Check and adjustment клапанных backlashes should be made at the cold engine.


 PERFORMANCE ORDER

  1. Remove обтекатель a windscreen (the Body see the Head).
  2. Remove top распорку an impellent compartment (the Body see the Head).
  3. Remove a protective casing of the right wing.
  4. Empty cooling system (the Section Replacement of a cooling liquid (ОЖ see)).
  5. Remove a decorative cover of the engine.
  6. Remove assemblage of the delivery chamber of an inlet air path (see the Head of the Power supply system and release of the fulfilled gases).
  7. Remove spark plugs (the Section Check and replacement of spark plugs see).
  8. Disconnect the top hose of a radiator.
  9. Remove heads of cylinders (the Engine see the Head).
  10. Result the piston of the first cylinder in position ВМТ (the Engine see the Head).
  11. With the help щупа measure клапанные backlashes between pushers of valves and camshaft cams. Write down results of measurements and compare them to requirements of Specifications of the Head of Adjustment and car routine maintenance. The given information is required further at selection of adjusting washers.
1 — Final valves of the right number of cylinders
2 — Inlet valves of the right number of cylinders
3 — Inlet valves of the left number of cylinders
4 — Final valves of the left number of cylinders
  1. Turn a shaft on 240 hailstones. (2/3 turns) clockwise also make measurement клапанных backlashes.
1 — Final valves of the right number of cylinders
2 — Inlet valves of the right number of cylinders
  1. Then turn a shaft on 240 hailstones. Also check up backlashes of the remained valves.
3 — Inlet valves of the left number of cylinders
4 — Final valves of the left number of cylinders
  1. Turn a cranked shaft for a pulley so that the cam of the valve subject to adjustment on distributive to a shaft was developed by a working ledge upwards.
  1. Develop a valve pusher риской towards a spark plug (perpendicularly camshaft). By means of the adaptation (A) squeeze out a pusher, place between a pusher and a camshaft the adaptation (B) and clean the adaptation (A).

Establish the adaptation (B) under a small corner on the party designated in figures "7" or 9 in position. Do not get the adaptation too deeply not to jam a washer.

  1. Take an old adjusting washer by means of a small screw-driver and a magnet, measure its thickness by a micrometer and calculate a thickness of a new washer under the following formula:

N = Т + (AND - V)

Where:

Т – the Thickness of an old adjusting washer;

And – Size measured клапанного a backlash;

V – the Demanded size клапанного a backlash (Specifications of the Head of Adjustment and car routine maintenance see);

N – the Demanded thickness of a new adjusting washer.

  1. Pick up a new adjusting washer in the thickness allowing as more as possible precisely to approach клапанный a backlash to demanded value. Adjusting washers of 17 standard sizes in a range from 2.500 to 3.300 mm with step of 0.050 mm are issued.

In some cases removed from a pusher of one valve the old washer can approach for installation on a pusher of another, requiring adjustment, the valve, - do not hasten to get replaceable washers.

  1. Wring out a pusher, establish on it the picked up new adjusting washer and make sure of correctness of the made updating.
  2. Operating in a similar manner, adjust all клапанные backlashes.
  3. Establish all acting in film components in sequence, return to removal.
