Installation of a bent shaft and check of working gaps of radical bearings

 PERFORMANCE ORDER

1. Installation of a bent shaft is the first step actually of assembly of the engine. It is meant that at this stage the bent shaft and the block of the engine are already properly cleaned, checked and restored.
2. Turn the engine upside down.
3. Give fixing bolts and uncover radical bearings and/or assembly of their bridge (4-cylinder engines).
4. If did not do it yet, take from the beds in the block and covers old inserts of radical bearings. Wipe beds pure неворсящейся with rags - they have to be perfectly pure.

Check of working gaps of radical bearings

 PERFORMANCE ORDER

Try not to touch surfaces of new inserts barehanded in order to avoid undesirable contact of bearings with always with the traces of oil and chemically aggressive substances which are present at fingers.

1. Wipe backs of new inserts of radical bearings and enclose equipped with an oil flute (if that is provided) halves in the beds in the block. Enclose the remained halves of inserts in the corresponding covers of bearings. Track that uvulas of inserts entered reciprocal landing grooves in beds of the block and covers. Oil openings in the block have also to correctly are combined with openings in inserts.

Do by no means attempts to begin to knock an insert resistant to installation in the bed the hammer. Grease with nothing bearings at this stage!

2. During the work on the V6 engine you remember that persistent inserts (washers) are established on the third bearing. On 4-cylinder engines the bearing No. 4 is persistent.
3. Wipe the surfaces of bearings in the block and radical necks of a bent shaft pure неворсящейся with rags. Check passability of oil openings of a shaft, in case of need clean them. Any foreign particles which are contained in maslotoka eventually inevitably get to bearings.
4. Accurately lay carefully wiped bent shaft in radical bearings of the block.
5. Before finalizing a shaft, it is necessary to check sizes of working gaps in its radical bearings.

6. Cut the calibrated plastic wire from the measuring Plastigage set pieces, length width of inserts are slightly shorter, and lay on one piece of a wire along each of radical necks of a shaft, parallel to their axis.

7. Wipe surfaces of inserts in covers and establish the last and/or assembly of their bridge on the regular place. Try not to shift the pieces of the calibrated wire laid along shaft necks. Slightly oil a carving of fixing bolts and screw them, having recorded covers.

8. In the order specified on one of accompanying illustrations in three stages tighten bolts of fastening of covers and/or their bridge with the required effort.

Do not allow a shaft provorachivaniye in the course of tightening of fixture!

9. Turn out bolts and carefully uncover radical bearings and/or assembly of their bridge. Put uncovered as an arrangement them on the engine. Try not to damage the flattened-out calibrated wire and do not turn a shaft. If any of covers does not give in to removal, accurately tap it for release by the hammer with soft brisk.

10. On width of the flattened-out threads, from measured on the scale applied on packing of the Plastigage set, determine the size of working gaps of bearings. Compare results of measurements to requirements of Specifications.

11. If the size of a gap goes beyond admissible limits, perhaps, inserts not of that standard size were established (see the Section Check of a State and Selection of Inserts of Radical and Conrod Bearings of a Bent Shaft). Before looking for new inserts, make sure that under enclosed at this stage dirt or oil did not get. If the calibrated wire is flattened out since one end more than from another, it demonstrates existence of conicity of a neck (see the Section Check of a Condition of a Bent Shaft).
12. Carefully remove the calibrated wire from necks, having scratched out all its traces some not too strong tool (for example, edge of an old credit card). As a last resort, it is possible to use own nail, - the main thing that on a surface of necks/inserts there is no scratch left and zadir.

Final installation of a bent shaft

 PERFORMANCE ORDER

1. Carefully take a bent shaft from the engine. Wipe the surfaces of bearings in the block and evenly grease them with a thin layer of molibdensoderzhashchy assembly motive lubricant. Do not forget to grease persistent washers also.

Try not to allow hits of lubricant on backs of inserts!

2. Make sure of absoluteness of purity of necks of a bent shaft, then grease (the same lubricant) the surfaces of pins contacting to epiploons and accurately lay a shaft in the block.
3. Wipe and grease surfaces of inserts in the block and covers.
4. Having deployed the block in bulk up, fill in it conrod and piston assemblies (see the Section Installation of Conrod and Piston Assemblies and Check of Size of Working Gaps in conrod bearings of a bent shaft).

ON 4-cylinder engines establish to the place of a cover of radical bearings and attract them bolts, without establishing still connecting bridge. Tighten fixture with effort about 14 ÷ of 27 Nanometers (if bolts are too long for pulling of one covers, enclose under their heads washers). Landing of covers will help to record a shaft on installation time of conrod and piston assemblies. Then covers should be dismantled again then to pass to implementation of the procedure of paragraph 5.

5. Install on the engine of a cover of radical bearings and assembly of their connecting bridge. Remember that the arrows cast on covers have to specify on the engine forward.

Do not forget to establish also persistent washers.

6. Slightly oil a carving part and the lower surfaces of heads of fixing bolts, then screw the last and tighten them by hand. Knock on end faces of pins of a shaft with the hammer through a brass or lead drift for the purpose of alignment of persistent washers and shrinkage of a shaft before final tightening of fixture. Tighten bolts of covers and the connecting bridge with the required effort.
7. Several times turn a bent shaft manually, checking freedom of its rotation.
8. In conclusion by means of the probe of lezviyny type or the DTI measuring instrument determine the size of an axial side play of a shaft (see the Section Removal of a Bent Shaft). If persistent surfaces of a shaft are not worn-out and are not damaged, and bearings are replaced on new, the axial side play should not exceed the limit of admissible range.
9. Establish a new back epiploon of a bent shaft and a priboltita to the block his holder (see the Section Installation of a Back Epiploon of a Bent Shaft).
