2.1.1. Removal and engine installation (4-cylinder models)

Removal

PERFORMANCE ORDER
1) disconnect a wire connecting the storage battery with weight
2) on models with mechanical transmission remove the working cylinder of a hydrodrive of coupling and a radiator
3) antifreeze keep for the further use
4) remove the pump of the hydraulic booster of a steering and attach to a body
5) turn out bolts of fastening of the compressor, remove an arm and displace it aside
6) fix a check point from falling траверсой 10-222А which complete set includes a coupling hairpin 3147
7) screw a coupling hairpin 3147 in the top aperture for a bolt of fastening of a check point to the engine (М12)
8) attach тали engine lifting according to drawing, lift тали so that the engine weight was perceived only by the elevating device

Places of fastening elevating the traverses, had with understating to a back part of the engine:

 – In the field of a pulley (the left arrow);
 – The third aperture in a hook lath combine with an aperture 3 in an elevating beam;
 – From outside a flywheel (the right arrow);
 – The third aperture in a hook lath combine with an aperture 8 in an elevating beam;
 – Apertures 1–4 in an elevating beam are counted towards an engine pulley;
 – Apertures in elevating laths of hooks are counted from hooks upwards.


The prevention

The engine acts in film without a check point.


Do not disconnect:

 – Conducting of the working cylinder of a hydrodrive of coupling;
 – Hoses or an arm of fastening from the hydraulic booster pump;
 – Central air hoses.


The prevention

At replacement of the engine, a head of the block of cylinders, linings of a head of the block, a radiator and the heater heat exchanger, the cooling liquid is subject to replacement.

For the insurance зашплинтуйте hooks and probes of an elevating beam (places шплинтовки are specified by arrows).

At lifting keep the engine not to damage a body.

Installation

Engine installation is carried out as it should be the return to removal.
PERFORMANCE ORDER
1) check up deterioration выжимного the coupling bearing, if necessary replace
2) slightly grease выжимной the bearing of coupling and a primary shaft of a check point with greasing on the basis of molybdenum sulphide
3) be convinced that aligning pins of joining of the engine from a check point are on the block of cylinders
4) in engine support replace самоконтрящиеся nuts
5) lower the engine on support
6) screw самоконтрящиеся nuts of support
7) поманипулируйте the engine (a way кантования) for correct landing to support
8) adjust a cable of management throttle заслонкой
9) attach all electroconducting
10) fill the engine with a cooling liquid
11) check up and if necessary restore oil level
12) adjust a tension of a gear belt of a drive of a cam-shaft and idling turns
13) without putting the big efforts level in a place of a detail of an exhaust system
