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

Removal

PERFORMANCE ORDER
1) disconnect the wire connecting the rechargeable battery to weight
2) on models with mechanical transmission remove the working cylinder of a hydraulic actuator of coupling and a radiator
3) keep antifreeze for further use
4) remove the pump of the hydraulic booster of steering and attach to a body
5) turn out bolts of fastening of the compressor, remove an arm and displace it aside
6) record the check point from falling traversy 10-222A in which package the coupling hairpin 3147 is included
7) screw a coupling hairpin 3147 in the top opening for a bolt of fastening of the check point to the engine (M12)
8) attach waists of raising of the engine according to the drawing, raise waists so that the weight of the engine was perceived only by the lifting device

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

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


Prevention

The engine is removed without check point.


Do not disconnect:

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


Prevention

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

For an insurance to a zashplintuyta hooks and probes of a lifting beam (places of a shplintovka are specified by shooters).

At rise 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 release bearing of coupling, if necessary replace
2) slightly grease the release bearing of coupling and a main shaft of the check point with lubricant on the basis of molybdenum sulfide
3) be convinced that the aligning pins of joining of the engine with the 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) to a pomanipuliruyta the engine (by a kantovaniye) for the correct landing to support
8) adjust a cable of management of a butterfly valve
9) attach all electrical wiring
10) fill the engine with cooling liquid
11) check and if necessary restore oil level
12) adjust a tension of a gear belt of the drive of a cam-shaft and turns of idling
13) without using great efforts level in the place of a detail of the exhaust system
