Engine of 1,6 l

Removal

 PERFORMANCE ORDER

  1. Remove a gear belt, a forward cover, a flywheel and the oil pallet.
  2. Remove a back cover from the block of cylinders and a back sealing ring of a cranked shaft.
  3. Unscrew nuts and remove covers of rods.

Mark covers of radical bearings of a cranked shaft to establish them on the places and in the same situation.

  1. Turn out bolts and remove covers of radical bearings of a cranked shaft and a cranked shaft.
  2. Remove a rotor of the sensor of an angle of rotation of a cranked shaft.

Check

 PERFORMANCE ORDER

  1. Check necks of radical and shatunny bearings of a cranked shaft on lack of wear and development. Check lubricant openings of a cranked shaft on lack of a contamination.
  2. By micrometer measure diameters of necks of a cranked shaft in two opposite directions. In the presence of a konusnost or ovality перешлифуйте a cranked shaft.

Diameter of radical necks:

- l engines 1,8 and 2,0: 57 mm;
- engines of 1,6 l: 50 mm.

Diameter of shatunny necks: 45 mm

Konusnost and ovality of necks of a cranked shaft:

- l engines 1,8 and 2,0: no more than 0,01 mm;
- engines of 1,6 l: no more than 0,005 mm.

Loose leaves of shatunny and radical bearings

Check shatunny and radical loose leaves on absence of local corrosion, development and other damages. If necessary, replace loose leaves.

Measurement of a gap of radical and shatunny bearings

For measurement of a gap of radical and shatunny bearings measure diameters of necks of a cranked shaft and the corresponding internal diameters of bearings.

The size of a gap is a difference between internal diameter of the bearing and the corresponding diameter of a neck of a cranked shaft.

Gap of radical bearings:

- l engines 1,8 and 2,0: 0,028–0,048 mm;
- engines of 1,6 l: No. 1, 2, 4, 5: 0,022–0,040 mm;
- No. 3: 0,028–0,046 mm.

Gap of shatunny bearings:

- l engines 1,8 and 2,0: 0,024–0,044 mm;
- engines of 1,6 l: 0,018–0,036 mm.

Oil sealing rings

Check lobbies and back oil sealing rings on absence of damages or wear of working edges. In the presence of any defects replace a sealing ring.

Covers of bearings

After installation of covers of bearings turn a cranked shaft and be convinced that it rotates easily and smoothly, and its axial люфт corresponds to the values given in the specification.

Axial люфт cranked shaft: 0,06–0,26 mm.
Maximum permissible axial люфт cranked shaft: 0,30 mm.

Rotor of the sensor of an angle of rotation of a cranked shaft

 PERFORMANCE ORDER

  1. Remove a rotor of the sensor of an angle of rotation of a cranked shaft.
  2. Check a rotor of the sensor of an angle of rotation of a cranked shaft on absence of damages, cracks and wear and replace if it is necessary.
  1. Check a gap between a rotor of the sensor of an angle of rotation of a cranked shaft and the sensor of an angle of rotation of a cranked shaft. A gap between a rotor of the sensor of an angle of rotation of a cranked shaft and the sensor of an angle of rotation of a cranked shaft: 0,5–1,1 mm.
  1. Measure depth of installation of the sensor, i.e. distance from the top part of teeths of a rotor of the sensor of an angle of rotation of a cranked shaft to outer side of a cover.
  2. Calculate a difference between length of the sensor of an angle of rotation of a cranked shaft and depth of its installation.

Choice of loose leaves of radical bearings of the engine of 1,6 l

 PERFORMANCE ORDER

  1. Check a code of the size of an opening for a cranked shaft in the block of cylinders.

Write down an alphabetic code of the size of an opening for a cranked shaft in the block of cylinders. The reading order – from left to right, thus the first code corresponds to the size of a forward opening in the block of cylinders.

Installation

 PERFORMANCE ORDER

  1. 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.
  2. Before installation of a cranked shaft apply a thin film pure engine oil on all surfaces of sliding. Establish a cranked shaft on loose leaves of radical bearings in the block of cylinders.
  3. Establish the remained loose leaves of radical bearings in covers of radical bearings of a cranked shaft. According to marking establish covers of radical bearings of a cranked shaft, thus the arrow on each cover should be directed to a pulley of a cranked shaft. In a certain sequence for 2 or 3 stages tighten bolts of fastening of covers of radical bearings of a cranked shaft in the following order: central, No. 2, No. 4, forward and back.

Inhaling moment:

Covers of radical bearings:

- l engines 1,8 and 2,0: 27–33 N • m + tighten on a corner (60–65) °;
- engines of 1,6 l: 55–60 N • m.

Covers of shatunny bearings:

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

  1. Turn a cranked shaft and check that it rotates easily and smoothly. Shchup inserted between a persistent half ring and cranked shaft, check axial люфт a cranked shaft.

Axial люфт cranked shaft:

- l engines 1,8 and 2,0: 0,06–0,260 mm;
- engines of 1,6 l: 0,05–0,175 mm.

Axial люфт rod: 0,10-0,25 mm.

  1. Grease an external surface of a new back sealing ring with engine oil. The special tool 09231-22000 establish a sealing ring against the stop in a nest of a back cover.
  1. Establish a cover of a sealing ring, laying and tighten bolts. At installation grease working edges and an external surface of a sealing ring with pure engine oil.
  2. Establish covers of rods.
  3. Establish a flywheel, a forward cover, the oil pallet and a gear belt.
