4.9.2. Features of assembly of engines


Sequence of an inhaling of bolts and nuts of hairpins of fastening of covers of radical bearings


1 – forward part of the engine

Installation of a cover of a back cuff of engines mod.331, 3317 and 3313 by means of a mandrel


Check of a vystupaniye of an end face of a sleeve of cylinders over the plane of the block of engines mod.331, 3317 and 3313



Relative positioning of locks of piston rings before installation of the piston in a sleeve

Before assembly of the engine it is necessary to make the following actions:

PERFORMANCE ORDER
1. Inserts of bearings and persistent half rings of a bent shaft, and also pistons and cuffs need to be oiled engine.
2. To lay in nests of the block of cylinders and in the corresponding covers inserts of radical bearings.
3. To lay in radical bearings a bent shaft with a gear wheel of the drive of the oil pump, the leading asterisk of the camshaft and the bearing of a main shaft of the transmission and to insert two persistent half rings into nests of an average cover of radical bearings.
4. The allowed axial side play cranked a shaft of 0,1-0,29 mm (at an axial side play of 0,35 mm and more – to replace half rings new).
5. To establish covers of radical bearings with the lower inserts according to tags and to evenly tighten nuts of hairpins of radical bearings. To make a final inhaling a dynamometer key according to rice. Sequence of an inhaling of bolts and nuts of hairpins of fastening of covers of radical bearings. Moment of an inhaling of 90-100 N · m (9–10) kgfs · m.
6. To impose laying of a cover of a cuff on a back flange of the block of cylinders. To put on a cover with a cuff a mandrel (fig. Installation of a cover of a back cuff of engines mod.331, 3317 and 3313 by means of a mandrel) and, having moved a cover from a mandrel on a flange of a bent shaft, to attach it bolts to the block of cylinders. To make centering of a cover with a cuff in relation to a flange of a bent shaft on three special ledges on a cuff cover.
7. To establish a flywheel on a bent shaft. Before a wraparound of bolts to enclose under them three lock plates (on one under two bolts). To wrap bolts and to bend the ends of lock plates so that to exclude a possibility of an otvorachivaniye of bolts. To make a final inhaling of bolts a dynamometer key. Moment of an inhaling of 70-80 N · m (7–8 kgfs · l)
8. To insert sleeves into boring of the block of cylinders and to check sleeve end face vystupaniye size over the block plane (fig. Check of a vystupaniye of an end face of a sleeve of cylinders over the plane of the block of engines mod.331, 3317 and 3313). The size of a vystupaniye has to be within 0,01–0,08 mm. To make check in caliber, predvaritelna having pressed a sleeve to the block with effort of 5-7 kgfs. Before installation of sleeves it is necessary to clear especially carefully of a scum and products of wear end faces of nests under sleeves in the block and landing end faces on sleeves.
9. To make final installation of a sleeve after installation in it
the piston with rings and a rod assembled.
10. After check of a vystupaniye to take out sleeves from the block and to install in them pistons with rings and rods assembled. Before installation of the piston with rings and rods assembled in a sleeve to oil piston rings, a skirt of the piston and a piston finger for the engine. To make installation of piston rings so that their locks settled down at an angle 120 ° rather each other (fig. A relative positioning of locks of piston rings before installation of the piston in a sleeve). Before installation of the piston with rings in a sleeve to squeeze rings special snap.
11. Before final installation of sleeves to grease with nitropaint their landing surfaces.
12. At installation of a sleeve in the block of cylinders to pay special attention to correctness of an arrangement of the piston and a rod. An arrow on the piston bottom, a ledge on a core of a rod and a groove on a cover of a rod have to be turned towards chain transfer of the drive of the camshaft.
13. To establish inserts in rods and covers of rods, previously having oiled them engine and to connect rods to necks of a bent shaft, to establish covers and to evenly tighten nuts of conrod bolts. To make a final inhaling a dynamometer key. Moment of an inhaling of 55-65 N · m (5,5–6,5 kgfs · м).
14. To check whether the bent shaft in bearings easily rotates, previously having fixed sleeves by levels holders (see rice. Fixing of sleeves of cylinders of engines mod.331, 3317 and 3313).
15. To remove levels holders of sleeves from hairpins of fastening of a head of cylinders and to establish on hairpins sealing laying and a head of cylinders with an inlet pipe, a final collector and the fuel pump assembled.
16. To replace the damaged or strongly pressed out sealing laying new.
17. To grease laying of a head of the block from two parties with a thin layer of graphite lubricant.
18. To make an inhaling of nuts of fastening of a head of the block of cylinders in the sequence specified rice. An order of an inhaling of nuts of hairpins of fastening of a head of the block of cylinders to the block of the engine of fashion. 331, 3317 and 3313. To make a final inhaling a dynamometer key. Moment of an inhaling of 90-100 N · m (9–10 kgfs · м).

Before installation of a head of the block of cylinders assembled it is necessary to make the following actions:

PERFORMANCE ORDER
1. To turn a bent shaft so that the piston of the first cylinder was in the provision of VMT.
2. The camshaft has to be turned so that risk on its flange coincided with the middle of inflow on a forward support of the camshaft.
3. To wring out an asterisk of the tension device and to throw with a chain the leader and conducted camshaft drive asterisks; to establish the conducted gear wheel together with a chain on a .raspredelitelny shaft so that the leading branch of a chain did not sag.
The top cover of distributive asterisks is established after fixing of the lower cover, besides, the plunger of the tension device has to be previously drowned in a cover. To make an inhaling of bolts of a cover in the sequence specified in the drawing.
4. To release a lock bolt of the tension device on 0,5–0,75 turns.
5. To establish a pulley and a lock washer of a ratchet on a sock of a bent shaft and to tighten a ratchet a dynamometer key. Moment of an inhaling of 80-90 Nanometers (8–9 кгс.м). Then to bend a lock washer.
6. To turn a bent shaft clockwise on 2–3 turns with the released lock bolt of the tension device for the choice of all gaps in the camshaft drive then to wrap a lock bolt (1) against the stop.
7. To install the ignition distributor drive on the engine (see subsection 4.5).
8. To establish into place an oil case with laying. If a condition of laying of an oil case unsatisfactory (laying is compressed or damaged) to replace it new. To make an inhaling of screws and nuts of fastening of an oil case in the sequence specified in the drawing.
9. To establish a cover of a head of cylinders with laying. If a condition of laying of a cover of a head of cylinders unsatisfactory, it is necessary to replace laying new.
10. When carrying out repair of the engine of the car having a run more than 60000 km it is recommended to change piston rings and connecting rods.
11. When replacing the hairpins leaving in a cavity of a water shirt, and also laying of a cover of a water shirt of the block of cylinders to establish them on zinc whitewash.
