Harley-Davidson Servi-Car

Though sales dropped during the years of the depression in the Harley-Davidson survived. A strong network, police and military conservative business management and exports were all a part of survival.

Their servi-cars had upgraded continuously during the gaining two rear brakes in an enclosed chain in ’38, and a tow-bar, which was given a attachment in ’39, (eliminating the to remove it and carry it separately in the trunk). Their servi-car was widely by small businesses, the department, the military, used car and repair shops, despite motorcycle enthusiasts feelings the servi-car had no real practical and was something to be driven and not ridden.

The servi-car got larger and the rear suspension was modified to body roll, cast brake drums replaced the steel housing, and the transmission was and the axle housing was improved for , as well as the clutch and gearbox. The got tubular front fork in place of the old forged I beams.

WL 750cc 1940 WLD 45ci

Development of a military motorcycle had underway in Milwaukee for more a year, with prototypes of the 61ci OHV, and the 45. Just the German invasion of Poland, in of 1939, two forty-fives with the designation WLA were shipped to Knox, Kentucky for testing. The weren’t as nimble or light as the racers built by their but it was a durable and reliable motorcycle.

By the 1940s the only ones in the United States were and their competitor, Indian. than their production of to meet military needs in War 11, the Daytona 200 was also won again year, with a WLDR


1941 Knucklehead GA Servi-Car

Harley-Davidson answered the to war again as World War 11 started. of civilian motorcycles was almost suspended for production of military The service school was converted to the Quartermasters School for the training of mechanics, and the entire motorcycle supplied American and Allied during World War 11, during time they shipped than 90,000 motorcycles and the coveted Army-Navy E for excellence in production.

Their servi-car was popular with commercial as delivery trucks. A new frame was in 1941, with a stronger in a welded rather than tube, with front that fitted the 74ci, and the ratio was increased to 4.75:1. The grew in popularity with users, with it’s to increase business, cut costs, and profits.

The box could be used for as well as a carriage utility. The flathead proved to be the most and reliable motor in their It was the economical equivalent to trucks for delivery service, and to pick up and parts for many small

Even though the war going on Harley-Davidson didn’t ignore the of the public, and the their racing for bigger and better. They a 74ci OHV V-Twin for 1941, they designated the FL. The FL premiered a rated 48 horsepower at 5,000 with a top speed of 95 miles per

The Knucklehead’s high speed was motorcycle among the police as well as other motorcycle With the cal for more power, the seventy-fours, which were this year got new larger, increased in diameter, heavier an the rocker arms were to improve top end lubrication.

The new crankcases for the 61ci and the 74ci ohv have the baffles the previous had to equalize the lubrication to the cylinders, some of the problems with crankcase pressure, which to produce more horsepower. The Eye design stayed as the speedometer design, with a chrome serving as part of the tank and design on both sides of the tank.

Larger intake a redesigned manifold and a new carburetor helped to increase it’s The OHV Knucklehead remained in production and was continued in spite of the demand for for the military, and stayed in production 1948, proving the basis for the Shovelhead, and even the newer engines to come in later

1941 EL 1941 FL

These 1200cc OHV twins designated as the F and FL the FL being higher compression. designation was added in following to represent different styles, types, and other features were added. The colors were still available Clipper Blue, Cruiser Black, Light Red, and Green. Tire sizes to 5.00 x 16 inch adding to a comfortable ride, and a new Vane-type oil helped to ensure the overall of the engine.

Cruiser Green Squadron Gray for color but with the need of production of motorcycles to be built in support of the war color options became and less available. The first of the rocket-fin muffler was featured year, and the deluxe model with a chrome package consisted of chrome rims and instrument panel.

Along a change to a 1/2 inch longer manifold, the heavier flywheel of the OHV was now shared with the 61ci E as well as the clutch upgrades were applied to the 74s. 2,500 of the new 74ci FL’s built. The rocket-fin muffler replaced the fish tail were much quieter. The muffler got the nick name of the (muffler).

The tail — housings were now painted rather than the bodywork

Reduction of orders for military came, sp the company started to civilian production. Most of the motorcycles built for the war effort WL 45s.

1941 WLD 45ci WLDR 45ci

The military brought improvements to the forty-fives continued as the workhorse for the military. The were also applied to the forty-five models. The aluminum-head got a larger crankpin, became sportier, hot beefed up cams, valve springs, and a bigger producing around 35 horsepower, the iron-head WL became the economy with a reduced compression of 4.74:1.

A factory racing appeared this year, as as the WR, (flat track), and the WRTT racing-scrambler model, which had flat valve lifters of rollers for higher rpms. The was rated at 7 more horsepower the WLD, and the forty-fives got stronger transmission, and rear brake year. Because of the war production Class C racing was set back as of a non-priority in production and the WLDR was discontinued during the summer, as the entered the war.

1941 UL 1941 ULH 80ci

Because of the no changes were made to the from 1941 to 1946, and the were basically produced the improvements from 1940, and years. The aluminum heads optional on the 74ci UL, and standard on the ULH. 16 inch wheels now standard, with 18 inch becoming optional, with an of chromes rims, at $2.50. handlebars remained optional, as in years, with the Buckhorn remaining standard.

The tail-light assembly housing was to black instead of the same as the rest of the motorcycles color and a longer rocket-fin silencer the previous fishtail muffler. The was a quieter muffler without the wool packing which burned out.

1941 was the year for the 80ci flathead.

1942 WLA 45ci Army

The ordered 745 WLA’s in March of , and by 1941, most of Harley-Davidson’s was devoted to the military. The WLA, for the vast majority of Harley-Davidson’s production. Engaged on priority war Harley had the authority to produce all the rubber, and steel it needed to motorcycles.

Yet there was still shortages, and the Army requested all unnecessary rubber be left off the as there was a rubber shortage. So footrests and kick-starter pedals left without the rubber. was also left off, complied with the military’s for less weight. The rear were blacked out on many of the motorcycles, during the war, to being seen by the opposing

The British were making do 350/500cc singles, and the British tried to get William Harley to the smaller 30ci twin, (of the British were quit about), but, Bill and the Army was later convinced the 45ci was just what needed. It’s fuel was 35-37mpg, (13ltr/km), and being a engine, it was nicely under-stressed.

The were supplied on cost to the during the war effort, on a cost-plus 10 per basis, so there was very profit margin. Still, stayed in business, and additional were made for spares to the demand for their motorcycles for the effort.

1942 WL 1942 WLC

were two variations on the WL theme. WLC was for the forces (as Canada had been in the war 1939) and, although similar to the WLA, it differed in ways. It used the big twin’s and front brake, transposed the and front brake levers and had a gear change. It didn’t the WLA’s rear luggage (designed for a 40lb/18kg radio) but with a toolbox on the front

The WLC formed a substantial part of wartime effort, as twenty of them were built. The type luggage rack, was by a heavier duty square to carry a radio and a fork front scabbard to carry.

Eighteen wheels and big D-section mudguards prevent mud clogging off-road, and was a substantial skid-plate to protect the and gearbox.

A big oil-bath air cleaner was added, with a heavy duty rack, ammo boxes and scabbard.

Harley Davidson more than 88,000 of motorcycles during World War 11, supplied enough spare to assemble still another Reports of the 45-inch WLA surviving crashes, parachute drops, fire, desert heat, and snows with primitive, if any is legend. The WlA became a useful for scout duty, dispatch communications, and traffic control, police duties, as well as a force for armored divisions.

The still wanted a shaft-drive twin as its standardized military so they produced a motorcycle, horizontally opposed cylinders, had a drive shaft, designed for use, designated the XA. The XA was a 750cc flat twin. The Army loved it.

It featured a foot-shift 4 transmission, was shaft driven, had a clutch, a lengthened WLA fork, a clearance flat fender, to keep mud from building up the front wheels, and a plunger suspension. The XA 750, ran cooler the WLA and had what they considered a messy chain drive and further between overhauls. it used additional aluminum.

XA 750 — Horizontally Opposed

The Army ordered 1.000 of for military use at around $870 The WLA and XA were both produced for the but the XA was discontinued, as it was decided that the WLA do the same job at a considerable less and the WLA was 45ci flathead with a top of 65 mph. The Army Jeep, along shortly after, took over the role of the The WLA and XA were both produced for the Only 1,011 XA’s built.

One of the advantages of the opposed engine was having the cylinders in the air-stream for cooler running The XA had a compression ratio of 5.7:1, 23 horsepower at 4,600 rpm, a x 3.125 inch bore and 23 horsepower at 4,600 rpm, a primary drive, 4 speed 6 volt battery, 58.75in weighted 538lbs, with a capacity of 4.1 gallons. It’s top was 65 mph, and had an oil capacity of 2 quarts, and 4 x 18 tires.

The XA, was the only shaft-driven that Harley-Davidson had produced.

Davidson, company president at the age of sixty-five in 1942, leaving William Harley and Arthur left of the original four fathers of the Harley-Davidson Company

The civilian service training was changed to the Quartermaster School for military mechanics, maintenance, and of the WLA forty-five as a priority in 1942.

1943 WLA — 45ci — Army

In 1943, received the first of it’s Army-Navy E Awards for excellence in production. Many American got their first exposure to motorcycles overseas, and many of the found their riding to be one of their more pleasant memories, and went on to buy a big twin for in their civilian lives.

For afterwards, all over the world, new WLA’s, their engines, and and pieces, went on sale at bottom prices as their any compensation for the massive overstocks behind after the war ended. helped to bring thousands Harley-Davidson ownership, and also Harley-Davidson’s influence in Europe. The 1340cc twins were the of the highway until the overhead 74 cubic inch superseded with the 1200cc FL series.

The 45ci, 750cc became the running flathead in Harley history.

1943 Army-Navy E William Harley

In September of Bill Harley, suffered a heart …, leaving Davidson as the last of the original founders. Arthur lived to see the end of the World War.


WL 1944 WLD

The WL series remained in after the war and saw years of service it’s use in their servi-car. The WR engine got more compression, cams, and a roller bearing Production based on racing quite popular in the US during the forties.

With almost the Harley-Davidson production being to production for military use, to 90,000 WLA army-version motorcycles had built and shipped from to 1945.

1945 WLD

With War 11 ending, conversion back to of civilian motorcycles resumed in of 1945. With the conversion to production and reductions in government for military bikes, and the post-war for motorcycles being high, the was back to the Big Twins. Surplus war were sold in large at increased discounts. There was a in production in 1945 of the FL series as well as other civilian

Less than 1000 FL were produced. Wartime shortages were still seen as well as few color for the civilian motorcycles. Gray and Red basically the only color available, until Black and Sky were offered again in for their first year of scale civilian production. Les 2000 OHV models were during the war, with main production being for the military, though testing and continued.

Work on the first telescopic front fork was which a prototype was fitted to a in 1945.


1946 WL — 750cc Flathead

The showing of hydraulic dampening for the wheels was seen on the Big-Twins in with the application of a Monroe absorber joined at the front springs which replaced a friction device. The Knucklehead was on way to history by 1946 and 1946 was the year for full scale production since the war ended.

was also the last year for the Eye instrument panel. The speedometer was two-tone instead of silver the numbers matching the color of the circle in a design known as the style speedometer. The three combinations that were this year were gray/white, and black/silver, for face-covers. was still a post wartime shortage, and Black and Skyway didn’t became available as color options until the progressed.

This would be the last year of the streamlined Stainless steel trim, tank badges, chromed levers, gates, gas caps, and lamps were added later in the year as production of models got underway again and the model nameplates were

With the testing and development of the OHV’s, realized that riders be wanting oil-tighter, and smoother motorcycles that were reliable, transmissions that more conveniently, with starting. The shifting of gears was done by a shift lever required the rider to take his off the handlebars to shift the gears. were all projects for improvement of the up-coming models.

There were more options with the post-war though some of the seat were still limited. A mirror was added with the solo group, along a trip odometer, safety-guards, and a set cover. The hinged rear making tire changing stayed as part of their for several more years.

OHV Knuckleheads

The post war peacetime brought the racing market in focus. The company introduced a flathead WR model which to be one of the best racing motorcycles Attention was given to getting horsepower from the WR and getting suspension, more effective and foot-shifting to the racing circuit.

The 200, as the traditional season’s didn’t resume until the year.


1947 FL WLD

Several Revisions came the resuming of full civilian in 1947. The fuel tank was to fit a new instrument panel, the new speedometer now had a two-toned black and white with italicized numbers a red pointer needle. The fuel was redesigned to fit a new instrument panel, and oil and generator lights were together in a small rectangular with single lens, in the center of the tank.

Four options were offered in Flight Red, Cruiser Skyway Blue, and Brilliant

In 1947 a new plant was purchased on Drive in Milwaukee which was the A. O. Smith Propeller Plant, during the war, shipping of new to Juneau Avenue for final and full civilian production with updates of the ’41 Chrome and other accessories added again for the civilian a zippered black leather jacket was added to their catalog, becoming the first black leather motorcycle and the Deluxe Buddy Seat, was discontinued during the war returned for use.

Close to 1200 were made for 1947, for twelve-year run winning a loyal from motorcycle riders and an icon for The Harley-Davidson Motorcycle The racing circuit was still a of Harley Davidson’s interest in Harley-Davidson racers captured the TT, National Miniature TT and Nationals at Springfield and Milwaukee, and dirt racer, Jimmy Chann, the first of Three consecutive AMA National Championships this


The Panhead

In 1948, started the year of with brand new motorcycles, and several new Overhead valves, aluminum hydraulic lifters, better and newer improved lubrication the new features to both the 61ci and twins this year. The model OHV twin’s, became as the Panhead because of the pan-like rocker covers.

The 1948 FL came with a 45 degree cubic inch displacement, x 4 inch bore and …, and a 7:1 ratio with 50 horsepower at rpm’s, a 4-speed transmission, and rear drum brakes, ignition, chain primary and drive, hydraulic valve a new oil pump, a strengthened steel down-tube frame. The frame was to accommodate the new taller engine became known as the wishbone because of it’s bowed down-tubes.

The new frame came a mounting plate for crash-bars, and a lock. The new engine for this carried it’s oil inside and was The Panhead’s new hydraulic lifters, some of the previous models the of cooler running and maintaining exact valve adjustment.

The Panhead’s new oil pump did a better and thorough job of getting oil to the needed of the engine. The Fl came with spring/fork suspension, a fuel of 3.75 gallons, a 1 gallon oil and had a top speed of 100 miles per hour. The new valve covers kept oil inside the engine, with the heads reducing operating

The FL’s total weight was 565 lbs a 59.5 inch wheel The cases were modified for for the new and a new camshaft was designed for the new valve Otherwise, the engine’s bottom end was unchanged. Another change for was a reversed gear shift which put the first gear at the and the fourth gear, the front, and inserts for 14mm spark Flight Red, Azule and Black were the FL’s options for the year, and sold for

Close to 13,000 Panheads produced for in their first of production as both E and F models, 8,071 FL’s.

1948 FL FL

Also debuting this was a new lightweight two … 7.6 cubic single, the 125 S model. The new 125 S model with a 2.06 x 2.2 inch and …, had 3 horsepower, a three-speed chain primary and final a 6 volt battery, steel frame, weighted 185lbs, a wheelbase of 50 inches, a fuel of 1.7 gallons, 3.25 x 19 inch with a top speed of 50 miles per The 125cc model S was considered an means of transportation.

The 125 S’s came from Germany’s DKW rights which were after the war. This new 125cc two-… single, came to be known as The Hummer, for $325.00, of which 10,117 built.

were still considered The new addition of their new manufacturing in Milwaukee was used for their of engines and transmissions, and production started to rise again year. 1948 was also the year for the girder/springer front until it’s re-appearance years later, where it was on newer models.

In 1948, won 19 of the 23 National events held, a dominant performance at Daytona in seven of the top 10 that finished Harley Davidson. Production for was 31,163 motorcycles.



Along with a more compliant suspension, skirted one piece seamless were a new addition for 1949. The front forks appeared on the new models, (an FL with telescopic and deeply vanished fenders). The spring tubes gave the a smoother ride and a more look. The hydraulic telescopic forld replaced the girder/springer until they
