Citroën Xantia

1. On models of early years of release pick up a set of new top inserts, then a set of new lower inserts with blue marking (see above) if such opportunity exists. On later models where the modified radical bearings are already installed, check of gaps in them can be checked with old inserts though the result cannot be considered more exhaustively exact (better also to take a new set).
2. Wipe backs of the picked-up inserts and their bed in the block of cylinders and covers of bearings.
3. Enclose inserts in the beds, having tracked that their uvulas entered gearing with reciprocal grooves in a body of blocks/covers. When checking old inserts track that they were established strictly on the former places. Try not to touch working surfaces of inserts. Pay attention that the flute is provided in working surfaces of the top inserts, - do not mix them with smooth lower.
4. Check of size of a working gap of bearings is made by one of the methods described below.
5. The first method more difficult in view of need of application of a micrometer and нутромера / Columbus, demands installation of covers of radical bearings (with the enclosed inserts) on the block. Tighten bolts of fastening of covers with the required effort (during check of gaps of bearings old bolts are used), then нутромером / Columbus measure the internal diameter of each of bearings. Now it is necessary to subtract diameters of the corresponding radical necks of a bent shaft from the received results, - the received results will show values of working gaps in bearings. Compare results of calculations to requirements of Specifications.
6. The second method (simpler and exact) means use of the special measuring Plastigage set (Citroyon No. OUT 30 4133 T). The size of a gap is determined by extent of flattening of pieces of the soft calibrated wire from set at its tightening between inserts of covers of radical bearings and necks of a shaft. Measurement of width of the flattened-out pieces of a wire is performed on the scale applied on set packing.
7. Enclose the top inserts of radical bearings in the beds in the block of cylinders, then carefully lay a bent shaft in the block. Do not use any lubricant! Necks of a shaft have to be absolutely pure and dry.
8. Cut five pieces of a wire, on length is slightly shorter than radical necks of a bent shaft and lay them along necks, parallel to an axis of the last.
9. Wipe working surfaces of the lower inserts in covers of bearings and grease them with a thin layer of a silicone compound for the purpose of prevention of sticking to them the calibrated wire. Install covers on the regular places in the engine (be verified with factory marking). Screw old fixing bolts and, watching to breaking integrity of the flattened-out wire pieces, tighten them with the required effort (see below in this section). Do not allow a provorachivaniye of a bent shaft after laying on it the calibrated wire.
10. Uncover, - again try not to destroy the flattened-out wire and not to turn a shaft.
11. On the scale applied on packing of the Plastigage set determine the size of a working gap of bearings by extent of flattening of the calibrated wire, you remember that on packing two scales can be put (inch and metric), - do not mix them. Compare results of measurements to requirements of Specifications.
12. If gap size significantly differs from demanded, check whether dirt or other foreign particles got under an insert back. Wipe backs of inserts and their bed and repeat check. At repeated negative result check compliance of inserts to diameters of necks of a bent shaft. If the calibrated wire is flattened out since one end inadmissibly it is more, than from another, the neck has conicity and is subject to a pro-point.
13. If results of measurements significantly differ from stipulated in Specifications, use the obtained data, and also data on thickness of inserts (see above) for definition of the required dimensional group of new inserts. Remember that it is always better to install working gaps in bearings closer to the lower bound of admissible range adjusted for wear.
14. If necessary pick up new inserts from other dimensional group and repeat check of working zazhor in bearings.
15. In conclusion, having made sure of compliance of sizes of a working gap of bearings to standard requirements, remove traces of the flattened-out wire from shaft necks, having carefully scratched out them a nail or edge of an old credit card.

1. Accurately take a bent shaft from an engine case.

2. By means of couple of dabs of dense lubricant record the top half of persistent washers on both sides of a bed of the second radical bearing in the block of cylinders, - both washers have to be established by flutes of maslotok outside.

3. Enclose inserts of radical bearings in the beds in the block of cylinders and covers. At installation of new inserts track that from their surfaces the preserving lubricant was completely removed, - wash out inserts kerosene, then carefully wipe pure неворсящейся with rags. Plentifully grease inserts in an engine case with pure engine oil of the required grade.

4. Lay a bent shaft in the block of cylinders so that necks of the second and third cranks appeared in provisions of VMT, and the first and fourth, respectively, - NMT. According to instructions of the section Check of a Condition of a Bent Shaft, measure the size of its axial side play.

5. Oil motive the lower inserts in covers of bearings. Make sure of correctness of landing of uvulas of inserts in reciprocal deepenings in covers.

6. Establish covers of the second and fifth bearings on the regular places (deepenings under uvulas of inserts in beds of the block and covers have to appear on the one hand. Start fixture (nuts/bolts) and freely tighten it.

7. Grease with sealant the surface of the block interfaced to a cover of the 1st radical bearing, around openings under installation of sealing strips.

8. Get uvulas of sealing strips on pins in the basis of a cover of the first bearing and put strips in the flutes in a cover. Now it is necessary to prepare two thin metal plates (thickness less than 0.25 mm) for the purpose of fixing of sealing strips at installation of a cover.

9. The Citroyon company releases the special adaptation working like a clamp for this purpose, however, also couple of edges of the old measuring probe perfectly will approach (track that from their edges all agnails and teases capable to damage rubber of sealants were removed previously.

10. Oil the motive both parties of metal plates (if you use plates) and establish them on sealing strips. Install a cover of the first radical bearing on the engine and freely screw fixing bolts.

11. By means of flat-nose pliers take plates. Pull plates strictly horizontally.

12. Evenly tighten fixture of covers of radical bearings with the required effort, then a sharp knife cut protruding edges sealing covers of the first bearing so that they acted over the interfaced surface of the block approximately on 1 mm.

13. On models 1580 and 1761 of cm ³ screw side bolts of fastening of the central radical bearing, - one in a forward part of the block and one in back, - do not forget about sealing washers. Tighten both bolts with the required effort.
14. Establish a back epiploon of a bent shaft (see. The repair procedures which are not demanding extraction of the engine from the car - the petrol engines or Repair procedures which are not demanding extraction of the engine from the car - diesel engines).
15. Install on the places conrod and piston assemblies (see Installation of conrod and piston groups on the engine and check of working gaps of conrod bearings).
16. Establish a segment spline in a groove of pins of a bent shaft, then put on a pin the leading asterisk of the oil pump with the remote plug (if that is provided). Throw with a driving chain an asterisk.
17. Dry wipe the interfaced surfaces of the holder of a forward epiploon of a bent shaft and the block of cylinders. Measure depth of landing of an epiploon, then take it from the nest by means of the screw-driver with a flat sting.
18. Grease with suitable sealant the interfaced holder's surface. Make sure available on the places of the directing pins and put the holder on a pin of a bent shaft, having densely pressed it to the block. Tighten boats of fastening of the holder with the required effort.
19. Working according to the instructions stated in sections the Repair procedures which are not demanding extraction of the engine from the car - the petrol engines or Repair procedures which are not demanding extraction of the engine from the car - diesel engines, establish a new forward epiploon of a bent shaft.
20. Make sure of correctness of landing on asterisks of a driving chain of the oil pump, then install the oil pump and the pallet of a case (see. The repair procedures which are not demanding extraction of the engine from the car - the petrol engines or Repair procedures which are not demanding extraction of the engine from the car - diesel engines).
21. If removed, establish into place a head of cylinders (see. The repair procedures which are not demanding extraction of the engine from the car - the petrol engines or Repair procedures which are not demanding extraction of the engine from the car - diesel engines).
