Folksvagen Sharan/Sharan repair>> The power supply system of the diesel engine and turbocharger>> The fuel pump of a high pressure>> Removal and installation
To remove ТНВД, execute operations:
- Remove the air filter;
- Remove the top protection of a gear belt;
- Uncover heads of the block of cylinders;
- Establish the engine in position ВМТ. For this purpose uncover heads of the block of cylinders and turn away a stopper located in the top part of a transmission that labels on a flywheel were visible;

Fig. 415. In the top drawing the adjusting calibre established on a camshaft 1 is shown. In the bottom drawing it is shown, how the flywheel with label ВМТ should be located





- Turn a cranked shaft (by means of a key of the pulley put on a bolt) so that the label on a flywheel has appeared in the position shown on fig. 415.
- Establish adjusting calibre for a camshaft and remove поликлиновой a belt as it has been described in item 17.4.1. Remove directing roller;
- ослабьте a nut of cogwheel ТНВД, but do not turn on it completely;

Fig. 474. Removal of cogwheel ТНВД by means of the special adaptation. Strike a plastic or rubber hammer in a direction shown by an arrow on a head of a bolt to shift a cogwheel from its cone-shaped place of fastening





- Remove a cogwheel by means of a special stripper 3032. For this purpose establish a stripper on a cogwheel (fig. 474). Tighten an average bolt of a stripper so that the stripper has been pressed to a cogwheel surface, and then remove a cogwheel, striking a plastic or rubber hammer on the end of an average bolt;
- Remove a stripper, turn away a nut from the end of a shaft and remove a cogwheel;
- Disconnect all топливопроводы from ТНВД;
- Separate штекерную колодку the valve of a stopping delivery of fuel;
- Disconnect a cable of management of fuel giving;
- Note exact arrangement ТНВД to establish it then in initial position. On a flange of the pump and a fastening arm put risks which should coincide again at repeated installation ТНВД;

Fig. 476. In the place specified by an arrow the nut, which крепит back support ТНВД is located конусная




- Being guided by fig. 475, turn away three bolts on a flange fuel ТНВД and turn away the separate bolt located on a back support (fig. 476). Remove ТНВД.
ТНВД is not subject to repair. Faulty ТНВД it is necessary either to replace, or to give to repair on HUNDRED.
Order of installation ТНВД:
- Establish the pump on an arm, level it according to the put labels and tighten конусную a nut (fig. 476 see).
- Check up, that all put before a label coincided and tighten fastening bolts in regular intervals on a circle the moment 25 Нм;
- Check up, whether there is a wedge on shaft ТНВД, and cautiously put on a cogwheel a shaft. Tighten a nut the moment of an inhaling 55 Нм;
- Tighten накидные nuts топливопроводов the moment 25 Нм;
- Turn cogwheel ТНВД so that labels on a cogwheel and an arm have coincided. Fix cogwheel ТНВД in this position, having inserted a clamp 2064 (p. 200 see);

Fig. 477. Details of protection of a gear belt (in the place specified by an arrow establish оправку for removal of a cogwheel of a camshaft): 1 — a bolt, 10 Нм; 2 — a back cover; 3 — the top protection приводного a belt; 4 — the bottom protection приводного a belt; 5 — a bolt, 10 Нм; 6 — a bolt, 20 Нм





- ослабьте a bolt of fastening of a cogwheel of a camshaft on a half-turn also bring down a cogwheel a plastic or rubber hammer. It is possible to insert оправку (fig. 477) and to strike on it a plastic or rubber hammer. The camshaft cogwheel thus also will be shifted;
- Check up, whether there is an engine in position ВМТ;
- Establish a gear belt as it has been described in item 17.4.2. Spend all other works described in this section. Pull поликлиновой a belt and a belt of a drive of the hydraulic booster of the steering mechanism (corresponding sections see).
- Check up for HUNDRED moment of injection.
