Unscrew nuts and uncover a rod and the bottom loose leaf of the shatunny 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 assembled 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 a vilochny insert. Check correctness of a relative positioning of the piston and a rod and, rotating a nut with a nakatka, fix the numbered plug on a shaft.

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

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

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

First kompressionny ring:

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

Second kompressionny ring:

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

Measure a gap in the lock of piston rings, having manually inserted a piston ring into the engine cylinder. The bottom of the piston push a piston ring in the lower part of the cylinder. By Shchup measure a gap in the lock of a piston ring.

Gap in locks of piston rings:

First kompressionny ring:

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

Second kompressionny ring:

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

Maslosjemnoye ring:

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

Maximum permissible gap:

First and second kompressionny rings: 1,0 mm.
Maslosjemnoye ring: 1,0 mm.

Marking is put on the top part of a piston ring, from the lock.

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

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

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

To Passatizhami for a release of piston rings establish a kompressionny ring No. 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 handle of a hammer 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 loose leaf of the bearing is 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.

Inhaling moment:

- l engines 1,8 and 2,0: 50–53 N • m;
- engines of 1,6 l: 32–35 N • m.

Shchup inserted between a rod and cranked shaft, measure a lateral gap of a rod. Nominal lateral gap of a rod: 0,10–0,25 mm. Maximum permissible gap: 0,40 mm Establish the oil filter. Establish the oil pallet. Establish a head of cylinders.
