Cover

Made of grey cast iron according to GOST 1412-85 by casting and milling on a CNC machine. Often called the upper half of the gearbox housing. The cup TSN.00.133 is mounted on this cover. Together with a pair of TSN.02.101, it forms an oil bath for the gearbox gears. The gearbox TSN.02.020 is often mistakenly numbered as TSN.02.102 because of the clearly visible product code on the cast part.
