GENERAL INFORMATION

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 V6 engines


PERFORMANCE ORDER
1. Arrange the block so that the lower part was turned up. 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 carefully enclose them in a bed of the block of cylinders. The corresponding response loose leaves enclose in covers, having combined ledges with samples. Loose leaves not to grease.
3. Establish persistent half rings (in the 3rd support on 4-cylinder engines and in the 2nd – on V6).
4. Establish the crankshaft and measure gaps in radical loose leaves. For this purpose put on a piece of a calibration wire on each radical neck of the crankshaft parallel to its axis.
5. Clear surfaces of loose leaves in covers, establish covers (a framework of covers on the engine 3VZ-FE) and tighten bolts in three steps with the set moment in the specified sequence (see fig. Sequence of a tightening of bolts of covers of radical bearings on 4-cylinder engines or fig. Sequence of a tightening of bolts of covers of radical bearings on V6 engines).
6. On V6 engines tighten bolts of covers on 90 °.
6. Unscrew bolts and carefully lift covers, compare thickness of each of crushed a provolok to a scale on packing and define gap size.
7. If the gap does not correspond to norm, the 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 of the crankshaft has a konusnost.
8. Remove from necks the remains of a wire and remove the crankshaft.
9. Grease radical necks and persistent surfaces of the crankshaft. To Smazhye necks under an epiploon molybdenic greasing also establish the crankshaft in the block of cylinders. Establish covers on former places so that shooters were turned towards a forward part of the engine. Establish half rings.
10. The top ring establish, having turned it on a crankshaft neck. Flutes of a ring 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 (see fig. Sequence of a tightening of bolts of covers of radical bearings on 4-cylinder engines or fig. Sequence of a tightening of bolts of covers of radical bearings on V6 engines).
13. Check freedom of rotation of the crankshaft.
14. Check axial люфт the crankshaft (see subsection 3.3.9.1).
15. Establish a back epiploon (see subsection 3.1.14 or subsection 3.2.15).
