Attention:
- Thoroughly clean all parts prepared for assembly.
- Before installing parts, lubricate their working surfaces with fresh engine oil.
- Install new gaskets and seals.
1. Install the main bearing shells in the cylinder block (top liners) and in main bearing caps (bottom liners).
Attention: Insert the liners with the oil hole into the block.
2. Install the upper thrust washers at the #3 main bearing with the oil grooves facing out.
3. Put the crankshaft in the cylinder block.
4. Install the main bearing caps and lower thrust washers.
Attention: each cover is numbered.
A) Install the thrust washers at the No. 3 main bearing cap with the oil grooves facing out.
b) Install the covers, orienting them correctly.
V) Apply a light coat of engine oil to the threads and bolt heads of the covers.
G) Install and evenly tighten the ten main bearing cap bolts in several passes in the sequence shown.
- Tightening torque - 78 Nm
d) Check crankshaft rotation.
e) Check crankshaft end play.
5. Install the connecting rod and piston group.
A) Place short hoses over the protruding threads of the connecting rod bolts to prevent damage to the cylinder liners and crankshaft journals.
b) Using a piston ring crimper, install the piston kits oriented with the marks "before" in the right direction.
6. Install the connecting rod bearing caps.
A) Pick up the caps for the connecting rods.
b) Position the connecting rod caps with the marks forward.
V) Apply a coat of engine oil to the threads and under the nuts of the connecting rod bolts.
G) Install and sequentially tighten the nuts of the connecting rod bolts in several passes.
- Tightening torque - 49 Nm
d) Check the ease of turning the crankshaft.
e) Check up size of an axial backlash of the bottom heads of rods.
7. Establish the holder of a back epiploon of a cranked shaft.
- Tightening torque - 12 Nm
8. Install the timing chain housing.
Install a new gasket and secure the timing chain housing with nine bolts and one nut.
- Tightening torque - 18 Nm
9. Install a new gasket and secure the coolant bypass tube.
10. Install the coolant drain cock after lubricating it with sealant.
