The weight of the TD42T engine according to the catalog is 365 kg. The TD42T engine number is located at the junction of the block and the cylinder head. The outstanding reliability of the engine is overshadowed by strong vibrations and noisy operation. In severe cold weather, it can shear the drive splines of the vacuum pump on the generator. The oil pressure sensor is more prone to failure in the engine's electrical system, as it is sensitive to moisture. Periodically, leaks from the gasket of the gear housing and water pump are found here. Poor fuel causes detonation, which can cause cracks in the swirl chamber walls.
