An open differential assembly. A 12T pinion drives a 50T straight bevel ring gear (module 2) at 90°. The ring gear is bolted with 8×M6 to a carrier that holds two 10T spider gears on a Ø10 cross pin and two 16T side gears with Ø20 splined bores. The carrier hubs run in two 6006 bearings inside a split outer casing that has an oil filler plug.
