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

Check of working gaps of radical bearings

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.

PERFORMANCE ORDER

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. The persistent inserts (washers) equipped with flanges have to be established in a bed of the fourth (including from a GRM drive belt) the radical bearing (see an accompanying illustration). 3. Wipe the surfaces of bearings in the block and radical necks of a bent shaft pure неворсящейся with rags. 4. 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. 5. Accurately lay carefully wiped bent shaft in radical bearings of the block. 6. Before finalizing a shaft, it is necessary to check sizes working gaps in its radical bearings. 7. 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 (see an accompanying illustration). 8. 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. 9a. In the order specified on an accompanying illustration in three stages tighten bolts of fastening of covers and/or their bridge with the required effort (Civic). 9b. In the order specified on an accompanying illustration in three stages tighten bolts of fastening of covers and/or their bridge with the required effort (Integra). Do not allow a shaft provorachivaniye in the course of tightening of fixture! 10. Turn out bolts and carefully uncover radical 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 some of covers does not give in to removal, accurately tap it for release by the hammer with soft brisk. 11. Determine the size of working gaps of bearings by width of the flattened-out threads measured on the scale applied on packing of the Plastigage set (see an accompanying illustration). Compare results of measurements to requirements of Specifications. 12. If the size of a gap goes beyond admissible limits, inserts not of that standard size were perhaps established (see 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 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 Check of a condition of a bent shaft). 13. 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

If the engine is equipped with the bridge of covers of radical bearings (B18C1, B18C5, D16Y5, D16Y7 or D16Y8), at first establish into place conrod and piston group (see Installation of conrod and piston assemblies and check of size of working gaps in conrod bearings of a bent shaft). Then bring all pistons into provisions of VMT that they did not prevent installation of the camshaft.

PERFORMANCE ORDER

1. Carefully take a bent shaft from the engine. 2. 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 the persistent surfaces of the fourth bearing also. Try not to allow hits of lubricant on backs of inserts! 3. 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. 4. Wipe and grease surfaces of inserts in covers. 5. Install on the engine of a cover of radical bearings and/or assembly of their bridge. 6. Screw fixing bolts. 7. In the required order, tighten bolts of fastening of covers of all bearings with the required effort. 8. Several times turn a bent shaft manually, checking freedom of its rotation. 9. 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 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 go beyond admissible limits. 10. Establish a new back epiploon of a bent shaft (see Replacement of a back epiploon of a bent shaft).
