Assemble the piston cooling nozzle (650.1004118) with gasket (650.1004121).
Install the nozzle, screw on the screws (310107) and tighten Mcr = 20 ± 4 Nm (see Fig.1)
Install the upper crankshaft bearing shells, aligning the lubrication holes and lubricating the working surface with oil.
Install the upper thrust half rings with a slot to the cheek of the crankshaft (see Fig. 2).
Install the crankshaft, having previously lubricated the connecting rod and main journals with oil.
Install the crankshaft bearing shells into the lower main bearing caps and lubricate the work surface with oil.
Install the crankshaft main bearing caps with liners, following the numbering.
Install the middle cover together with the semi-rings with the convex part to the cheek of the crankshaft (see Fig. 2).
Fit the bolts and tighten to the recommended torque in the order shown in Fig. 3:
- - ensure the first tightening by 80 ± 8 Nm;
- - provide a second puff of 180˚ ± 6˚.
Check rotation.
Check the gap between the thrust half ring and the crankshaft web (see Fig. 4).
Adjust, if necessary, with half-rings of different thicknesses.
Be sure to replace those bolts whose length under the head exceeds 156 mm.
When reusing and reusing bolts, lubricate the threads with Loctite 518 sealant.
New bolts do not require lubrication, as they are already lubricated.
