Piston rings - a circular metal parts of an open form.They are installed in the grooves of the outer surface of the piston.As practice shows, the service life of these components is 100-120 thousand kilometers (about the piston rings are VAZ).However, there are elements that can withstand and the 300,000th service.The range in which the piston rings are replaced, really different, so in time to define the problem, you need to pay attention to the following factors:
- loss of engine power;
- appearance of blue smoke from the exhaust pipe;
- reduction in compression;
- increased waste oil.
If you have noticed at least one of these signs, you should think about replacing the piston rings.With the purchase of a new part it is very easy to handle, but with its setting quite the opposite.So you do not get confused in the order of the steps below, we describe in detail how replacing piston rings.
first merge antifreeze and disconnect the throttle cable to the receiver and the throttle assembly.Then dismantle the protection of the timing belt.Then weaken slightly clamps and remove the hose throttle knot.Now find the item, which is using the supply of crankcase gases.It should be a little hose located on the valve cover.And we have just removed and disconnect a wire of weight.It is situated on the cylinder head.Then dismantle the fuel line.To do this, take the open-end wrench 17 mm and unscrew all the fastening bolts.Recent best mark, so then there were no problems with the installation.
then move the thermostat previously unscrewing its nuts fasteners.If necessary, remove from it hoses.Next, disconnect the regulator of idling and throttle sensor.Now remove the tensioning pulley and remove the belt.Next, unscrew the fastening of a pulley of a cam.After that, take out the element otkruchenny out.When disassembling, take care not to lose the key.Now we need to look at the bottom of the fasteners connecting the collector pipe.They too should be removed.Next, disconnect the crankshaft position sensor and the oil level.Now you need to unscrew the bolts that secure the cylinder head.Then remove the cylinder head and take out the stopper on the pallet.Drain the oil and then disconnect the protection of the flywheel.The tray is also removed.Then take out the rod cover.But the replacement of piston rings is still not finished.After the above steps retrieve connecting rod and piston group and clear it from the deposit.
Now you only install the piston rings.First Look marking pistons and reconcile it with the data of the purchased parts.Then insert the ring into place and adjust them.Mount parts to the same place where the old were installed.Next, put the cover on the connecting rods and tighten them.Now we have to assemble everything in reverse order.
all, at this stage of the replacement piston rings successfully completed.You can start the engine again.
