Place the dry main bearing shells in the engine housing. Install the thrust washers so that their grooves are visible.
Lubricate the main bearing shells with engine oil and place the crankshaft on them.
Place the main bearing caps with the half shells.
Tighten the main bearing cap bolts to the specified torque values.
Checking the ease of rotation of the crankshaft in the bearings. If you find any difficulties, you must loosen the bearing caps one by one to find the cap that caused the defect.
Defects usually include:
- poorly selected bearing clearance
- contamination of the interacting surfaces of the engine housing liners or bearing cap
- in damage to parts
Install the pistons with connecting rods. The arrow placed on the piston bottom should point toward the front of the engine (i.e. toward the installed toothed belt or chain). Install the piston ring clamp on the piston to compress the piston rings. Make sure that the piston rings are fully seated in the piston grooves.
Insert the pistons with connecting rods into the cylinders and lightly tap the bottom of the hammer with the handle to insert them into the cylinders (Fig. 2.29). Before you begin inserting the piston into the cylinder, you must check each time whether the piston rings have entered the grooves and whether the belt clamp is installed correctly on the piston.
Lubricate the connecting rod bearings in the lower connecting rod heads with oil and put on the oiled caps with liners. Screw in the connecting rod bolts and tighten them to the recommended torques. Check whether the connecting rods rotate freely on the crankshaft journals. During the check, rotate the shaft in both directions.
Screw in the oil pressure sensor.
Install the front engine cover (in a diesel engine, the timing cover) with the oil pump. Pour some engine oil into the pump and turn the pump shaft several times to lubricate the inside of the pump. Before installation, install the front crankshaft oil seal in the cover.
Install the rear crankshaft cover. It must be installed properly relative to the sealing surface of the oil pan.
Install the flywheel and tighten the bolts to the specified torque. Use new bolts during assembly, after lubricating their threads with a sealant.
Install the clutch using the centering rod. Tighten the bolts in several stages to avoid distorting the clutch housing. The clutch centering rod should be easy to remove. If you have difficulty removing the centering rod, you will need to center the clutch slave disk again. The old primary shaft of the gearbox can be used instead of the centering rod. Further steps for installing the engine will be presented separately for each engine type.
