Caution: Before removing the pistons and connecting rods, remove the cylinder head, oil pan and oil pump.
Dismantling
1. On 2.7L engines, remove the balance shaft (see subsection 3.3.14).
2. Use a reamer to remove the ridge formed by wear at the top of the cylinder.
3. Turn the engine over.
4. Check the axial play of the connecting rods by inserting feeler gauges between the crankshaft and the connecting rod. The axial play will be equal to the total thickness of the feeler gauges, at which the play disappears.
5. If the connecting rod axial clearance exceeds the standard value, the connecting rod(s) should be replaced. If new connecting rods are installed (or crankshaft), then the axial clearance may be less than normal (in this case, you need to grind the connecting rods, if necessary, consult a car service workshop). Repeat the procedure for the remaining connecting rods.
6. If there are no marks on the connecting rods and connecting rod caps (marking is indicated by an arrow) mark the corresponding cylinder number on them.
7. Loosen the cap nuts by turning them 1/2 turn at a time until the nuts can be turned by hand. Remove the cap from the connecting rod of the first cylinder together with the bearing shell; do not remove the bearing shell from the cap.
8. Push the piston with the connecting rod and the liner out through the top of the cylinder, having first put the sections of hoses on the bolts. If you feel resistance to the piston movement, check the cleanliness of the flange removal.
8. While turning the crankshaft, repeat the procedure for all other cylinders.
9. Assemble the connecting rods with the caps, tighten the cap nuts by hand.
