Connecting rods — removal and installation (Hyundai Accent LC)

Piston and connecting rod

Removal

Warning: Keep the connecting rod caps with the corresponding connecting rods for proper reinstallation into the engine cylinders.

1. Loosen the nuts and remove the connecting rod cap and the lower connecting rod bearing shell. To protect the crankshaft journals, place sections of rubber or plastic tube on the connecting rod cap mounting bolts.



2. Use a wooden block or a hammer handle to push the piston and connecting rod out of the cylinder.

Examination

1. When installing, make sure that the connecting rod and connecting rod cap match the cylinder number they are being installed in. When installing a new connecting rod, make sure that the marks that determine its position are on the same side as the marks on the other connecting rods.

2. Replace the connecting rod if there is damage on both bearing surfaces. Also replace the connecting rod if there is wear or damage on the surface mating with the piston pin.



3. Check the bend of each connecting rod. If necessary, replace the connecting rods. Replace the connecting rod together with the connecting rod cap.

• Allowable bending of connecting rod: 0.05 mm/ 100 mm length
• Permissible twisting of the connecting rod: 0.1 mm / 100 mm length

Installation

1. Install the spacer sleeve.



2. Install the upper side guide. To install the side guide, first place one end of the side guide between the piston ring groove wall and the spacer sleeve, press it down, then press it around the perimeter to install it into the piston groove.

Warning: Do not use pliers to spread the piston rings when installing the side guide.

3. Install the low side guide in the same manner.

4. Using piston ring pliers, install compression ring No.2.



5. Using piston ring pliers, install compression ring No.1.

6. Apply a thin layer of motor oil to the piston and piston rings.



7. Position the piston ring locks as shown in the figure.



8. Using a special tool, compress the piston rings onto the piston.

9. Place the piston with piston rings over the first cylinder, with the mark on the piston facing the front of the cylinder block.

10. Using a hammer handle, press the piston into the cylinder until the lower head of the connecting rod is seated on the crankshaft journal.

11. Install the connecting rod bearing into the connecting rod cap.



12. Install the connecting rod cover and secure with nuts.

Tightening torque: 32–35 Nm



13. Using a feeler gauge inserted between the connecting rod and the crankshaft, measure the connecting rod side clearance.

• Nominal connecting rod side clearance: 0.10–0.25 mm
• Maximum clearance: 0.40 mm
