Arrangement of the top dead point (ВМТ) for the piston №1

The mentioned adjusting pins are intended ONLY FOR position check коленвала at performance of various procedures of a partition of the engine. Do not use them as blocking tools to keep коленвал motionless at easing or a tightening of bolts of a pulley or a disk flywheel/privodnogo.

ВМТ - the highest point in the cylinder which reaches the piston at a turn коленвала. Each piston rises in ВМТ in the end of a compression step, and also in the end of a release step. However for adjustment of the moment of ignition it is taken into account ВМТ in the end of a compression step. On all engines described in this management, the cylinder №1 is in the end of the engine turned to transmission.

CHECK

1. Remove a casing of the air filter as it is described in the Head of the Power supply system, release to get access to a control aperture of a flywheel/privodnogo of a disk in картере couplings. 2. Now turn коленвал while the adjusting label on a cam-shaft cogwheel does not become in position of 12 hours and the label on a flywheel/privodnom a disk will not be combined with label ВМТ (0 °) on картере transmission couplings. To see an adjusting label on a cam-shaft pulley, on the majority of models it is required to turn away fastening, to let out скобы (where are applied) and to remove the top external cover gear drive a belt. Pay attention that on some models will probably combine a label on a pulley with the index in an aperture of a cover gear drive a belt. 3. Коленвал it is possible to turn a wrench for a pulley bolt. Pay attention that коленвал always should rotate clockwise if to look on the right side of the car. 4. Turn коленвал, watching a label on a cam-shaft cogwheel. When the adjusting label on a pulley will be correctly placed, the label on a flywheel/privodnom a disk should be combined with label ВМТ (About °) on transmission. Now the piston №1 is established in ВМТ on also compression. 5. Absolutely precisely position коленвала can be checked up, inserting an adjusting pin - tool Renault Mot. 861 (the early version) or Mot. 1054 (the latest version). For this purpose turn on заглушку from the forward left end of the block of cylinders, near to the tube basis probeа measurements of level of oil and insert an adjusting pin so that it has entered into a groove in коленвале. Probably it is necessary to turn slightly коленвал forward or back (address to an accompanying illustration). The note Do not try to rotate the engine with the established pin. If the engine is necessary for leaving in this condition for long time, in an impellent compartment it is recommended to leave to start with the prevention.

CHECK

1. Remove auxiliary приводной a belt as Maintenance service is described in the Head. 2. Turn away bolts and remove a plastic cover from the right support of the engine, then disconnect a cable of weight of the engine. 3. Remove strengthening core (where is available) between domes of a forward suspension bracket. 4. Release the tank of hydrosystem of the amplifier of a steering and move it aside. 5. The top arm of the right support of the engine is necessary for removing, that it was possible to take the top external cover gear drive a belt; therefore the engine is necessary for supporting a jack or лебедкой. 6. Check up, that engine/transmission assemblage has been reliably supported, then turn away a nut, крепящую the top arm to assemblage of the terminator of movement / to a rubber pillow - be guided by Section of the Support of the engine/transmission - survey and replacement. 7. Disconnect submitting and returnable fuel hoses from a fuel highway. Then закупорьте the ends of hoses. 8. Release fuel hoses from fastening on an intermediate external cover drive a belt. 9. Ask the assistant to include 4th transfer and to press a brake pedal. 10. Turn away bolts and remove the bottom, intermediate and top external covers gear drive a belt (address to illustrations above). 11. Temporarily establish a pulley bolt коленвала that коленвал it was possible to turn. 12. Turn коленвал while the adjusting label on a cam-shaft cogwheel does not become in position of 12 hours (it will be combined with a label on an internal cover of a gear belt) (address to an accompanying illustration). 13. Turn коленвал, watching a label on a cam-shaft cogwheel. When adjusting labels on a pulley become everyone on the place, the piston №1 will be established in ВМТ on also compression. 14. Absolutely precisely position коленвала can be checked up if to insert an adjusting pin - address to paragraph 5 above and illustrations to it. Probably it is necessary to remove assemblage of the air filter both various tubes and hoses to get access to заглушке. 15. Establish all disturbed components in the return to removal an order. Tighten all nuts and bolts the effort resulted in Specifications where it is given.
