Cleaning and check of a condition of the block of cylinders/kartera of the engine



1. Remove from the block all hinged units and components, and also electric gauges and switches. For the fullest cleaning it is necessary to take выжимные stoppers, drill in stoppers small apertures, screw in them саморезы and, seized flat-nose pliers for heads of screws, pull out stoppers from the block.

2. On models with the aluminium block take sleeves of cylinders (the subsection "the Aluminium block with“ wet "sleeves", item 1 see more low).
3. At a corresponding complete set turn out a fixing bolt and take from the block a distributing tube маслораспылителей coolings of pistons.
4. Scratch out all traces of a material of an old lining from interfaced surfaces of the block, and at a corresponding complete set, also from moulding of covers of radical bearings. Try not to damage prokladochnye / sealing surfaces.
5. Take all заглушки oil galleries (where they are provided). Заглушки are planted very hardly and, probably, will demand drilling with the subsequent restoration of a carving by a tap. At assemblage of the engine replacement заглушек is made without fail.
6. If картер it is strongly polluted, performance of steam cleaning is required.
7. After return of the block from cleaning it is necessary to clean again all oil apertures and galleries. Wash out all internal channels of the block warm water. Continue washing until pure water will not start to follow from apertures. Carefully dry the block, then slightly oil its interfaced surfaces and mirrors of cylinders in order to avoid corrosion development. If there is an access to a source of compressed air, take advantage of it for acceleration of process of drying and a purge of apertures, channels and galleries.

At use of compressed air put on goggles!

8. If картер the engine it is polluted not too strongly, will enough wash out its hot soap water with application of a rigid brush. It is not necessary to try to save time for block washing - concern to this procedure with all responsibility. Without dependence from the chosen method of cleaning, as a result of its all oil apertures and channels should appear absolutely pure, and the block - carefully dried up. In order to avoid corrosion development slightly oil mirrors of cylinders.

9. All carving apertures in the block are necessary for "banishing" a tap approaching on the size, carefully having removed from coils of a carving corrosion products, old hermetic and other adjournment. Besides, such "prorace" will help to restore the damaged carving. Whenever possible, blow apertures the compressed air, having removed from them a shaving and dust.

All traces of greasing and solvent should be completely removed from deaf apertures in order to avoid destruction of moulding of the block by hydraulic pressure at a tightening of bolts.

10. Grease with suitable hermetic new заглушки oil galleries and screw them in the apertures in the block. Strongly tighten заглушки.
11. At a corresponding complete set establish to the place of a nozzle маслораспылителей coolings of pistons. Fix distributing tube of sprays bolts, having tightened the last with demanded effort.
12. If be not going to start immediately engine assemblage, wrap the block in a pure polyethylene package. Do not forget to take care also of protection of interfaced surfaces and mirrors of cylinders against corrosion (see above).

Condition check

The pig-iron block


1. Visually check up block moulding on presence of cracks and corrosion traces. Check up, whether the carving in any of fixing apertures is broken. If there were suspicions on internal leaks of a cooling liquid, probably, it makes sense to address to experts of car-care centre, having asked them to execute careful check of a condition of the block with application of the special equipment. In case of need make regenerative repair or replace the block.
2. Check up mirrors of cylinders on presence of scratches and задиров. At detection of such defects it is necessary to check up a condition of corresponding pistons. In considerable deterioration of cylinders specifies presence of appreciable step deterioration in their top part.
3. It is necessary to make measurement of their diameters for more exact estimation of degree of deterioration of cylinders in several points. Enter нутромер into the first cylinder and make measurement of its diameter in three various sections in parallel an axis of a cranked shaft. One measurement is made in the top part of the cylinder, the second is direct under edge of a fillet of the step deterioration, - in the central part of the cylinder and the third - on distance about 10 mm over the bottom cut. All measurements are made in a plane, a perpendicular axis of cylinders and in parallel an axis of a cranked shaft.
4. Repeat measurements in former sections of cylinders, this time perpendicularly axes of a shaft. Compare results of measurements to requirements of Specifications (in the absence of the standard data, address for consultation to experts of the firm service-centre of company Citroyon).
5. If any of results falls outside the limits an admissible range, cylinders are subject проточке with the subsequent replacement of pistons on new, the corresponding repair size. Unique alternative проточке cylinders is full replacement of the block complete with pistons.

The aluminium block with "wet" sleeves


1. Where it is required, remove clamps of sleeves, then with the help выколотки from a firm tree beat out sleeves from the block. Having liberated sleeves from cylinders, turn the block sideways and take sleeves from cylinders manually. In process of extraction of sleeves, paste on their left walls (from outside transmissions) adhesive tape strips on which at once inscribe number of the corresponding cylinder, considering as the first the nearest to a flywheel/privodnomu to a disk.

2. Remove from the bases of sleeves sealing rings.

3. Check up sleeves on presence of deep scratches and задиров, their mirrors specifying in excessive deterioration.
4. At presence near at hand the measuring equipment, measure internal diameter of a sleeve of the first cylinder in three sections in parallel an axis of a cranked shaft (the subsection "Pig-iron block", item 3 see above).
5. Repeat measurements in the same sections, but perpendicularly axes of a shaft. Compare results to requirements of Specifications.
6. Operating in a similar manner, estimate degree of deterioration of the remained sleeves.
7. In case of deterioration of sleeves over an admissible limit, or in the presence of deep defects of their mirrors, it is necessary to get the replaceable complete set. In the absence of confidence of an estimation of a condition of sleeves do not hesitate to address for the help to experts.
8. Replacement of sleeves of cylinders is made complete with pistons and piston rings. Sweep up that acquisition of sleeves in an individual order is not obviously possible.
9. For the purpose of preservation of factory admissions complete sets of replaceable pistons and sleeves are divided into three dimensional groups. Identification of dimensional group of the piston is made by means of warranty marks (And, In or) which is put on their bottoms. Sleeves are marked by risks (from one to three) which are put on from the top sponges. Sleeves with one риской it is used complete with pistons of group And, with two - In and with three, accordingly, - S.Dopuskaetsja installation in various cylinders of pistons and sleeves of different groups, however in each cylinder the sleeve without fail should correspond on group to the piston.
10. Before installation of sleeves carefully wipe surfaces of the block of cylinders interfaced to them. By means of a fine-grained emery paper заполируйте agnails and the teases, capable to lead to damage of new sealing rings. Dry wipe sleeves, then establish on their bases new sealing rings, preliminary slightly having greased the last.
11. At installation to the place of old sleeves watch that they have been planted strictly in former cylinders and were in the correct image сориентированы in the block (on the pasted strips of an adhesive tape). Try at refuelling of sleeves in cylinders not to damage sealing rings. Definitively sleeves застукиваются in the block a hammer through выколотку from a firm tree. Blows should be lungs and be put until a sleeve will not rest the landing coat hanger. Carefully wipe acting surfaces of sleeves and slightly oil them in order to avoid corrosion development.
12. Having finished installation of sleeves, check up their size выступания from the block with the help циферблатного a measuring instrument плунжерного type (it is alternatively possible to take advantage of a measuring instrument of planeness and probeом лезвийного type). Compare results of measurements to requirements of Specifications. The maximum difference of size выступания between any two sleeves should not exceed the stipulated admissible value.
13. At installation of new sleeves their shift from the cylinder in the cylinder for the purpose of reduction in norm of control value (on a difference of sizes выступания) is supposed. Remember that the piston should be rearranged together with a sleeve.
14. If to achieve satisfactory result it is not possible, address for the help to experts of car-care centre.
