Cylinder Block Assembly
1 – cylinder block, 2 – oil pan, 3 – oil pan mounting bolt, 4 – oil drain plug, 5 – cylinder block access hole covers, 6 – bolt, 7 – access hole plug
Designations of cylinders on the engine cylinder block and pistons on their bottom
The diameters of the pistons and cylinders are divided into groups, which are designated by letters stamped on the engine cylinder block and the piston crown.
The cylinder and the piston interacting with it must belong to the same selection group.
Attention! New engine cylinder blocks have cylinders with diameters of groups "A" and "B" only.
Checking the piston protrusion above the upper plane of the cylinder block
1. Lubricate the piston surfaces and inner surfaces of the cylinders with oil.
2. Using a ring compressor, insert the piston-connecting rod assemblies into the corresponding cylinders.
Caution! The recess at the bottom of the piston must be directed towards the fuel pump.
3. Press the pistons deep into the cylinders.
4. Install the connecting rod bearings and connecting rod caps, tighten the nuts of the connecting rod cap bolts to a torque of 60 Nm.
5. Measure the moment of resistance when rotating the crankshaft using a torque wrench.
6. Lubricate the tappets with oil and insert them into the engine cylinder block guides in accordance with the markings.
7. Install the camshaft and intermediate plate together with a new gasket into the cylinder block. Install the timing drive (see subsection 3.5.7.2.5) and the timing chain cover together with a new gasket.
8. Lubricate the timing chain housing bolts with Frenetanch sealing paste and tighten them to a torque of 10 Nm.
9. Attach the oil pump to the cylinder block so that the conical hole in the pump body is located opposite the threaded hole.
10. Tighten the oil pump mounting bolt (with a conical end) to a torque of 22.5 Nm.
11. Install the copper washer and tighten the plugged hole nut to 30 Nm.
12. Install the original adjusting washer and carefully tighten the threaded plug.
13. Install the oil pan. Tighten the drain plug with a new gasket to 3 Nm.
