1.3.3.6. Check and adjustment of gaps of valves (diesel engines)

Check

GENERAL INFORMATION

Check of gaps of valves needs to be made after emergence of knock of valves, capital repairs of the engine or at reduction of engine capacity. You make check and adjustment on the cold engine.

Combination of a tag of a pulley of a bent shaft with the index

PERFORMANCE ORDER

1. Tighten the emergency brake, lift a forward part of the car and remove the right forward wheel.

2. Uncover a head of the block of cylinders.

3. Turn a bent shaft for a bolt of fastening of a pulley of a bent shaft clockwise until the adjusting tag on a pulley of a bent shaft is combined with the index on the case of the oil pump (see rice. Combination of a tag of a pulley of a bent shaft with the index). For simplification of a provorachivaniye of a bent shaft unscrew fuel nozzles.

3. Check that cams of the first cylinder of the camshaft are directed up. If cams are directed down, turn a bent shaft on one whole revolution.

4. Draw the scheme of the engine and number cylinders from 1 to 4. The cylinder No. 1 is from a gear belt. Note position of each valve together with a valve gap. When checking gaps of valves the cam of the checked valve has to be directed up.

5. If all gaps are in the required limits, establish a cover of a head of the block of cylinders, establish a wheel and lower the car. If the actual gap does not meet standard, it is necessary to make adjustment.

Adjustment

Extraction of adjusting laying from a pusher glass

Thickness of adjusting laying

Thickness of adjusting laying is applied on one of the surfaces of laying.

PERFORMANCE ORDER

1. Rotate a pulley of a bent shaft until the cam of the valve which will need be not to adjusted is directed up.

2. Turn a pusher glass so that the flute on the top edge of a pusher was not directed to a forward part of the engine.

3. Establish a screw-driver edge between an edge of a glass of a pusher and the basis of the camshaft and move a pusher glass down so that it was possible to take laying from a pusher glass (see rice. Extraction of adjusting laying from a pusher glass).

4. Clear adjusting laying and measure its thickness by a micrometer (see rice. Thickness of adjusting laying).

5. Add the measured valve gap to thickness of initial adjusting laying then from the received number take away the required valvate gap. As a result you receive thickness of the new required adjusting laying.

For example:

The measured gap of the valve of 0,35 mm.
Plus thickness of initial adjusting laying is 2,7 mm.
Equally to 3,05 mm.
Minus the required gap of 0,25 mm.
The required thickness of laying of 2,8 mm.

6. Take adjusting laying of the required thickness, oil it pure engine and insert into a pusher glass that designation of thickness of adjusting laying was directed down.

7. Similarly adjust gaps of valves on other valves.

8. Several times turn a bent shaft of the engine and repeatedly measure gaps of valves.

9. Establish a cover of a head of the block of cylinders, establish a wheel and lower the car.
