Assembly of the cylinder-piston group (Chevrolet Aveo T250)

1. Connect the connecting rods to the pistons so that the mark on the piston is directed towards the front of the engine (towards the timing belt).

2. Install the piston pin installation tool guide.

3. Apply a layer of clean motor oil to the pistons.

4. Install the piston pins (see figure T250 2.075)



5. Measure the gap in the new piston ring joints by installing them in the cylinder without a piston.



6. Measure the side clearances between the rings and the walls of the piston grooves. Based on the measurement results, if the wear of the grooves is too great, replace the pistons.



7. Install the piston rings in the sequence shown in the figure using a ring expander.





8. Distribute the piston ring gaps as shown in the figure.



9. Apply a layer of engine oil to the cylinder walls.

10. Install the pistons into the cylinders using a ring crimper and lightly tapping with a wooden hammer handle.
