A Quick Look at the Harley 45
Harley-Davidson first showed its 45 " (750cc), 4 camshaft, 45-degree V-twins (labeled 45) in 1929 and officially called this model the DL. This motorcycle has a vertical generator that's powered with a helical gear.
Harley released a customized model in 1932 known as RL, which includes a generator that's concurrent with the bottom. In 1937, Harley-Davidson began developing the revised WL, which has a re-circulating petrol mechanism. All previous 45s have total loss oiling systems. These motorbikes specified for mild biking and have a top acceleration of 55 or 60 mph, dependant upon the gear weight. In 1939, Harley-Davidson started changing its motorcycles to match US military needs, creating a bike for the Army before the United States was even in the war.
At first glance, there are a lot of variations that stand out on a civilian WL as well as the military WLA. The WLA is equipped with a gun scabbard, an ammo pack, lower leg shields, a skid plate, large bags, a rugged baggage rack, and tall mounted side mirrors. While these are generally some of the evident variances, there are a variety of more understated improvements. Even though the fundamental form of the WLA matches a private Harley-Davidson 45, almost all of the components are different when compared with their civilian counterparts. For example, one of the biggest concerns with the US military versions was being discovered by attack planes. The fix for this matter was to outfit the motorbikes with blackout equipment. The front light features a steel cover over the reflector and lens with a small hood emerging from the top allowing a beam of light to shine in front of the bike; it is usually seen at on the ground but not from above. Equivalent lights were installed at the back of the motorbike for brake lights and tail lights. The dash lights, which are alerting lights to tell the biker if he has an issue with the charging system or if perhaps the essential oil is not recirculating, are also blacked out. Rather than regular lenses, they get black lenses with some 0.090" hole punctured on them, so if mechanism fails and the warning lights came on, an aircraft wouldn't find them, but the driver could.
The WLA motor is pretty much like the standard edition WL, with some minimal variances. The heads have reduced compression versions, additionally, the return oil pump has a little fitting for an oil tube that flows to the back chain. The carburetor incorporates a preset, fast speed needle to protect the bike from some farm youngster power-tuning the motorcycle and busting the motor. The standard copper fine mesh air filter was replaced with an oil bath air cleaner, which is similar to the filter design and style employed on semi-trailers.
And also the tires are made from various rubber. As a result of material shortages during the conflict, tires and other rubberized parts were made of an artificial rubber chemical substance. Anything from vehicles to tractors had to start using these tires in order to support the war effort. Interestingly, WLAs yet used rubber hand-grips similar to the pre-war private motorcycles. The rubber foot-board mats were substituted with steel mats around 1943.
More alterations include the oil tank and gas tank, which are equipped with additional drains and bungs. The fenders had the skirts taken off and so mud and dirt could easily be cleaned off the tires. And also the seat was modified to become a stronger and tougher part. The seat pan comes with an extra bit of steel on the outside lip and about three rivets which go through the cover to secure the seam from ripping in the event the motorbike tips over.
The moment the war ended, Harley-Davidson had created over 70,000 motorcycles for the war effort, not to mention the countless numbers of various other spares to keep the motorcycles running. These H-Ds are fantastic bikes that did their efforts to win the war.
