Removal and installation of the fuel pump

Be cautious, do not suppose dirt hit in the pump or tubes of atomizers. At installation use new sealing rings on “банджо” connections топливопровода.

ENGINES F8Q

 REMOVAL

1. On engines F8Q 620 with air conditioner, operate as follows.
2. To get access to bolts of fastening of the fuel pump, it is necessary to remove the generator and its arm.
3. Disconnect a cable of weight from the battery (address to the Head the Electric equipment of the engine for models Scenic).

If the autoradio tape recorder in your car is coded before to disconnect the battery, be convinced that you know a code.

4. Remove the generator as the engine Electric equipment is described in the Head, then operate as follows.
5. Turn away bolts of fastening and remove a pulley of the pump of the amplifier of a steering with drive a pump flange. Pay attention that at easing of bolts it is necessary to keep a pulley (for example, by means of old drive a belt).
6. Turn away bolts of fastening and remove an arm with an auxiliary directing roller drive a belt.
7. Turn away two top bolts, fastening the compressor of the conditioner of air to a generator arm.
8. Cock a manual brake, поддомкратьте a forward part of the car and establish it on axial props. Where is available, remove the bottom guard of the engine.
9. Remove the right forward wheel and the loose leaf of an arch of a wheel.
10. Loosen the the bottom fixing nuts and bolts of the compressor of the conditioner, then turn the compressor downwards that the generator arm could be removed from above.
11. For all models operate as it is described in following paragraphs.
12. If it is not executed yet, disconnect a cable of weight from the battery (address to the Head the Electric equipment of the engine for models Scenic).
13. Turn on and uncover the right top support of the engine.
14. Turn коленвал to establish the piston №1 in ВМТ on a compression step, and insert an adjusting pin to check up position коленвала as it is described in the Head engine Repair.
15. Turn away bolts of fastening and uncover gear drive a belt which closes a cogwheel of the fuel pump.

16. If there is a tool for deduction of a pulley of the fuel pump (Renault Mot. 1200), remove an adjusting pin, turn коленвал from ВМТ on one tooth of a pulley of a cam-shaft and insert into a pulley of the fuel pump keeping tool (address to an accompanying illustration).

17. If the specified tool is not present, remove gear приводной a belt as it is described in the Head engine Repair.
18. Disconnect a rope of a pedal of gas from the fuel pump, address to Section Removal, installation and adjustment of a rope of gas if it is necessary.
19. On engines F8Q 620 with a thermodrive of fast idling disconnect a rope of fast idling from the fuel pump (address to Section Removal, installation, check and adjustment of a thermodrive and a rope of fast idling). On models with a vacuum drive of fast idling disconnect a rope from the lever of the pump and a vacuum hose from a drive (address to Section Removal, installation, check and adjustment of components of system of fast idling).

20. On models with turbocharger disconnect a hose, the connecting proof-reader of giving of fuel depending on pressure of pressurisation with the inlet pipeline (address to an accompanying illustration).

21a. Turn away a bolt банджосоединения and disconnect a hose of giving of fuel from the fuel pump. Close the open end of a hose or a pipe and закупорьте a branch pipe on the fuel pump not to admit dirt penetration.

21b. The same make and with the main returnable hose (address to illustrations).

22. Disconnect the main fuel returnable hose from a fuel atomizer (address to an accompanying illustration).

23. Where it is applied, disconnect an auxiliary returnable fuel hose from the pump. On models with turbocharger, the auxiliary hose is connected with the proof-reader of giving of fuel of pressure of pressurisation on the pump (address to an accompanying illustration).

24. Disconnect all electroconducting from the pump. Pay attention that on some pumps it can be made, simply disconnecting conducting from sockets on the pump. On some pumps it is necessary to disconnect conducting from separate components (some connections can be protected rubber covers) (address to an accompanying illustration). On engines with pumps Lucas, disconnect conducting from following blocks: the coded electromagnetic valve, the proof-reader of the moment of injection and a potentiometer of the lever of gas.

25. Turn away connecting nuts, fastening tubes to the fuel pump and atomizers. Remove tubes in gathering. Close open connecting муфты not to admit dirt penetration. Pay attention that from fuel atomizers it is necessary to remove taking away hoses that it was possible to close atomizers (address to an accompanying illustration).

26. Where it is applied, remove a plastic guard of the generator below the fuel pump. Notice an arrangement of the arms attached by nuts and bolts.
27. On engine F8Q 620 operate as follows:

28. Turn away a fixing nut of a pulley of the fuel pump and remove a washer. If there is no tool for pulley deduction (address to an illustration), block a pulley the self-made tool inserted into apertures in a pulley (but not in a pulley teeth).

29. Note an arrangement of a cogwheel concerning the end of a shaft of the pump. It is necessary for making irrespective of, whether has been removed gear приводной a belt or not as in a pulley there are two cuts under segment шпонку (for use with fuel pumps of various types).

The stripper should settle down in pulley apertures, instead of on a teeth. For a pulley “МАА” the special stripper which is established on a pulley nave is required.

31. Remove a stripper. If the tool keeping a pulley of the fuel pump is established and gear приводной the belt is not removed yet, do not remove a pulley.
32. On engines F8Q 784, 786 and 788 operate as follows:

On early versions of these engines (mainly F8Q 784), the pulley “МАА” fastens to a shaft of the fuel pump a usual nut with a separate washer. Special stripper Renault (Mot Is required. 1357 - address to paragraphs 33-40 more low), established on a pulley nave. On late versions of engines (mainly F8Q 786 and F8Q 788), the pulley “МАА” fastens to a shaft of the pump a nut from nonferrous metal with a washer which operates as a stripper. The pulley can be released from a pump shaft, having weakened a nut - address to paragraphs 55-58 more low. Before to start to work, define a way of fastening of a pulley.

33. By means of special tool Renault (Mot. 1359), remove the central bolt of a cogwheel with a plate: the bolt has the left carving (address to an accompanying illustration).

34. Н a place of the central bolt twist special tool Renault (Mot.1357). Then twist bolt М12x125 in length of 40 mm in the tool to release a pulley (see an illustration).

35. On all models, turn away bolts and nuts, fastening an arm of the left support of the fuel pump to a head of the block of cylinders (address to an accompanying illustration).

36. Be once again convinced that all pipes, hoses and wires have been separated from the pump.
37. Put labels for the subsequent combination of the pump and an arm.

38a. Turn away three bolts of fastening.

38b. Cнимите the pump from an arm, leaving a pulley with gear приводным a belt on a place (address to illustrations). On engines F8Q 620 to reach to the bottom fixing bolt it is the most easier on the left side of the pump. For this procedure special tool Renault (Mot is required. 902-02). If it is not present, use a deep head and a lengthening core. On engines with pump Lucas and a type pulley “МАА”, turn away bolts the face figured key Т40 which minimum length should be 60 mm - and displace the pump back.

39. Clean segment шпонку from the end of a shaft of the pump if it is badly fixed.
40. If it is required, from the pump it is possible to turn away an arm of a rope of a pedal of gas.

ENGINES F9Q
