Made any progress on this?

Is it locked up or one legged so one wheel gets power and the other does not. The rear end in this trike I’ve been building looks the same but it’s locked up like a posi. So it’s impossible to drive with these tires, bolth wheels spin at the same time. Do you know anything about these rear ends because I don’t

Servi-car Axle
"...final drive on the Harley-Davidson Servi-car is a simple chain-drive mechanism. A chain attaches the transmission output gear to the rear drive sprocket and both rear wheels rotate at the same speed. This final-drive system was cheap to manufacture and very durable...

Differences In Servi-car Rear Axles

Early Servi-car axles (1934 to 1936) have a big center, with a single mechanical drum brake inside the housing. This brake has two shoes and is internal-expanding on a fixed pivot. A parking brake is mounted inside the rear axle housing.

In 1937, the Servi's brake system was upgraded to a drum brake on each rear wheel. Somewhere in the 1940s, the axle halves were welded together instead of riveted.

The 1941 to 1950 rear axles are slightly different than 1951-1972 units. They will fit up to 1972, but not be "correct".
Last-year Servi-cars (1973) were disc-brake equipped and had six-stud wheels...
