Removal

PERFORMANCE ORDER
1. In four-cylinder engines remove the balancing device of the engine.
2. By means of the special tool remove the 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, otherwise you damage the piston.
3. Turn the engine, a bent shaft up.
4. By means of probes measure a side gap of rods. If the gap exceeds admissible limits, the rod needs to be replaced. At emergence, any doubts, address experts.
5. If rods and covers of rods are not numbered, number them.
6. Weaken nuts of everyone of covers of a rod in stages on a turn floor. Twist nuts, and uncover the first rod and a bearing insert.
7. Remove an insert of the bearing and get a rod together with the piston. Not to injure a neck of conrod bearings, put on hose pieces bolts of rods.
8. Remove other rods and pistons similarly.
9. Put 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 piece 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, new pistons are not required to be installed.
6. Carefully examine all pistons on existence of cracks on a skirt of the piston and on a surface around a conrod finger.
7. Examine pistons on existence of scratches, zadir, the burned areas or corrosion.
8. If the skirt of the piston is strongly scratched, the overheat or abnormal combustion of fuel mix is the reason. In this case it is necessary to check carefully lubrication systems and coolings of the engine.
9. Existence of a hole in a head of the piston indicates abnormal combustion of fuel mix (there is its premature ignition). Leak from an inlet collector, bad fuel mix, the wrong installation of a corner of an advancing of ignition, malfunction in final system can be the reasons. Corrosion spots on the piston mean that cooling liquid proceeds in the combustion chamber.

10. Measure side gaps of piston rings. If the gap exceeds admissible limits, the piston needs to be replaced.
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 needs to be chiseled and installed 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 experts.
