Without dismantle it is possible to replace laying of the oil pallet, a head of the block of cylinders, laying of inlet and final collectors, forward and back covers, an epiploon of a bent shaft.

Without dismantle of the engine it is also possible to remove such hinged units as the pump of cooling liquid, a starter, the generator, the ignition distributor, inlet and final collectors, and also the fuel pump and the carburetor.

As the head of the block of cylinders can be removed without dismantle of the engine too, also repair of the valvate mechanism is possible.
