Turn away a nut and uncover a rod and the bottom loose leaf шатунного the bearing. For protection of necks of a cranked shaft dress on bolts of fastening of covers of rods pieces of a rubber or plastic tube.

Establish universal support in a clip between a rod and the piston.

Stripper squeeze out a piston finger from the piston.

Establish the piston in gathering on a clip thus directing a pin supports a rod in a piston finger. Be convinced that the piston approaches on a clip while the directing pin will not contact with вилочной an insert. Check up correctness of a relative positioning of the piston and a rod and, rotating a nut with накаткой, fix the numbered plug on a shaft.

Check up an external surface of the piston on absence of damages, development or non-uniform deterioration. If necessary, replace the piston. Check up each piston ring on absence of damages and non-uniform deterioration. If necessary, replace piston rings. At piston replacement also it is necessary to replace piston rings. Check up a piston finger, inserting it into a piston aperture. The piston finger should enter smoothly into the piston by pressing it a hand (at a room temperature).

Insert a new piston ring into a flute of the piston and щупом measure a backlash between a piston ring and a flute wall. If the backlash exceeds maximum permissible value, replace the piston.

Backlash between a piston ring and a flute in the piston:

The first компрессионное a ring:

- Engines of 1,8 and 2,0 l: 0,04–0,08 mm;
- Engines of 1,6 l: 0,04–0,085 mm.

The second компрессионное a ring:

- Engines of 1,8 and 2,0 l: 0,03–0,07 mm;
- Engines of 1,6 l: 0,04–0,085 mm.

Measure a backlash in the lock of piston rings, manually having inserted a piston ring into the engine cylinder. The piston bottom push a piston ring in the bottom part of the cylinder. Щупом measure a backlash in the lock of a piston ring.

Backlash in locks of piston rings:

The first компрессионное a ring:

- Engines of 1,8 and 2,0 l: 0,23–0,38 mm;
- Engines of 1,6 l: 0,15–0,30 mm.

The second компрессионное a ring:

- Engines of 1,8 and 2,0 l: 0,33–0,48 mm;
- Engines of 1,6 l: 0,30–0,45 mm.

Maslosemnoe ring:

- Engines of 1,8 and 2,0 l: 0,20–0,60 mm;
- Engines of 1,6 l: 0,20–0,70 mm.

Maximum permissible backlash:

The first and the second компрессионные rings: 1,0 mm.
Maslosemnoe ring: 1,0 mm.

Marks are put on the top part of a piston ring, from outside the lock.

At installation be convinced that the rod and a rod cover correspond to cylinder number in which they are established. At installation of a new rod make sure that the labels defining its position, are from the same party as a label on other rods.

Choose the piston which diameter corresponds to a cylinder class. A backlash between the piston and the cylinder: 0,025 – 0,045 mm.

Apply a thin film engine oil on the piston and piston rings.

Пассатижами for a release of piston rings establish компрессионное a ring №1.

The special adaptation compress piston rings on the piston. Establish the piston with piston rings over the first cylinder, thus the label on the piston should be directed to a forward part of the block of cylinders. The hammer handle press the piston into the cylinder so that the bottom head of a rod was established on a neck of a cranked shaft. Establish the top loose leaves of radical bearings on the block of cylinders of the engine. At repeated installation of loose leaves establish them on the same places on which they were before removal. Establish loose leaves of radical bearings in covers of radical bearings of a cranked shaft. Be convinced that labels on the piston and a rod are directed to a forward part of the block of cylinders. At installation of a new rod be convinced that dredging for the bearing loose leaf are on the one hand. Tighten bolts and nuts of fastening of covers of rods.
With engine oil grease a carving of nuts and bolts; The demanded moment tighten bolts and nuts of fastening of covers of rods.

The inhaling moment:

- Engines of 1,8 and 2,0 l: 50–53 Nm;
- Engines of 1,6 l: 32–35 Nm.

Щупом, inserted between a rod and cranked shaft, measure a lateral backlash of a rod. A nominal lateral backlash of a rod: 0,10–0,25 mm. A maximum permissible backlash: 0,40 mm Establish the oil filter. Establish the oil pallet. Establish a head of cylinders.
