11. Nut of the pipeline of discharge of fuel

Removal
PERFORMANCE ORDER
1. Disconnect wires from plugs of the rechargeable battery.
2. On cars with the air-air heat exchanger disconnect electric wires from the cooler electric fan, disconnect air hoses from a cooler, turn off four bolts of fastening of an arch and remove all knot.
3. Disconnect a compensation hose of a turbo-supercharging.
4. Disconnect electric wires from the pump (see rice. Fuel pump of high pressure).
5. Disconnect pipelines of a supply and removal of fuel, a cable of management of supply of fuel and pipelines of high pressure from the pump.
6. Remove the top cover of the drive of the gas-distributing mechanism.


7. Rotating a bent shaft clockwise a key for a bolt of fastening of a pulley, combine tags on a pulley of the camshaft (1) and a pulley of the TNVD drive with adjusting pins (2) on the block and weaken a tension of a gear belt.


8. Turn off a nut of fastening of the cogged pulley of the TNVD drive and remove a pulley (2) by means of a stripper (1). Turn off two forward bolts of fastening of TNVD.
9. Remove a back arm of fastening of the pump then remove TNVD.

Installation
PERFORMANCE ORDER
1. Screw two forward bolts of fastening of the pump and establish into place a back arm of fastening of the pump.
2. Install the cogged pulley of the TNVD drive, screw and tighten a pulley nut the moment of 8,0-9,0 kgfs/m.
3. Put on a gear belt a TNVD drive pulley, previously having combined adjusting tags.
4. Adjust an initial corner of an advancing of supply of TNVD fuel as it is described below.
Tighten bolts of fastening of the pump.
5. Establish the top cover of the drive of the gas-distributing mechanism.
6. Attach pipelines of high pressure, a cable of management of fuel supply, pipelines of a supply and removal of fuel to the pump.
7. Attach a hose to the proofreader of supply of fuel on pressure of pressurization of the pump.
8. Connect electric wires to the pump.
9. Install into place the air-air heat exchanger if it is available.
10. Connect wires to plugs of the rechargeable battery.
11. Start the engine and check its work idling.

Adjustment of an initial corner of an advancing of supply of TNVD fuel
PERFORMANCE ORDER
1. Turning a bent shaft clockwise a key for a bolt of fastening of a pulley, install the piston of the 1st cylinder in VMT of the end of a step of compression.
2. At the same time the tag on a pulley of a bent shaft has to be opposite to a tag of TDC ("VMT") on the lower cover of the drive of the gas-distributing mechanism.
3. Turn out a carving stopper which is in a back part of the pump between unions of pipelines of high pressure.


4. Under a stopper screw a rack of MD in an opening 998384, previously having convinced that its mobile probe acts on 10 mm (1 – the indicator, 2 – TNVD).
5. Fix the indicator on the end of a rack.
6. Turn a bent shaft counterclockwise so that the piston of the 1st cylinder was installed approximately in 30 ° to VMT.
7. In this situation set an arrow of the indicator to zero. Slightly turning a bent shaft in that and other party, be convinced that the arrow of the indicator does not respond.
8. Otherwise repeat the previous operation.
9. Turning a bent shaft clockwise, combine the tag corresponding to a corner of an advancing of injection of fuel on 2 °, 5 ° and 7 ° after VMT (depending on engine model), on a pulley of a bent shaft with an adjusting tag on the lower cover of the drive of the gas-distributing mechanism.
10. The indicator has to show 1±0,03 mm in this provision.
11. If the indicator shows other size, then weaken two forward bolts of fastening of the pump and bolts of fastening of a back arm of the pump.
12. Release the union of pipelines of high pressure.
13. If indication of the indicator there is less required size, displace the pump to the engine and vice versa.
14. Tighten forward bolts of fastening of the pump and bolts of fastening of a back arm of the pump.
15. Tighten the union of pipelines of high pressure.
16. Remove the indicator and turn out an indicator rack from the pump.
17. Screw a carving stopper in a pump opening, previously having replaced laying.
