words "engine overhaul" for every motorist sounded like a death sentence to hear that, just right to fall into despair.But is he afraid of?In fact, the overhaul of the engine can be significantly cheaper, especially for high-value automobiles.The fact that the engine of any car - it is, in fact, just iron, and, no matter how difficult it may be, they are all very similar.All have pistons, piston rings, crankshaft.Of course, some larger valves, in some - camshafts, cylinders, but they all operate according to the principle of four cycles, which makes them almost identical.
engine overhaul roads, especially parts that are, say, for cars produced in Germany are at times greater than for the other brands of machines producing countries.But do not forget that for the work of the mechanics, too, you can shell out decent.
VAZ engine overhaul can be carried out in his garage, enough to stock up on simple set of tools, among which should be a gas burner, as the piston pin into the upper connecting rod inserted at a temperature of 750-800 degrees.
First of all, we must note that the repair of the engine means its complete dismantling, so care must be taken in a timely manner a clean workplace, better carry out the work on the removed engine without attachments.Also, you need to stock up a solid amount of kerosene required "bath" shaft, as well as other details.
If the engine is removed, then the work should be divided into three parts: the cylinder head, block itself, as well as lubrication.And now - on and in detail.
First you need to analyze everything in detail, but it is worth remembering that the valve mechanism that can not be replaced, should be installed in the same manner as that of standing.The valves, after replacement and replacement of the sleeves have to be lapped by lapping pastes.Camshaft (or shafts, if there are two or more) worth fathom micrometer and if there is a deviation from the norm, to be replaced.You also need to pay attention to their support, as they are usually made of cast aluminum (rather soft material, which has less strength).
Now a bit about the engine block.It is only in the repair of replacement.Of course, if you have a home machine for boring and honing of the cylinders, all the work you will be able to fulfill themselves, but such people are very few.Therefore, the block itself is to give to a special workshop where specialists work.
After he returns, it will nasechen class pistons, which should pick up.For each class has its own class of piston pins and piston rings.The weight of each cylinder should ideally be identical, but may be an error in the 2 grams.
Go ahead.Next on the list lubrication system.Engine overhaul and repair involves the system, because it is responsible for the safety and durability of the parts.Here, again, you need a micrometer to determine whether grinding the crankshaft journals.If so, then we must do the same as with the unit.If not - you just replace the pads.Their size is usually indicated in the repair of the cheeks balances.If size is not specified, the neck never polished, then it corresponds to the nominal value.
After all these transactions are assembled and replacing consumable liquids and filter elements.Before the trial run is recommended to pour oil into the oil filter and crank by hand.From the foregoing it follows that the engine overhaul with their hands - it's not so bad, since nowadays difficult to find any manual.
