Removal

PERFORMANCE ORDER
1. In four-cylinder engines remove the balancing device of the engine.
2. By means of the special tool remove a ledge in the top part of the cylinder, formed as a result of wear and deposits of products of combustion. Do not try to get the piston, without having removed a ledge, differently you damage the piston.
3. Overturn the engine, cranked shaft up.
4. With the help щупов measure a lateral gap of rods. If the gap exceeds admissible limits, it is necessary to replace a rod. At the emergence, any doubts, address to experts.
5. If rods and covers of rods are not numbered, number them.
6. Weaken nuts of everyone of rod covers in stages on a turn floor. Braid nuts, and uncover the first rod and the bearing loose leaf.
7. Remove the loose leaf of the bearing and get a rod together with the piston. Not to injure a neck of shatunny bearings, put on bolts of rods hose pieces.
8. Remove other rods and pistons similarly.
9. Combine elements of each of pistons separately not to mix them.

Check

PERFORMANCE ORDER
1. Remove piston rings by means of the tool for installation of piston rings, try not to scratch the piston.
2. By means of a wire brush or a small emery paper clean a piston head from deposits.

3. By means of the special tool or a slice of the broken piston ring clean flutes of piston rings.
4. After removal of all deposits, clear pistons and rods solvent and dry up them.
5. If pistons and walls of the cylinder are worn-out not strongly and cylinders were not chiseled, it is not required to establish new pistons.
6. Carefully examine all pistons on existence of cracks on a skirt of the piston and on a surface round a shatunny finger.
7. Examine pistons on existence of scratches, задиров, the scorched areas or corrosion.
8. If the skirt of the piston is strongly scratched, the reason is the overheat or abnormal combustion of a fuel mix. In this case it is necessary to check carefully systems of greasing and engine cooling.
9. Hole existence in a head of the piston indicates abnormal combustion of a fuel mix (there is its premature ignition). The bad fuel mix, the wrong installation of a corner of an advancing of ignition, malfunction in final system can be the reasons leak from an inlet collector. Corrosion spots on the piston mean that cooling liquid proceeds in the combustion chamber.

10. Measure lateral gaps of piston rings. If the gap exceeds admissible limits, it is necessary to replace the piston.
11. Measure a gap between the piston and the cylinder, for this purpose measure diameter of the piston perpendicular to a piston finger and measure diameter of the cylinder. Take away diameter of the piston from diameter of the cylinder. If the gap exceeds admissible limits, the cylinder it is necessary to chisel and establish the new piston and new piston rings.
12. Check a gap between the piston and a rod.
13. Examine rods on existence of cracks and other damages. For more detailed checking of pistons and rods address to experts.
