Removal, installation, check and adjustment of a thermodrive and rope of fast idling

At installation the new sealing ring is required.

The following procedure is applicable only to models with engine F8Q 620 (with fuel pump Bosch and without air conditioner).

 REMOVAL

1. The thermodrive is on the left end of a head of the block of cylinders (address to an accompanying illustration).

2. Partially merge a liquid from cooling system as Maintenance service is described in the Head.

3. Loosen the the screw or a nut also remove a tip from a rope on the lever of fast idling on the fuel pump (address to an accompanying illustration).

4. Pull down a casing of a rope from an arm on the fuel pump.

5. Turn away a thermodrive from a head of the block of cylinders and remove a drive together with a rope. Clean a sealing ring (address to an accompanying illustration).


 INSTALLATION

1. Establish a drive into place, using a new sealing ring, and tighten it.
2. Fill cooling system as Maintenance service is described in the Head.
3. Insert a rope casing into an arm on the fuel pump.
4. Insert a rope into the lever of fast idling and place a tip on a rope, do not clamp while the screw or a nut.
5. Adjust a rope as it is described in following paragraphs.


 CHECK AND ADJUSTMENT

During this procedure it is necessary to measure engine turns. The usual tachometre which works from impulses of system of ignition, on diesel engines cannot be used. For this purpose is available diagnostic муфта to which diagnostic equipment Renault is connected, but it usually is not accessible to the motorist. If you cannot adjust idling turns on hearing or by means of a tachometre on the instrument panel, it is possible to use following recommendations.
a) Buy or borrow a corresponding tachometre.
b) Charge work HUNDRED Renault or to other expert.
Use a comparative method. The stroboscope copes the petrol engine, working on desirable speed. If a stroboscope to direct on a label on a cogwheel of a cam-shaft or the fuel pump, the label will seem motionless when turns of both engines it is identical (or multiple to an integer). The pulley will rotate with половинной in the speed коленвала, but it will not influence adjustment.

1. Warm up the engine (the cooling fan should join) and allow it to idle (address to Section Check and adjustment of turns of idling and delay turns), operate further as follows.

2. Move the lever of fast idling on the fuel pump to a flywheel so that it has concerned the screw of adjustment of fast idling (address to an accompanying illustration).
And — the Lever of fast idling
In — the gas Lever
1 — the Screw of adjustment of fast idling
2 — the Screw of adjustment of idling
3 — the Screw of adjustment of turns of delay
4 — the Screw of adjustment maximum engine turns

3. Be convinced that turns of fast idling corresponds to the data resulted in Specifications. If it is necessary, ослабьте a counternut and rotate the adjustment screw to achieve specified in Specifications of turns of fast idling. In summary tighten a counternut.
4. Switch off the engine and disconnect a tachometre.
5. Now it is necessary to adjust a rope of fast idling. It becomes as follows.
6. The engine should be heated-up to normal working temperature, and the lever of fast idling to stand in a starting position (to concern the screw of adjustment of turns of idling, but not the screw of adjustment of fast idling). Cautiously pull a rope of fast idling.

7. Arrange a tip on a rope so that the distance between edge of the lever of fast idling and a tip was equal 6.0 1 mm (address to an accompanying illustration).
And — the Lever of fast idling
With — a rope Tip
1 — the Screw of adjustment of fast idling
х = 6.0 mm

8. Correctly having placed a tip, tighten the screw.
9. When the engine will cool down, check up, that the rope has taken away the lever of fast idling so that it concerned the screw of adjustment of fast idling. Warm up the engine to normal working temperature and again check up, that the size “х” between edge of the lever of fast idling and a rope tip corresponded to the resulted data (address to an illustration above). If it not so, the thermodrive is possibly faulty.
