5.3.2. Removal and installation of a gear drive of the mechanism of a gazoraspredeleniye

When using earlier working belt note the direction of its movement before starting removal. Establish a driving belt on the labels made at removal.
Disconnect the "minus" plug of the storage battery. To "Poddomkratta" a forward part of the car on the right side also establish a support. Remove a wheel, a mudguard and the bottom board of protection of a case of the engine. Merge liquid from cooling system. Weaken fastening of a pulley of a drive of the water pump. Remove through an arch of the right wheel the top branch pipe of a radiator of system of cooling of the engine. Remove driving belts of auxiliaries, a pulley of a drive of the water pump, the top part of a cover of a drive of the mechanism of a gazoraspredeleniye and take laying. Establish to an emphasis under the engine or застропите the engine for eyes. Remove the right arm of an engine mount. Disconnect the electricity cables suitable to a starter, and then a starter. Turn a cranked shaft and establish cut of a pulley of a cranked shaft (without color marking) against a label on the block of cylinders (the piston of the 1st cylinder is in VMT of a step of compression).
Turn a cranked shaft clockwise for a bolt of fastening of a pulley of a cranked shaft or the lifted forward wheel after inclusion of IV or V transfers.

by means of the KV 10105630 adaptation


Establish instead of an adaptation (KV 10105630 and KV 101105610) starter for flywheel blocking from rotation (fig. 3.15). Unscrew a bolt of fastening of a pulley of a cranked shaft, then by means of a stripper with captures for external gearing remove a pulley. Remove the lower part of a cover of a drive of the mechanism of a gazoraspredeleniye and take laying. Weaken a bolt of a tension roller and turn a roller counter-clockwise for weakening of a tension of a driving belt. Tighten a bolt of a tension roller. Remove a flange of a gear pulley of the camshaft, directing roller, a driving belt of a camshaft. Take out a segment shponka and remove a maslootrazhatel (on the CD20 engine).
After removal of a driving gear belt do not allow turn of cranked and distributive shaft to avoid blow of valves about pistons.
At replacement of a driving belt of the mechanism of a gazoraspredeleniye it is recommended to replace tension and driving rollers also. If rollers are not replaced, be convinced that they rotate without jammings.

Fig. 3.17. Installation of the mechanism of a gazoraspredeleniye on labels: 1 — a bolt of fastening of a tension roller; 2 — a natural an external shestigrannik for compression of a spring of a tension roller; 3 — a shponka of a cranked shaft in situation «12 hours»; 4 — a label on gear to a pulley of a cranked shaft in situation «3 hours»; 5 — a label on gear to a camshaft pulley in situation «3 hours»


At installation of a driving belt observe the direction of installation specified by shooters on a belt. Check a condition of an epiploon of a forward support of a cranked shaft. If necessary replace an epiploon. For a vypressovka of an epiploon use an opravka of the corresponding diameter. Put a greasing layer between forward edges of an epiploon. Be convinced of purity and absence of damages on surfaces of gear pulleys and the rollers adjoining to a driving belt. Establish a maslootrazhatel of a pulley of a cranked shaft (on the CD20 engine), observing the installation direction (fig. 3.16), and a segment shponka. Be convinced that the shponka of a cranked shaft is in situation «12 hours», and cut on a gear pulley of a camshaft is in situation «3 hours» (fig. 3.17). Establish directing roller, then a driving belt with a pulley on a cranked shaft so that labels on pulleys of cranked and distributive shaft were in situation «3 hours». Adjust a tension of a branch of a driving belt between two gear pulleys. Focus arrows on a gear driving belt aside from the engine. Establish a flange of a gear pulley of a camshaft and put on bolts of fastening of a flange a layer of kontrovochny paste. Unscrew a nut of a tension roller for spring release. Turn a cranked shaft of the engine on two turns clockwise, then return it to the provision of an initial corner of an advancing of injection for installation check.
Do not rotate a cranked shaft of the engine for a gear pulley of a camshaft.
Tighten a nut of a tension roller, holding a roller from rotation by means of a natural an external shestigrannik. Other operations on installation of a belt are carried out as it should be, the return to removal. Fill with liquid system of cooling of the engine and remove from it air.
