Remove the bolt back of the fuel pump to the bracket. Remove the fuel pump from the engine.
Setting Install the high pressure fuel pump and screw the back of the fuel pump to the bracket. Bolted the front part of the high pressure fuel pump. Install the injection pump pulley shaft and lock it in 2064 (see. Fig. 5.13). Install and tighten the moment 45 Nm high pressure pump pulley nut. Loosen half turn pulley bolt toothed belt camshaft. Through a hole in the back casing of a gear belt from the cylinder head with a hammer and punch knock toothed belt pulley with the taper of the camshaft. Fully unscrew the bolt of a pulley of a gear belt and remove a pulley from a camshaft. Make sure that the TDC mark on the flywheel is aligned pointer. Install the timing belt on the injection pump pulley and tensioner roller. Put the toothed belt on the camshaft pulley and install the pulley on the camshaft so that it could still be turned. Set the guide roller. Remove the pin from the pulley 2064 high pressure fuel pump.
| Fig. 5.15. Adjusting the tension of the toothed belt
|
Adjust the tension of the toothed belt. Wrench (for example, Matra V159) rotate clockwise the eccentric roller tensioner until the setting mark on the roller with the pointer (Fig. 5.15). Tighten the tensioner nut to 20 Nm. Re-check that the TDC mark on the flywheel is aligned pointer. Tighten the pulley bolt toothed belt camshaft belt to 45 Nm. Turn the hand crankshaft two turns.
Adjustment
| Fig. 5.16. Installing the adapter 3313 with a dial gauge to adjust the fuel injection timing
|
Remove the drain plug from the high pressure fuel pump and instead screw the adapter 3313 with a dial indicator (Fig. 5.16). Set the dial indicator to 2 mm and tighten the adjusting nut on the adapter. For the central pulley bolt to turn the crankshaft clockwise until the arrow until the indicator stops moving. Set the dial indicator to 1 mm. For the central pulley bolt to turn the crankshaft clockwise to align the TDC mark with a pointer or end line setting device 2068A. Read the dial indicator, which shall be (0,7 ?� 0,02) mm. If the reading on the display is not correct, adjust injection timing, turning the fuel pump. Tighten the fuel pump to 25 Nm. Remove the adapter and replace the drain plug, tightening it to a torque of 20 Nm. Further installation is carried out in sequence, return to removal, taking into account the following. Fill the fuel pump diesel. To do this, the hole for connecting the fuel return hose connected via a transparent hose length of 1 m and a vacuum pump to apply a vacuum. When the fuel in a transparent hose disconnect and reconnect the hose to the pump fuel return. Connect a wire of "weight" to the battery. Turn on the radio and enter the code. Lift up the power window glass until it stops. Then click on all window switches again for at least 1, in the closed position of the control unit to activate windows. Set the clock. After separation of the various electrical connections in the memory control unit writes error information to be erased after installation. Start the engine and check the tightness of supply.
Six-cylinder engine pump Withdrawal Before disconnecting the battery, check whether you have the code switch on the radio. Switch off the ignition and disconnect a wire of "weight" from the storage battery. Install the front transverse panel in service position.

|
A WARNING Chalk, markers or paint mark the direction of rotation of the toothed belt. After setting the belt rotates in the opposite direction, which may result in its destruction. |
Remove the pump with high pressure pipes. Disconnect from the pump pressure line.
Setting Install the fuel pump and secure it with screws, tightening the bolts of the pump to the cylinder head to 20 Nm and bolts to the rear toothed belt to 10 Nm. Install the pressure and screw them to the pump, tighten the nuts to 30 Nm.

|
Set the pump drive pulley on a camshaft so that the bolts were placed in the middle of the elongated holes of the pulley. Tighten the screws so that you can turn the pulley on the pump camshaft pulley. Install the timing belt pump. Adjust the tension of the toothed belt pump, for which an Allen key, turn the tensioner anti-clockwise before combination of labels 1 (Fig. 5.24), and a second wrench to tighten the nut to 36 Nm. Tighten the camshaft pulley to 20 Nm. Remove the pin 3359, fixed pulley of the fuel pump. Remove the set screw 3242, fixed crankshaft. Turn the hand crankshaft two turns. Recheck the tension of the toothed belt drive of the fuel pump and, if necessary, repeat the adjustment (see. Fig. 5.24). Install the damper pulley of the fuel pump and fix its bolts, having tightened their moment of 20 Nm. Replace the front section of the intake manifold, and fix bolts, having tightened their moment of 10 Nm. Connect the electrical connector to the high pressure fuel pump. Connect the fuel hoses. Bleed the fuel system. Establish a casing of a gear belt. Connect a wire of "weight" to the battery. Turn on the radio and enter the code. Lift up the power window glass until it stops. Then click on all window switches again for at least 1, in the closed position of the control unit to activate windows. Set the clock. After separation of the various electrical connections in the memory control unit writes error information to be erased after installation. Start the engine and check the tightness of supply.
