Piston rings, how to replace the piston rings with their own hands

If the machine serves a long time, the owner does not plan to change it - in the end, the replacement time of the piston rings will come. This procedure depends not only on the car run, the practice shows that the wear of the piston rings, mainly depends on the quality of the oil, which is poured into the engine and from the period of its replacement.

Piston rings, symptoms pointing to wear piston rings

The very first, main symptom, which is suspected of wear of piston rings - increase the fuel consumption by car.

Reducing the compression of the engine - indicates the wear of the piston rings. The driver is trying to add power to the engine and puts it harder on the gas pedal.

Because of such actions, extra gasoline can get into the crankcase, pour candles, as a result, the engine troit and increases fuel consumption.

Experienced drivers immediately pay attention to the reduction of engine power and only one of this feature, come to the conclusion to replace the piston rings.

The power of the machine, directly depends on the state of the piston rings and if the piston rings are not capable of creating the desired compression, the engine will not give the desired power.

Normally, compression should be 9.

When the engine is reduced, the oil consumption increases, the oil surplus can fall into the combustion chamber.

I did not have time to burn, the oil enters the catalyst and flies through the exhaust pipe.

If you see a gray smile from the muffler in front of the riding car, most likely, the piston rings were worn.

Piston rings, what functions they perform

The task of piston rings includes simultaneous execution of several actions:

-Grequent work of the piston rings is able to create complete sealing of the combustion chamber and will not allow the penetration of gases to the Carter;

-pall rings should protect the piston itself from overheating, since the piston head constantly concentrates heat, and the piston rings are able to direct it heat to the cylinder, which is washed by coolant;

-Evilly working piston rings are able to distribute the oil film over the surface of the cylinder and prevent oil from entering the combustion chamber.

Uniform fitting of piston rings to the entire surface of the cylinder - it is a good work of piston rings.

But over time, as a result of loads, the cylinder is capable of changing its shape, it leads to an increase in the gaps in the channels, the elasticity of the piston rings is disrupted.

The totality above these factors leads to a disruption of sealing, to the appearance of gases in the crankcase, to the wear of the entire piston group.

To bring the engine to the desired order, it is necessary to replace the piston rings.

This operation is not so complicated, to replace the rings to new, can one person, without special professional knowledge.

Basically, even the engine does not need to shoot, only certain tools are needed.

First you need to decide, remove the engine or not. Eyes examine cylinders and estimate their condition.

If you are not sure about your abilities, invite a specialist, it will determine, you need a dismantling of the engine or not.

If "flew" only piston rings, in which case, the engine is not needed.

The engine must be removed only if there is a boring of cylinders or overhaul.

We warn you that you simply remove the head of the cylinders, but it is difficult to collect and put in place. Therefore, all the same, invite a specialist.

Piston rings, replacement of piston rings with their own hands

Before you start work, prepare the tools:

-a set of keys;

- Heads with a rattling;

-inimometric key;

-What for rings;

-Furnish hexagons;

-Net quality set of piston rings.

By purchasing piston rings, carefully inspect the packaging and the rings themselves, pay attention to the label - it shows the top and bottom of the rings.

And now proceed directly to work:

-tifint the palter of the crankcase, pre-drained the oil;

- show the oil pump and check it on wear;

- Connect the terminal plus with the battery;

-tosol merge;

- 4 nuts, remove the decorative engine lining;

-Product dismantling of the intake manifold, the work is done in the following order. First, we display the throttle drive cable, disconnect the throttle assembly, remove the ignition coil and all wires. From the top of the collector, we remove all hoses, weakening all the clamps that connect the upper nozzles with the bottom.

If you doubt that you can collect everything in the reverse order - before dismantling, take a picture of the nodes, and the photo will tell you how to assemble correctly;

- Hanging bolts and disconnecting all hoses, remove the valve cover;

-Not off all attachments from the engine;

-Prip dismantling of all fuel hoses;

-To contact the fan switching on the fan sensor;

- Cut the thermostat fixation bolts, slide all hoses to the side, and if the design does not allow you to move the hoses, disconnect them;

-Dontent generator roller and timing belt cover;

- Withdraw the timing belt cover, unscrew the belt tension roller, remove the belt itself and dismantle the camshaft pulleys. Be careful, do not lose the swords. To the camshaft do not scroll, fix it with a thin montage, remove the second part of the plastic casing;

- Demonstrate the casing from the exhaust manifold and remove the collector itself;

- Advance all connectors from all engine sensors;

- cover the entire harness of wires going on the nozzles, entirely;

-Click the head of the cylinder block;

- Searel under the car, unscrew the bolts on the oil fear and remove it, slightly shaking;

- Suppose the desired piston at the bottom of the dead point, for this, turn the crankshaft;

- cover the connecting rod and push the pistons of cylinders to the top;

-ake the pistons from Nagara;

- Love old rings and put new, do not forget to first put the oil-chain ring. Rings at the end are necessarily tightened by a special mandrel;

- Play the assembly in the reverse order. Nominal clearance when installing rings - 0.25-0.45 mm.

Do not forget to lubricate piston rings and all the details of the oil.

By replacing the piston rings, make an inspection of the external state of the unit and check the quality of the work by running the engine.
