Removal, survey and installation gear drive a belt

If gear приводной the belt tears at the working engine, it can lead to serious damages. Replace a belt with the intervals specified in Specifications to the Head Maintenance service, or earlier if doubt rather its conditions.


 REMOVAL

1. Disconnect a cable of weight from the battery (address to the Head an engine Electric equipment)

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

2. Cock a manual brake, then поддомкратьте the forward right party of the car and establish it on axial props. Remove the right wheel. Where is available, remove the bottom guard of an impellent compartment.
3. Remove loose leaves of an arch of the right wheel.
4. Remove приводной a belt of a steering with the amplifier, then приводной a generator belt.
5. Establish the piston №1 engines in position ВМТ as the Arrangement of the top dead point (ВМТ) the piston №1 is described in Section.

6a. For deduction коленвала at easing of a bolt of a pulley, ask the assistant to include the highest transfer and to press a brake pedal. Коленвал also it is possible to block and in another way: turn away the gauge of speed/position коленвала from the top part of transmission and through an aperture for the gauge in картере couplings insert a screw-driver between a teeth of a wreath of a flywheel.

6b. Turn away a pulley bolt коленвала

6c. Then remove a pulley and a nave; notice шпонку on the end коленвала (address to illustrations).

7a. Turn away a nut of the bottom fastening of a cover of a drive.

7b. Uncover gear drive a belt (address to illustrations).

8. Be convinced that label ВМТ on a cam-shaft cogwheel specifies upwards and is combined with a label on клапанной to a cover. On some models the label on an epiploon casing should be combined with a label on a cogwheel коленвала, located at 6 o'clock, opposite to a cut under segment шпонку. On late models note a casing arrangement to facilitate the subsequent installation (address to an accompanying illustration).

9. Loosen the a nut on the mechanism of a tension gear drive a belt, turn a pulley of the mechanism of a tension counter-clockwise to reduce a tension, then tighten a nut to fix a pulley.

10a. Check up, that on a belt there were the arrows designating a direction of its rotation; if it is necessary, make them.

10b. Remove a belt from cogwheels of a cam-shaft, the water pump and коленвала. If the belt is used again, contrary to instructions Renault, do not overwind and do not break it at removal (address to illustrations).

11. Clear cogwheels and the tension mechanism. Also clear that party of a head and the block of cylinders on which it is established gear приводной a belt.

Survey

Renault recommends to replace gear приводной a belt after its each removal. If the belt tension is checked by means of the special tool it will be suitable for the further use only in the event that a tension - within the maximum deviations specified in Specifications. If - in the bottom range of admissible values, a belt it is impossible to pull a tension further, it should be replaced.

Attentively examine gear приводной a belt on all length, especially in the bases of a teeth. Replace a belt if on it there are pollution by oil or greasing. Replace all proceeding epiploons. The belt should be replaced, if will reach the maximum run. Also examine cogwheels and the tension mechanism as Removal is described in following Section, survey and cogwheel installation drive a belt and the tension mechanism.

 INSTALLATION

1a. Establish a new belt on a cogwheel коленвала so that one of adjusting strips on it was combined with labels on a pulley (in position of 6 hours, opposite to a cut under segment шпонку) and on an epiploon casing.

1b. Other strip should be combined with labels on a cogwheel of a cam-shaft and on клапанной to a cover.

1c. Having put on a belt a cogwheel коленвала and keeping a tension, put on it further a pulley of the water pump and on a cam-shaft cogwheel, then place on a pulley of the mechanism of a tension (address to illustrations).

2. Having arranged a belt on pulleys, ослабьте a nut of the mechanism of a tension also pull a belt, then again tighten a nut (address to an accompanying illustration). Not подпружинен, therefore for a tension of a belt it it is necessary to rotate the tension mechanism manually; as the lever it is possible to use a screw-driver inserted between bolts in apertures in a nave of the mechanism of a tension. Watch that adjusting labels remained combined.

3. Now it is necessary to adjust a belt tension, it can be made precisely only by means of tool Renault Mot. 1273 (SEEM C. Tronic 105.6). If this equipment is not accessible, as far as possible adjust a tension of a belt a method described more low, and after as soon as possible address on HUNDRED Renault for tension check. It is impossible to go to a long trip or to move on high speed, the tension gear drive a belt will not be checked up yet.

4. If adjustment is wrong, it will be repeatedly necessary to place the tension mechanism. The nut of the mechanism of a tension should be clamped the effort resulted in Specifications.

5. Establish a pulley коленвала and a bolt. Turn коленвал on two complete revolutions in a normal direction of rotation, then repeatedly check up a tension of a belt and be convinced that adjusting labels are correctly combined. Adjusting labels on cogwheels should be combined only through each two turns, however strips on gear приводном a belt will be combined only through some turns of the engine. Tighten a pulley bolt коленвала the effort resulted in Specifications (and tighten on the specified corner for engine K7M), keeping коленвал as it is described earlier in this Section (address to an accompanying illustration).

6. Establish a cover gear drive a belt and tighten fastening bolts.
7. Establish приводной a generator belt, then приводной a belt of a steering with the amplifier, and pull them.
8. Establish loose leaves of an arch of the right wheel, then establish a wheel and lower the car on the earth.
9. Attach a weight cable to the battery.
