2.22. Dismantling and assembly of the engine

We remove the engine from the car (see. "Removal of the engine") we also clear it of dirt and oil.

Cap key "on 13" we turn off two nuts, and a key "on 17" - one nut of fastening of the right arm of a forward support of the power unit and we remove it. On fixing hairpins of the right arm of a forward support we mount a plate of the dismantling stand and we fix the engine at the stand.

We take out the oil level probe index from the directing tube.

Cap key "on 10" we turn off a tube and we remove it.

Cap key "on 13" we turn off three nuts of hairpins of fastening of an arm of the left forward support of the power unit to the block of cylinders of the engine...

... also we remove an arm.

We remove the generator, a flywheel, a head of the block of cylinders, the pump of cooling liquid, the case pallet, the lower cover and a chain of the drive of the camshaft. Operations on dismantle of these knots are given in appropriate sections.

Key "on 13" we turn off two nuts of hairpins of fastening of a back arm of the generator to the block of cylinders...

... also we remove an arm.

Head "on "10" we turn off six bolts of fastening of a cover of a back epiploon of a bent shaft.

We uncover with an epiploon and sealing laying.

Key "on 10" we turn off two hairpins of fastening of an uspokoitel of a chain of the drive of the camshaft.

We remove from a sock of a bent shaft a maslootrazhatel.

We remove an oil receiver (see. "Removal of an oil receiver").

Head "on 15" we turn off two nuts of bolts of fastening of a cover of a rod (the piston at the same time has to be in NMT).

We uncover a rod with an insert.

We take out the lower insert of the conrod bearing from a cover.

Resting fingers of hands against bolts of fastening of a cover, we shift a rod up and we separate the lower head and a conrod neck of a bent shaft. Then, resting the wooden handle of the hammer against the socket of the lower head of a rod, we move a rod with the piston up a cylinder sleeve.

Pushing out the piston, do not damage a cylinder sleeve mirror conrod bolts and the lower head of a rod.

We take out the piston with a rod.

We take out the top insert of the conrod bearing from a rod head.

Similarly we take out pistons with rods from other cylinders of the engine.

We fix a rod in a vice with overlays of sponges from soft metal.

Carefully, without making big effort, unclenching fingers the lock of the top compression ring, we bring a ring out of a flute of the piston and we remove it.

In the same way we remove the second compression ring and disks of an oil scraper ring.

We remove a dilator of an oil scraper ring.

We hook a pricker and we take a lock ring of a piston finger from a ring flute in a piston lug.

In the same way we take out the second lock ring of a piston finger.

We heat the piston, having shipped it for 2-3 minutes in water with a temperature of 60-70 °C...

... and, holding a rod on weight, the hammer through a drift from soft metal we beat out a piston finger.

Two screw-drivers we hook a sleeve for the top fillet, leaning on the top privaloch-ny plane of the block of cylinders.

Not to damage strong pressing the privalochny plane of the block of cylinders, under screw-drivers it is possible to enclose wooden whetstones.

If the sleeve does not go out of the block of cylinders, it can be beaten out, striking blows with the hammer through a mandrel to its lower end face (it is more convenient to make it when the bent shaft is removed).

We take a sleeve from the block of cylinders.

Similarly we take out other sleeves.
