The engine assembled of cylinder head (2) and crankcase (1), and the gear box (3) are inserted as a unit through the gap between the longitudinally positioned carrying profiles (4, 5) from below. Each of the profiles (4, 5) is fitted with a bearing (6, 7) added from above and screwed to the unit (1, 2, 3). The bolt (9) used for joining the engine unit (1-2) to the bearing (6) is horizontally inserted through a bore (11) located at the wheel-case (10). The bearing (6) is of an extremely slim shape in order to save space for the accommodation of a wide engine unit.
