Removal of a cranked shaft is carried out in the following order:

– remove the power unit from the car (see подразд. 3.2.4);

– disconnect a transmission from the engine;

Drive of auxiliary units: 1–pulley of a cranked shaft; 2–pulley of the water pump; 3–tension roller; 4–mechanism of a tension of a belt of a drive of auxiliary units; 5–generator pulley; 6–pulley of the compressor of the conditioner; 7–pulley of the hydraulic booster of a steering; 8–belt of a drive of auxiliary units

– unscrew a bolt of fastening of a pulley 1 (fig. 3.53) of a cranked shaft and remove a pulley;

– unscrew bolts of fastening of a pulley of the water pump and remove a pulley 2;

– remove chains of a drive of GRM;

– remove a head of the block of cylinders (see подразд. 3.2.5);

– remove the oil pallet;

– remove the oil pump;

– remove pistons with rods in collecting (see подразд. 3.2.7);

– measure axial люфт a cranked shaft with the help щупа (see подразд. 3.1.15) or indicator of hour type. Axial люфт a cranked shaft regulate persistent half rings 3 (see fig. 3.52 ) which are established in the case of the radical bearing No. 5;

Forward and back covers of a cranked shaft, oil pallet: 1–cap of the oil channel; 2–block of cylinders; 3–cover of a drive of GRM; 4–bolt of fastening of a back cover of a cranked shaft; 5–back cover of a cranked shaft; 6–back epiploon of a cranked shaft; 7–laying of the oil pallet; 8–oil pallet; 9–stopper of a masloslivny opening; 10-bolt of fastening of the oil pallet; 11-forward cover of a cranked shaft; 12-bolt of fastening of a forward cover of a cranked shaft; 13-forward epiploon of a cranked shaft

– unscrew bolts 12 (fig. 3.54) of fastening of a forward cover of a cranked shaft and uncover 11 together with a forward epiploon 13;

– unscrew bolts of 4 fastenings of a back cover of a cranked shaft and uncover 5 together with a back epiploon 6;

– mark covers of radical bearings for the subsequent their correct installation;

– unscrew bolts of fastening of covers of radical bearings and remove covers, without taking from them loose leaves;

– remove a cranked shaft;

– remove the top loose leaves of radical bearings (loose leaves of beds of a cranked shaft) and mark them for the subsequent correct installation.

The top loose leaves have a flute for supply of greasing to a cranked shaft.

Fault detection of a cranked shaft is carried out in the sequence described in подразд. 3.1.16.

Controllable parameters are specified in подразд. 3.2.1.

Installation of a cranked shaft is carried out in the following order:

– establish the block of cylinders 2 (see fig. 3.54 ) a case up;

– clear working surfaces of the top loose leaves of radical bearings and grease them with fresh engine oil;

– establish the top persistent half rings 3 (see fig. 3.52 ) the radical bearing No. 5;

– grease all necks of a cranked shaft with 1 fresh engine oil;

– establish a cranked shaft in the block of cylinders;

– establish loose leaves 4 in radical bearings;

– establish persistent half rings 3 in a cover of the radical bearing No. 5;

– establish covers of radical bearings and tighten bolts of fastening of covers the moment of 30 N · m, then tighten them on a corner 180 °;

– turn a cranked shaft manually. It should rotate easily, without breakthroughs;

– check axial люфт a cranked shaft (see подразд. 3.1.15);

– establish pistons with rods assembled;

– establish forward and back covers of a cranked shaft with new epiploons;

– establish a flywheel;

– establish the oil pump;

– put hermetic on surfaces of contact of the block 2 (see fig. 3.54 ) cylinders and the oil pallet 8;

– establish laying 7 oil pallets;

– establish the oil pallet 8 and tighten bolts of the 10th fastening of the oil pallet the moment of 20 N · m cross-wise, beginning from an average part of the pallet;

– execute other operations in sequence, return to removal.
