Disassembly and assembly of the cylinder components of the service
 | Removing and installing the crankshaft and the connecting rod and piston assembly can be performed without removing the engine from the car. |
Dismantling The design of the cylinder (see. Also graphic details the installation of a flywheel / disk drive)  | | |
| - Remove the engine (see. Section systems of electric motor).
- Remove the cylinder head (see. Section Maintenance of the cylinder head and camshaft components).
- Remove the oil pump (see. Section Removal, installation and maintenance of the oil pump).
- Remove the pan and flywheel / drive plate (see. Section Removal and installation of the oil pan).
- Remove the rear oil seal with a lid (see. Section Replacing crankshaft seals).
- Turn out fixing bolts and remove the crankshaft bearing caps to the collection with inserts.
- Turn out fixing bolts and remove the bottom head first rod assembly to the liner. Uprites in the head of a rod and a hammer handle, pushing the connecting rod and piston assembly up and remove it from the cylinder.
- Operating in a similar manner, remove the remaining assembly.
- In order to prevent confusion when checking the status of the components immediately set to their former places of covers of rods and the crankshaft bearing assembly with insert and secure them with fixing bolts.
- With inertial puller remove the pin installed in the rear of the crankshaft guide bearing (see.

|
Service | - Carefully review the status of the casting unit. Check each cylinder for cracks, burrs, and other mechanical damage.
- Acting in a manner similar to that described in Section Disassembly and assembly of the cylinder components of the service, evaluate the degree of violation of the flatness of the mating surface of the cylinder head unit (see. If necessary, replace the unit.
 | Restoration of the flatness of the surface of the mating block by machining it in any case is not admissible! |
- Bullies cylinder bores can be machined to the corresponding repair size, if such a treatment is not possible, replace the unit.
 | - Measure the diameter of each of the cylinders on three levels and in both directions, that will reveal defects such as taper and roundness. If the measurements exceed the maximum permissible value (see. Specifications of the Head of engine), the cylinders should be chiseled to the nearest repair size. In conclusion, the mirror must be othoningovany cylinders, - act in accordance with the instructions supplied with the special honingovochnym sets.
|
 | - Special countersink delete step deterioration of cylinders, leave the top compression ring to the end of the stroke.
|
- Remove the retaining ring, remove the piston pins and make the dismantling of pistons with rods.
- Examine the condition of the piston, in the case of detection of cracks, burrs, and other mechanical damage, prepare a replacement.
 | - Measure the diameter of each piston in a direction perpendicular to the piston pin axis and at a distance of 18 mm from the lower edge of a groove for setting scraper ring. By comparing the measurement result with the value of the diameter of the corresponding cylinder, determine the value of the landing backlash. If the play exceeds the limit, replace the piston cylinder is machined to the nearest repair size.
|
| Simultaneously, the piston must be replaced as piston rings (the corresponding repair size - see. Specifications of the Head of Engine). |
- Check the piston rings for signs of excessive wear, cracks, chips and other mechanical damage. If necessary, replace.
- Alternately tucking the piston rings into the cylinder and pushing them to the bottom of the piston to the bottom of the latter (BDC position of the piston), measure the magnitude of backlash in the lock rings (see. Compare results of measurements to requirements of Specifications of the Head of engine, if necessary, chisel locks, or replace the rings.
- Measure the backlash of landing rings in the grooves of the pistons (see. if necessary, replace the ring / piston.
| Measurement should be performed at several points of the perimeter of the groove. Since then, the rings must be "attached" to their piston / cylinder. |
- At a special stand believe rods for signs of bending and twisting (see. If you exceed the measurements the limit value, replace defective components.
 | - Measure the diameter of the piston pin for planting in the pistons. Record the measurement results.
|
 | - Measure the diameter of the piston pin in the places of pressing in the plunger.
|
- By subtracting the results of the first measurements of the results of the second define play / interference fit fingers in the pistons.
- By measuring the corresponding diameter piston pins and holes in the top heads of rods determine backlash planting fingers rods. If you exceed the results of computing the limit value, replace connecting rods.
- Carefully review the state of the crankshaft. Check it out root and crankpins for scoring, signs of overheating and other mechanical damage. Make sure that there are no violations patency oil holes.
- Having laid the shaft prism, check for bending using the meter DTI (see.
- Measure the diameters of the necks, estimate the value of their taper and roundness. If deterioration of necks exceeds the limit, pierce them at the closest repair size (do not forget to choose the appropriate size ear reconstruction), or replace the shaft.
| In no case did not cut the necks of rounding, - the minimum allowable radius of curvature of 2.6 ÷ 3 mm. |
- Examine the condition of bearings. In case of defects, prepare a replacement kit. Arrange shells in order of their installation on the engine.
|
|
Assembly | - Before assembly, make sure of absoluteness of cleanliness of all components.
 | - Properly position the piston rod relative.
|
- Grease with pure motor oil hole in the piston and the top head of a rod.
- By means of special tongs plant circlip in the groove in one of the openings of the piston, then fill the last upper head rod.
 | - Through a suitable mandrel carefully zastuchite piston pin, fixing the piston to the connecting rod. Fix the second retaining ring finger.
|
- Operating in a similar manner, the remaining mount the connecting rod and piston assembly.
- Put on the pistons, piston rings previously selected first in the bottom groove of the piston is set pre-oiled oil ring expander, then infest its working section (scrapers).
| Scrapers scraper ring identical in construction and does not require the uniqueness of landing during installation. |
 | - Further, in the remaining grooves are filled and generously lubricated the lower and upper compression ring (do not confuse the ring - they differ in shape cross-section), - track correctness of placing rings - they must be installed marked with letter ?�R?� side up.
|
 | - Expand the piston rings on fitting locks in these areas.
|
- Put the cylinder block Lubricators and tighten bolts of their fastening with demanded effort (12 ÷ 18 Nm).
 | - Carefully wipe the neck of the crankshaft main bearing shells back and the bed in the unit completely removing traces of oil from them. Insert liners and install the shaft.
|
| Persistent is the central main bearing. |
- Once again, wipe the main journals of the shaft, lay along them Gauging Plastic Plastigage set out to define the working backlashes in bearings.
| Make sure that the wire is laid over the oil holes necks! |
 | - Wipe the back of the bearing shells and bed covers, then install the latest, having tracked correctness of placement and, acting strictly in a certain order, tighten bolts of their fastening with demanded effort.
|
 | - Release the fasteners, remove the cap and measure the width of the flattened wire on the scale printed on the box set Plastigage, determine the value of backlashes in radical bearings.
|
| During the test, do not turn the crankshaft! If the measurement exceeds the limit, make a selection of new pads, if necessary pierce the shaft to the appropriate oversize and install repair the ear. |
- Having finished check, lubricate working surfaces matched inserts and indigenous shaft neck clean motor oil, put the shaft in the block.
- Install the crankshaft bearing caps, push the shaft forward until it stops, then turn it back and tighten the cover bolts with demanded effort.
 | - Check the axial play of the crankshaft and the freedom of its rotation. Compare result of measurement to requirements of Specifications of the Head of engine, if necessary, choose a new thrust bearing.
|
- Using a suitable mandrel, put a pin on the back of the shaft guide bearing (see. - do not forget to lubricate the bearing and the pin of the motor oil. After installing tamp bearing grease.
- Carefully thread the connecting rod and piston assembly into its cylinders: piston wall and mirrors of cylinders before installation should be lubricated with clean motor oil, piston rings compress special mandrel; pushing the pistons in the cylinders is better to make the handle of a hammer. Make sure that the pistons have been established labels in the form of letters ?�F?� forward on the engine.
| In the event of resistance, stop pushing the plunger, remove the assembly and ensure the completeness of the removal of step deterioration in the upper part of the cylinder! |
- By planting the lower head of rods to the crank pin shaft, make a measurement of working backlashes in connecting rod bearings - act in a manner similar to that described above for the main bearings. Remember that when checking bearing shells must be installed on the dry, track correctness arrangement covers.
- With the probe blade-type metering make the axial backlash of rods (see. Compare results of measurements to requirements of Specifications of the Head of engine, if necessary, replace the respective connecting rods.
- Finally, the connecting rod cap (lubricated bearing surfaces with oil), - track correctness of combination of landing labels and tighten bolts of their fastening with demanded effort.
| The threaded portion of bolts and nuts before tightening should also lubricate the clean motor oil. |
- Further installation is made in the reverse order of dismantle of components.
