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


Without dismantle it is possible to replace laying of soaking-up and final collectors, laying 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 cooling liquid, a starter, the generator, the distributor of ignition, a detail of the mechanism of a gazoraspredeleniye, units of fuel system and a head of the block of cylinders.

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

It should be noted that details of the mechanism of a gazoraspredeleniye on engines except М40 are expedient for removing after dismantle of a head of cylinders. The cam-shaft of the M40 engine acts in film without head dismantle after removal of covers of basic necks.
