3.1.3. Kinds of the repair work which is carried out without dismantle of the engine

Without dismantle it is possible to replace linings of soaking up and final collectors, a lining of the oil pallet, a head of the block of cylinders, epiploons of a cranked shaft.

It is possible to remove such units as soaking up and final collectors, the oil pallet, the oil pump, the pump of a cooling liquid, a starter, the generator, the distributor of ignition, a mechanism detail газораспределения, units of fuel system and a head of the block of cylinders.

In extreme cases when there is no necessary equipment, without engine removal it is possible to replace piston rings, pistons, rods and шатунные loose leaves. However, to perform these works without dismantle and full dismantling of the engine extremely it is not recommended, as are required clearing of accompanying details, and also carrying out of preparatory measures on assemblage.

It is necessary to notice that mechanism details газораспределения on engines except М40 are expedient for removing after dismantle of a head of cylinders. Engine M40 cam-shaft acts in film without dismantle of a head after removal of covers of basic necks.
