Tighten the bolts and nuts in 2 stages in the sequence shown
Stage | Bolts/nuts | Torque |
1 | -1...8- | Screw in by hand until it stops. The bearing frame must be in contact with the cylinder head over the entire contact surface |
2 | -1...18- | 9 Nm |
Frame to right cylinder head - sequence and tightening torque
Tighten the bolts and nuts in 2 stages in the sequence shown.
Stage | Bolts/nuts | Torque |
1 | -1...17- | Screw in by hand until it stops. The bearing frame must be in contact with the cylinder head over the entire contact surface |
2 | -1...17- | 9 Nm |
The figure shows the cylinder head of the 2nd row of cylinders (left).
Valve mechanism
1. Valve: cannot be processed, only grinding is allowed; mark the mounting position for reinstallation; check; 2. Cylinder head: due to narrow tolerances, machining of valve seats is not allowed; 3. Valve stem seal; 4. Valve spring; 5. Valve spring retainer; 6. Valve retainer; 7. Camshaft lip seal: replace; 8. Bolt; 9. Nut; 10. Camshaft frame: with built-in camshaft bearings; 11. Intake camshaft: maximum runout: 0.01 mm; 12. Exhaust camshaft: maximum runout: 0.01 mm; 13. Roller arm: mark the mounting position for reinstallation; check the roller bearings for ease of rotation; Before installation, lubricate working surfaces; 14. Hydraulic compensator: mark the mounting position for reinstallation; check; Before installation, lubricate working surfaces; 15. Pressure limitation valve 1.0 bar: for lubrication points in the cylinder head; 25 Nm
