Citroen Xantia

1. Carefully wipe backs of loose leaves and their bed in the bottom heads of rods and their covers.

2. Enclose loose leaves of bearings in the bottom heads of rods and their cover, having tracked hit of directing uvulas in reciprocal deepenings. Try not to touch working surfaces of loose leaves. If check of backlashes of old bearings is made, track, that loose leaves were established strictly on the former places. Check of working backlashes in шатунных bearings can be made two methods (see further).

3. The first method yields less exact results and demands приболчивания covers to the bottom heads undressed on necks of a shaft of rods (the subsection "Definitive installation of shatunno-piston groups", item 6 see more low). Loose leaves should be thus enclosed in the beds. Fix covers of the bottom heads of rods old nuts, having tightened them with demanded effort. Further, with the help нутромера or equipped нониусной the scale колумбуса makes measurement of internal diameters of the collected bearings. From received for each of assemblages of result then diameter of a corresponding neck of a cranked shaft is subtracted.
4. The second method means use of the calibrated plastic wire from measuring set Plastigage (Installation of a cranked shaft and check of working backlashes of radical bearings see).
5. Make sure of correctness of installation of loose leaves in beds of the bottom head of a rod and its cover. Wipe шатунные necks of a shaft pure неворсящейся rags. Lay along necks of cranks being in positions НМТ pieces of a plastic wire corresponding on length from a measuring set.
6. Put on necks rods, establish to the place of a cover шатунных bearings (be verified with landing marks).
7. Tighten nuts of their fastening with demanded effort (the subsection "Definitive installation of shatunno-piston groups", subitem 7-8 see more low). Try not to displace the pieces of the calibrated wire laid on necks of a shaft.
8. Without turning rods, remove covers and on degree of flattening of a wire define size of working backlashes of bearings. Measurement of a thickness of the flattened out wire is made on a scale put on packing to set Plastigage.
9. If the received results considerably differ from defined by specifications, whether it is necessary to check up the established loose leaves are correctly picked up for the size. Make sure also that between backs of loose leaves and beds of bearings extraneous particles have not got. Once again measure diameters шатунных necks of a cranked shaft. If the width of the flattened out piece of the calibrated wire from one of the ends is more than with opposite, it is necessary to check up a corresponding neck of a shaft on presence excessive конусности. In case of need replace the loose leaf or give a shaft in проточку with a selection of new loose leaves of the repair size.
10. It is necessary to notice that manufacturers of cars (company Citroyon) does not stipulate an admissible range of sizes of working backlashes in шатунных bearings. The values resulted in Specifications are taken as usual for engines of considered type and they should be considered only as rough. The detailed information on sizes of working backlashes and selection of loose leaves шатунных bearings always can be received on firm car repair shops of company Citroyon.
11. In summary cautiously scratch out traces of the flattened out wire from necks of a shaft a nail or edge of an old credit card.

1. Sleeves of cylinders (at a corresponding complete set) should be established on the places (Cleaning and check of a condition of the block of cylinders/kartera of the engine see). Laid in the block of cylinders the cranked shaft should be fixed covers of radical bearings (Installation of a cranked shaft and check of working backlashes of radical bearings see).
2. Check up correctness of landing of loose leaves of bearings in the beds (see above). If new loose leaves are established, track, that from them traces of preserving greasing have been completely removed. Take advantage for rubbing of loose leaves by kerosene or other suitable solvent. Dry wipe pure loose leaves неворсящейся rags. The same rags wipe rods.
3. Grease mirrors of cylinders, pistons and piston rings with pure impellent oil. Spread out shatunno-piston assemblages as their installation on the engine on a pure working surface. In a case if covers fasten on heads nuts, wind hairpins with an adhesive tape for the purpose of protection of cylinders and necks of a cranked shaft.
4. Begin with installation of shatunno-piston assemblage of the first cylinder. Make sure that locks of piston rings are developed the friend in relation to the friend under correct corners (Installation of piston rings see). Press out rings оправкой the special tool.

5. At the top enter an assemblage rod into the first cylinder of the engine. Take care of casually not to scratch a cylinder mirror. On petrol engines track, that the label in the form of an arrow on the piston bottom has appeared is directed towards an arrangement of drive ГРМ, on diesel engines track, that cut in the piston bottom in shape трилистника has appeared will develop forward on the block (towards installation of the oil filter). Упершись the wooden handle of a hammer in the piston bottom, push its skirt in the cylinder, densely having pressed to a block surface pressing out rings оправку the tool. Continuing to press densely оправку, push the piston more deeply while its bottom will not appear заподлицо with a surface of the block of cylinders interfaced to a head.

6. Make sure of correctness of installation in the beds of loose leaves шатунного the bearing. Plentifully grease a neck of the first crank of a cranked shaft and both loose leaves with pure engine oil. Watching to damaging a cylinder mirror, accurately put on the bottom head of a rod the neck of a shaft resulted in position НМТ.
7. Establish a cover шатунного the bearing, then screw fixing nuts and tighten them by hand. Track, that identification labels have appeared in the correct image are combined (directing uvulas of loose leaves should rest each other).

8. In regular intervals, in stages tighten fixing nuts with effort of the first stage of a tightening.

1. Completely ослабьте both nuts and again tighten, this time with effort of the second stage. Now hold on nuts on a corner of thirds of stage of a tightening, - take advantage of a goniometer, or the template cut out from a cardboard.

1. Hold on nuts on a corner of the second stage.

1. Having finished a tightening of nuts of fastening of a cover of a rod, check up freedom of rotation of a cranked shaft (the shaft can rotate a little hardly, however should not take place jerks and закусываний).
2. Operating in a similar manner, establish on the engine the remained shatunno-piston assemblages.
3. Establish a head of cylinders and the oil pump (the Repair procedures which are not demanding extraction of the engine from the car - petrol engines or the Repair procedures which are not demanding extraction of the engine from the car - diesel engines see).
