Order of dismantling of the engine by its preparation for carrying out major maintenance

It is simplest to make dismantling and engine service after its installation on the portable assembly stand. Such stands always can be rented in a car-care center workshop. Before engine installation on the stand it is necessary to remove from it a flywheel / a driving disk that fixing bolts could be screwed in a face surface of the block of cylinders.

In the absence of possibility of use of the assembly stand it is necessary to take care of arrangement of a strong metalwork workbench. As a last resort, dismantling and repair of the engine can be made on a garage floor. Prepare also pair of strong wooden blocks for engine installation on them. In case of works without use of the stand try not to strike on the engine and not to drop it.

If you managed to get the restored engine, it is necessary to rearrange on it with old all hinged units and components. Into number of such components enter:
   a) Bearing arms of the generator;
   b) Arms of the hydraulic pump and the To/in compressor (at the corresponding complete set);
   c) The thermostat in a casing with final a chamber/knee - petrol models (see. Head of System of cooling, heating);
   d) Assembly of a fuel filter/casing of the thermostat - diesel models;
   e) Directing tube measuring щупа;
   f) Power supply system components (see. Head of the Power supply system and release);
   g) All electric sensors and switches;
   h) The inlet pipeline and a final collector (see. Head of the Power supply system and release);
   i) The oil filter (address to Head Routine maintenance);
   j) Flywheel / driving disk.

At dismantle from the engine of hinged units and components pay attention to characteristic details of their installation which can be useful as reference points at assembly. Try to remember an order of installation of laying, epiploons, remote rings and plugs, pins, washers, bolts and so forth.

If there is a possibility of acquisition of the reduced set of the engine consisting of the block of cylinders, a cranked shaft and rods with pistons (all assembled), it is necessary to remove from the old unit also a head of cylinders, the case pallet, the oil pump and a gas-distributing belt.

By preparation for performance of complete major maintenance dismantling of the engine is recommended to be made in the following order (see appropriate section of the present Chapter if other addressing is not given in brackets):
   a) The inlet pipeline and a final collector (see. Head of the Power supply system and release);
   b) A belt of a drive of GRM with cogwheels and a natyazhitel (hole);
   c) Head of cylinders;
   d) Flywheel / driving disk;
   e) Case pallet;
   f) Oil pump;
   g) Shatunno-porshnevye assemblies (see. Removal of shatunno-piston assemblies);
   h) A cranked shaft (see. Removal of a cranked shaft).

Before the beginning of dismantling of the engine and its preparation for major maintenance make sure available all necessary tools and materials. More detailed information is stated in the section Tools and the workplace equipment.
