Repair B3-B4/Passat B3-B4 Volkswagen Passat>> Engines>> Petrol engines of configuration of R4>> Engine assembly Assembly of the engine is carried out in the following sequence:
– establish the block of 17 cylinders (see
fig. 3.27
) a case up;
– clear beds of radical bearings and loose leaves of radical bearings;
– establish loose leaves 3, 5 in a bed of radical bearings. Each loose leaf should be established in that bearing from which it was removed;
– establish persistent half rings 6 central radical bearings;
– grease the established loose leaves with engine oil;
– grease with engine oil all necks of a cranked shaft, including working in contact to epiploons;
– establish a cranked shaft 7 in a bed of the block of cylinders;
– establish loose leaves 3, 5 in covers of 2 radical bearings of a cranked shaft. Each loose leaf should be established in that bearing from which it was removed. On covers of bearings No. 1, 2 and 5 establish loose leaves with a smooth internal surface, on a bearing No. 4 cover – with a flute for greasing. The loose leaf of a cover of the central radical bearing too smooth, on its cover is established by persistent half rings 4;
– establish persistent half rings from two parties of a cover of the radical bearing No. 3. The surface of a persistent half ring with lubricant flutes should be directed outside;
– grease the loose leaf of a cover of the central radical bearing, establish a cover, insert bolts of 1 fastening of a cover and tighten them the demanded moment (see подразд. 3.1.1);
– define axial люфт a cranked shaft (see подразд. 3.1.15);
– grease loose leaves of other radical bearings, establish covers 2, insert bolts of 1 fastening of covers and tighten them the demanded moment;
– turn a cranked shaft manually — it should rotate easily and without breakthroughs;
– establish pistons with rods in collecting (see подразд. 3.1.13);
– turn a cranked shaft manually — it should rotate easily and without breakthroughs;
– establish the oil pump (see подразд. 3.1.12);
– establish a forward cover 15 cranked shaft with new laying 16, tighten bolts 14;
– grease working edges of a forward epiploon 13 cranked shaft and establish an epiploon by means of an opravka
(fig. 3.41)
;
– establish a back cover of a cranked shaft together with new laying of a cover, tighten bolts of fastening of a back cover;
– grease working edges of a back epiploon of a cranked shaft and establish an epiploon by means of an opravka;
– establish the oil pallet (see подразд. 3.1.10);
– overturn the engine and establish it in normal situation;
– put hermetic for the external bottom end of a tube щупа level of oil and establish a tube in the block of cylinders by means of a kiyanka;
– establish a gear pulley 11 (see
fig. 3.3
) on a sock of a cranked shaft;
– block a cranked shaft from a provorachivaniye the long core established between two bolts in a back part of a cranked shaft, and tighten a bolt of the 12th fastening of a gear pulley of a cranked shaft;
– establish an intermediate shaft (see подразд. 3.1.9);
– establish an arm of fastening of the generator and tighten bolts of its fastening;
– turn a cranked shaft of the engine clockwise so that all pistons were established in the middle of the course, thus the piston of the cylinder No. 1 should make a compression step;
– establish laying of GBTs and a head of the block of cylinders (see подразд. 3.1.6);
– establish a forward eye and tighten a bolt of its fastening;
– establish a protective plate 7 (see
fig. 3.3
) and tighten bolts of its 2 fastenings;
– establish hydraulic pushers and a camshaft (see подразд. 3.1.5);
– turn an intermediate shaft so that the groove of a segment shponka was directed up, and establish a segment shponka in a groove;
– establish a gear pulley of an intermediate shaft, tighten a bolt of fastening of a pulley of an intermediate shaft, having blocked it from a provorachivaniye;
– establish a tension roller of a gear belt of a drive of GRM, tighten a nut of fastening of a tension roller so that the axis of a roller turned with effort;
– establish a pulley 9 (see
fig. 3.3
) a cranked shaft, fix it on a diagonal two bolts;
– turn a camshaft in the situation corresponding to position of the piston of the cylinder No. 1 in VMT, i.e. before label combination on a pulley with the plane of a head of the block of cylinders (see
fig. 3.5
);
– establish the cylinder No. 1 piston in VMT turn of a cranked shaft clockwise;
– combine labels on pulleys of intermediate and cranked shaft turn of an intermediate shaft (see
fig. 3.4
);
– establish a gear belt of a drive of GRM and check its tension (see подразд. 3.1.4);
– unscrew bolts of fastening and remove a pulley 9 (see
fig. 3.3
), previously having noted its situation;
– check laying existence in the bottom cover of the 10th belt of a drive of GRM, establish a cover 10 and tighten bolts of fastening of a cover;
– establish a pulley 9 cranked shaft on the put labels and tighten bolts of fastening of a pulley;
– establish laying 12 (see
fig. 3.8
) and a cap 13 on a head of the block of cylinders;
– establish new laying of the 5th cover of a head of the block of cylinders;
– establish a maslootrazhatel 4;
– establish a cover of the 6th head of the block of cylinders and power strips 7;
– establish the top protective plate 3 (see
fig. 3.2
);
– establish the top cover of 1 belt of a drive of GRM;
– establish an intermediate plate on adjusting pins of a back part of the block of cylinders;
– establish a flywheel or a leading disk (see подразд. 3.1.8);
– establish auxiliary units on the engine.
If hydraulic pushers were replaced, do not start up the engine within 30 minutes. This time is necessary for an exit from a pusher of superfluous oil, valve and piston impact otherwise is possible.
