3.3.9.3. Installation and check of backlashes in radical bearings

THE GENERAL DATA

Sequence of a tightening of bolts of covers of radical bearings on 4-cylinder engines

Sequence of a tightening of bolts of covers of radical bearings on engines V6

PERFORMANCE ORDER

1. Arrange the block so that the bottom part has been turned upwards. Turn out bolts of covers, get covers and spread out them as their installation. Get from covers and the block of cylinders old loose leaves and absolutely wipe covers and beds. 2. Clear an external surface of new radical loose leaves with oil flutes, and cautiously enclose them in bed of the block of cylinders. Corresponding reciprocal loose leaves enclose in covers, having combined ledges with samples. Loose leaves not to grease. 3. Establish persistent half rings (in 3rd support on 4-cylinder engines and in 2nd – on V6). 4. Establish коленвал and measure backlashes in radical loose leaves. For this purpose put on a piece калибровочной a wire on each radical neck коленвала in parallel its axis. 5. Clear surfaces of loose leaves in covers, establish covers (a skeleton of covers on the engine 3VZ-FE) and tighten bolts in three steps with the set moment in the specified sequence (Sequence of a tightening of bolts of covers of radical bearings fig. see 4-cylinder engines or fig. Sequence of a tightening of bolts of covers of radical bearings on engines V6). 6. On engines V6 tighten bolts of covers on 90 °. 6. Turn away bolts and cautiously lift covers, compare a thickness of each of crushed проволок to a scale on packing and define backlash size. 7. If the backlash does not correspond to norm wrong selection of dimensional group of loose leaves can be the reason. Be convinced that at measurements between bearings and surfaces of covers there were no pollution or oil. If the width of the crushed wire on the ends strongly differs, the radical neck коленвала has конусность. 8. Remove from necks the rests of a wire and remove коленвал. 9. Grease radical necks and persistent surfaces коленвала. Смажье necks under an epiploon молибденовой greasing also establish коленвал in the block of cylinders. Establish covers on former places so that arrows have been turned towards a forward part of the engine. Establish half rings. 10. The top ring establish, having turned it on a neck коленвала. Ring flutes should be turned outside. 11. The bottom rings are inserted into a flute on a cover. 12. Tighten bolts in three steps with the set moment in the specified sequence (Sequence of a tightening of bolts of covers of radical bearings fig. see 4-cylinder engines or fig. Sequence of a tightening of bolts of covers of radical bearings on engines V6). 13. Check up rotation freedom коленвала. 14. Check up axial люфт коленвала (subsection 3.3.9.1 see). 15. Establish a back epiploon (subsection 3.1.14 or subsection 3.2.15 see).
