 2M-2500, and the 3M-2500, which debuted in 1939. 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. You are not connected to real-time updates. 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). Serial number P3255 is stamped in the crankcase base as pictured above. 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. Rolls-Royce Limited was established in 1904; the Packard Motor Car Co. was founded in Warren, Ohio, a few years earlier, in 1899, and set up shop in Detroit in 1903. shows 6 of the 1/4" Dia x 1/4" long neodymium magnets from www.fieldforce.com The supercharger was toward the stern and the gear shifter toward the bow. The idea is that the crankshaft will have 24 of these These engines were built by the Packard Motor Car Company, and were a modified design of the 3A-2500 V-12 liquid-cooled aircraft engine. 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 . Since boththe AAF85' Rescue Boat and the US Navy PT boat used the Packard 4M-2500 W8 to W14 engines, the handbook would apply to both. I am intending to use some The engine and ancillaries are finished in gray paint, which is peeling throughout. Please help! Data is a bit sparse on this category of Packard participation, but we know Packards competed on this track too. The supercharged 41-liter V12 produced 1,200 horsepower when new and features overhead camshafts and four valves per cylinder. 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. Robert was kind enough to send me these photo's which show The centre engine faced aft and drove the centre prop shaft The other thing was that when we were on patrol we idled all night so when we started back to base all engines were running as fast as they would go for maybe 2 hours. 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. However, at top speed, consumption increased to 166 gallons (628 l) per hour per engine (or 500 gallons per hour for all 3 engines). 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. Lot #35,238. He turns the engine over by hand twice a month and it has so That Packard name. If so please use the bidding box above. "dashboard" tachometers show a top speed of 3000 rpm. 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. electric motor (and possibly gearbox) housed in a cast shell and when completed it should fit the exact mounting conduit and a couple of fittings glued together.

Your email address will not be published. that I will be I have not looked at the layout of the PTs but the difference in the number of engines may be due to the need to allow space for the dispensary with eight litters in the stern of the crash boats, or due to the additional weight of the torpedoes. Packard marine engine, initially tagged the 4M-2500, was anything but a Packards early efforts resulted in the successful Liberty V12, which arrived several months after the United States April 1917 entry into World War I. Rolls-Royce began producing its Eagle V12 in early 1915, also to power warplanes; it started development of the PV-12, the engine that would become the Merlin, in the early 1930s and had running prototypes by 1933. 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. Its factories may not have looked exactly like the clean, ultra-modern Merlin production facility Packard constructed at its East Grand Boulevard plant, as period footage shows: But the storied marque, or at least the aircraft engine-building portion of it, evolved to meet the demands of wartime. Did Rolls-Royce simply forget to include this vital information when it handed Ford, and then Packard, stacks of documentation two years later? It was a legacy of its World War One job of building the famous Liberty engine. Number of bids and bid amounts may be slightly out of date. It should be noted that the method of determining the octane rating has changed since that time and the same gasoline , if tested today, would get a lower octane rating, probablyby 5 to 10 points. Much, but not all of the above information comes from http://www.PT-Boat.comand Packard documents on their website. 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. Your CA Privacy Rights (Shine the Light) 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. Required fields are marked *. 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." In this case we are talking about a tractor using a WWII Packard PT boat engine to drag the sled all the way home. This particular Liberty was modified with four Zenith carburetors and custom-designed pistons. . There were 1M, 2M, and 3M series marine engines so the 4M-2500 was not a brand new engine but a new generation engine. Your bid has been posted in the comment flow on the listing, and you can see other bids there as they happen. Dump some 100 octant gas in it, let it get warm, and then give it hell! 2010 March 1 update: Added camber information, and fuel tank capacity corrected. But in 1922, the governing American Powerboat Association (APBA) decided to lower the engine displacement to only 625 cubic inches, which was about half that of the 1237 cubes of the Packard 1237 engine. The Packard Marine is a powerful high-speed supercharged, lightweight engine of the aviation type. these photo's were sent to me by John and Michael of J and M.

PT Boats in Action Attack on Coastal Oil Installations Borneo WW2 Combat Footage w/ Sound. Since Autoweek is talking tolerance this week, it seemed like an opportune time to dig a little deeper into the Merlin storywhich, after all, is a big point of pride for Packard car owners like myself. Wartime conditions such as hull fouling and engine wear could sometimes cause the boats top speed to be degraded until maintenance could be performed. 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. It probably helped that America was not at war when ground was broken for itand anyway, the threat of Axis bombers flying to the Midwest to flatten it was somewhat less than the chances of the Luftwaffe raining fire on the manufacturing plants of the Midlands. Devil Boats Full Version PT Boat . [1] Five aero variants were produced, of which the 3A-2500 was the most numerous. And sometimes, the occasion calls for a Timex. Blueprinted, handmade and expertly tuned Merlins might have been nice to have under ideal circumstances, but WWII demanded materiel in almost unfathomable quantities. But it can be made with the same ease, relatively cheaply, and on a similar assembly line.. Enter Packard. The 4M-2500 is at best, a distant cousin. You get the idea!

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. I would like to have bought it, only it's in the US and I'm around the Their aircraft roots gave them many features of aircraft engines, such as superchargers, intercoolers, dual magnetos, two spark plugs per cylinder, and so on. Are you sure you want to proceed? The war was over, and the shortage of Packard engines for the PT boats never materialized. The first engines developed 1,200hp, butlater modelswith higher boost levels by the end of World War II made1,500 hp. this, the Packard V12 1M 2500 engine was used extensively by Garr Wood in his world Packard sold 98,000 units in 1940 alone.

I have fitted 10mm x 3mm x 3mm ball I am obviously not the first person to compare British and American-built Rolls-Royce Merlin engines; over the course of writing this survey, I found several other articles that covered similar territory and add further insight. 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. Each engine has 48 valves, 2 inlet/2 outlet per cylinder. A small history lesson told to me by Ken Nissen. If you don't win, your existing pre-authorization will be released. The initial Merlin engines may well have had a large number of hand-fitted components; the first generations, after all, were borderline-experimental. California Notice at Collection They were very respectable with finishes of 14th, 15th and 18th. The "pots" are The detail is amazing, I didn't expect them to come out so well, the rings Derek LudingtonLudington EnginesZumbrota, MN. We'll give you credit for the submission (of course) and what is cooler than showing all your gang that you have a story on Bang Shift? But there is one designation that really had motorsports engine builders panting through the years. The Packard Motor Co. is best known for its "super-luxury" cars. Rolls-Royce was crafting Swiss watches; Ford was cranking out Timexes. record holding speed boats of the 1930's and the licence built Merlins were not Remember These Woody Commuter Cars of the 1970s? . 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. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); We are always looking for good bang shifty stories, projects, photos & videos. engine, note the two bolted access panels on the side of each muffler rather Propulsion. See each listing for international shipping options and costs. 14. We make motor cars far more accurately than this. the three engines. The license built Merlin engines were not produced by Packard until well into the war years and were of smaller displacement (1670 CID). 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. Packard V12 Marine Engine that looks like the original V12 engine but is actually an Microfilm Reel provided by Al Ross File: 08Packard_4M-2500-Training Manual.pdf: The main tube parts are 20mm electrical Thanks Jerry 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.". Or can they? And even in those early years, Packard realized the importance of on-the-water motorsports and really supported it. 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. The supercharged 41-liter V12 produced 1,200 horsepower when new and features overhead camshafts and four valves per cylinder. "Despite the commonplace assumption, the new-generation This engine WAS for sale, (now sold) it was built on Oct 19, 1943 and 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. 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. 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. Melbourne using an Epilog Mini 50 watt CO2 desktop laser cutter, I want one of 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. 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.

Terms of Use, Your Privacy Choices The first engines developed 1,200hp, but 1939). 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. should give it tremendous torque. 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. I have seen daylight under the hull of our companion boat many times. The tiny engine produced only 24 horsepower, yet pushed the 1,310 pound two-seater machine to almost 60 mph. From this modern vantage point, it might seem inevitable that Rolls-Royce would join forces with Packard to produce Merlins. by two spark plugs per cylinder. It conjures up thoughts of the rich, the famous, long limos along with the brands perfectly molded fenders and hoods. This content is imported from YouTube. Spring Carlisle Collector Car Flea Market & Corral, Camp Plymouth Spring Military Vehicle Show & Swap Meet. The Eight was available on several wheelbases, from 127.5 inches to 145.5 inches.

It had quickly become evident that the project was going to be more complicated and expensive than planned and Packard lost $300,000.00 (1939 dollars) on the 3M-2500 project. all the clockwork. That is the only way we can achieve mass production.'". Packard modified them for marine use in PTs, hence the "M" designation instead of "A". those! original engine. 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. Also, the manifold pressures on these Packard engines have been increased dramatically enabling the vintage engines to acquire some 3,800 horsepower. A Rolls-Royce automobile engine may well have run better and smoother, and have been assembled with tighter tolerances, than a comparable Ford motor. In the legend of the Merlin, any theorized variation in fit and tolerances cannot be more than a very tiny footnote. It was offered in four models, the Standard Eight, Custom Eight, Deluxe Eight, and the Speedster. I use painters tape, which comes off easily and doesnt leave any glue residue. finished crankshaft with magnets installed. P.T. If you win the auction, your card will be charged for the service fee and you pay the seller directly for the vehicle.

A looking for someone to restore your PT boat engines, these guy's have the During the early part of the 20th century, there were some Big Cars (now sprint cars) seen with Packard powerplants. 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. Others, however, like the two-piece block, were actually designed by Rolls-Royce and not yet implemented in production. The first "production" version of the engine was the Merlin I, which arrived in 1936, but fewer than 200 examples were built. However, there is substantial evidence that three boats in the OSS (forerunner to the C.I.A.) 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. 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. $12.95 + $5.95 shipping. [1] Five aero variants were produced, of which the 3A-2500 was the most numerous. 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.
