Harley Davidson Flathead WLC - 1942

The Great Depression began a few months after the introduction of their 45 cubic inch model. Harley-Davidson's sales plummeted from 21,000 in 1929 to 3,703 in 1933. Despite those dismal numbers, Harley-Davidson proudly unveiled its lineup for 1934, which included a Flathead with Art Deco styling.[21]

In order to survive the remainder of the Depression, the company manufactured industrial powerplants based on their motorcycle engines. They also designed and built a three-wheeled delivery vehicle called the Servi-Car, which remained in production until 1973.[18]

In the mid-'30s, Alfred Rich Child opened a production line in Japan with the 74ci VL. The Japanese license-holder severed its business relations with Harley-Davidson in 1936 and continued manufacturing the VL under the Rikuo name.[22]

An 80 cubic inch flathead engine was added to the line in 1935, by which time the single-cylinder motorcycles had been discontinued.[23]

In 1936, the 61E and 61EL models with the "Knucklehead" OHV engines was introduced.[24] Valvetrain problems in early Knucklehead engines required a redesign halfway through its first year of production and retrofitting of the new valvetrain on earlier engines.[25]

By 1937, all Harley-Davidson's flathead engines were equipped with dry-sump oil recirculation systems similar to the one introduced in the "Knucklehead" OHV engine. The revised 74 cubic inch V and VL models were renamed U and UL, the 80 cubic inch VH and VLH to be renamed UH and ULH, and the 45 cubic inch R to be renamed W.[24]

In 1941, the 74 cubic inch "Knucklehead" was introduced as the F and the FL. The 80 cubic inch flathead UH and ULH models were discontinued after 1941, while the 74" U & UL flathead models were produced up to 1948.
