1. Insert the bearings into the cylinder block and connecting rods.
2. Install the crankshaft so that the connecting rod journals for cylinders No. 2 and No. 3 are directed straight down.
3. Insert the crankshaft into the block by installing the crankpins into the No. 2 and No. 3 connecting rods, install the connecting rod caps and nuts, and tighten by hand.
4. Rotate the crankshaft clockwise to install the journals into the No. 1 and No. 4 connecting rods, install the connecting rod caps and nuts, and tighten by hand.
Note. Install the covers so that the recess of the cover liner is directed in the same direction as the recess on the connecting rod.
5. Check the connecting rod bearing clearance with measuring plates, then tighten the nut.
Tightening torque:
Engines А16А2, В16А4, В16А5, В16А6: 40 Nm
Apply engine oil to the threaded parts of the bolts.
Other engines: 31 Nm
Apply engine oil to threaded parts.
Note: The numbers on the connecting rod are used to determine the size of the larger connecting rod bore and do not indicate the position of the piston in the engine.
6. Install thrust washers on journal No. 4. Lubricate the surfaces of the thrust washer.
7. Install the main bearing caps. Check the clearance with a bearing clearance tool, then tighten the bearing cap bolts in 2 stages.
First stage: 25 Nm
Second phase:
- engines V16A2, V16A4, V16A5, V16A6: 76 Nm
- engines D16Y4, D16Y5, D16Y6, D16Y7, D16Y8, D16Y9/D1626: 51 Nm
- engines D14A3, D14A4, D1524a D15Z5, D15Z6, D15Z7, D13B2, D15B2, D15Z1: 44 Nm
Attention. Coat the surfaces of the thrust half-rings and bolt threads with oil.
Warning. Whenever the crankshaft or connecting rod bearing requires replacement, it is necessary to run the engine at idle speed after assembly until it reaches normal operating temperature.
Attention:
- Use Liquid Gasket Part No. OY740-99986 or 08C70-XD134S.
- Make sure contact surfaces are clean and dry before applying liquid gasket.
- Apply the liquid gasket evenly and carefully to cover the entire contact surface.
- To prevent oil leakage, apply liquid gasket to the internal threads of the bolt holes. Install the parts within five minutes after applying the liquid gasket. Instead, reapply the liquid liner after removing the old one.
- After assembly, wait at least 20 minutes before filling the engine with oil.
8. Apply liquid gasket to the contact surface of the right side cover block, then install it on the cylinder block.
9. Apply liquid gasket to the contact surface of the oil pump and block, then install the oil pump to the cylinder block. Apply lubricant to the oil seal lugs. Then, install the oil pump while aligning the inner rotor with the crankshaft. After installing the pump, remove excess grease to prevent damage to the seal.
Attention:
- Apply a light coat of oil to the crankshaft and oil seal boss.
- Using new O-rings, apply oil to them during installation.
