PERFORMANCE ORDER
1. Take a bent shaft from the block of cylinders.
2. In the presence check that sprays of oil are installed in the block of cylinders.
3. Clear a back part of an insert and the place of its installation in the block of cylinders and covers of radical bearings. Establish inserts on the places.
4. Establish the top persistent half rings for adjustment of an axial side play of a bent shaft as follows:
– on 4-cylinder engines on the central radical bearing No. 3;
– on 5-cylinder engines on the radical bearing No. 4;
– on 6-cylinder engines on the radical bearing No. 5.
5. Oil a working surface of inserts pure engine and install a bent shaft in the block of cylinders of the engine.
6. Grease the lower inserts in covers of radical bearings with pure engine oil and check that ledges on inserts are in cover grooves.
7. According to marking establish covers of radical bearings on the places. Check that persistent half rings are on the corresponding cover of the radical bearing.
8. Grease bolts of fastening of covers of bearings of a bent shaft with pure engine oil, insert them into covers and tighten by hand. On 6-cylinder DOHC engines bolts of fastening of covers of radical bearings without carving openings under a bolt of a masloulavlivatel in a head are established from a driving chain. Before installation of bolts establish an arm of fastening of a maslozaborny tube.
9. Gradually and in the diagonal sequence from the center to edge tighten bolts of fastening of covers of bearings in several stages (see rice. Tightening of a bolt of fastening of a cover of the radical bearing the required moment, Tightening of a bolt of fastening of a cover of the radical bearing a dovorachivaniye on a certain corner).
10. Check that the bent shaft rotates smoothly and without jammings.
11. Establish a new sealing ring in a back cover of a bent shaft, then install a cover with new laying or on a thin layer of sealant on the block of cylinders (see rice. Drawing a thin layer of sealant on the interfaced surface of a back cover of a bent shaft on 6-cylinder petrol DOHC engines, Tightening of bolts of fastening of a back cover of a bent shaft on 6-cylinder DOHC engines).
12. Install pistons with rods.
13. Further assembly is made in the sequence, the return dismantling taking into account the next moments.
14. On 4-cylinder engines establish an asterisk of a bent shaft, a driving chain, a cover of a driving chain, the oil pallet and a flywheel / plate of the drive.
15. On 6-cylinder petrol SOHC engines establish an asterisk of a bent shaft, a driving chain, the lower cover of a driving chain, the oil pump, the oil pallet and a flywheel / plate of the drive.
16. On 6-cylinder petrol DOHC engines establish an asterisk of a bent shaft, a driving chain, the lower cover of a driving chain, the oil pump, a masloulavlivayushchy plate, the oil pallet and a flywheel / plate of the drive.
17. On diesel engines establish an asterisk of a bent shaft, a driving chain, a cover of a driving chain, the oil pump, a masloulavlivayushchy plate, the oil pallet and a flywheel / plate of the drive.
