Removal

PERFORMANCE ORDER
1) disconnect a wire connecting the storage battery to weight
2) on models with mechanical transmission remove the working cylinder of a hydraulic actuator of coupling and a radiator
3) antifreeze keep for 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 traversy 10-222A into which set the coupling hairpin 3147 enters
7) screw a coupling hairpin 3147 in the top opening for a bolt of fastening of a check point to the engine (М12)
8) attach waists of lifting of the engine according to drawing, lift waists so that the weight of the engine was perceived by only the elevating device

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

 – in the field of a pulley (the left arrow);
 – the third opening in a level of a hook combine with an opening 3 in an elevating beam;
 – from a flywheel (the right arrow);
 – the third opening in a level of a hook combine with an opening 8 in an elevating beam;
 – openings 1–4 in an elevating beam are counted towards an engine pulley;
 – openings in elevating levels of hooks are counted from hooks up.


Prevention

The engine acts in film without a check point.


Do not disconnect:

 – conducting of the working cylinder of a hydraulic actuator of coupling;
 – hoses or a fastening arm from the pump of the hydraulic booster;
 – central air hoses.


Prevention

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

For an insurance зашплинтуйте hooks and probes of an elevating beam (places of a shplintovka are specified by shooters).

When lifting hold the engine not to damage a body.

Installation

Installation of the engine is carried out as it should be the return to removal.
PERFORMANCE ORDER
1) check wear of the vyzhimny bearing of coupling, if necessary replace
2) slightly grease vyzhimny the bearing of coupling and primary shaft of a check point with greasing on the basis of molybdenum sulfide
3) be convinced that aligning pins of joining of the engine with a check point are on the block of cylinders
4) in support of the engine replace самоконтрящиеся nuts
5) lower the engine on support
6) screw самоконтрящиеся nuts of support
7) поманипулируйте the engine (by a kantovaniye) for the correct landing to support
8) adjust a cable of management of a butterfly valve
9) attach all electroconducting
10) fill the engine with cooling liquid
11) check 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 big efforts level in a place of a detail of an exhaust system
