2. Uncover a gear belt.
3. Disconnect from tube and wire atomizers.
4. Remove a roller spring натяжителя a gear belt (the big efforts not
To apply).
5. Turn away a bolt and remove a roller натяжителя.
6. Remove a gear belt (is subject to replacement).
7. Fix an asterisk of the fuel pump from проворачивания for what screw bolt М6х1,25 in a carving aperture in the case through an aperture in an asterisk.
8. Turn away bolts of fastening of an asterisk of a drive to the platen of the fuel pump.
9. Press an asterisk of a drive from the platen of the fuel pump.

Installation

PERFORMANCE ORDER
1. Tighten bolts of fastening of an arm of the fuel pump, bolts of a back arm to the full do not tighten.
2. Напрессуйте a drive asterisk on the platen of the fuel pump, having combined шпонку with a flute, tighten a bolt with the moment 57–70 Н.м.
3. Establish the piston of 1st cylinder in ВМТ a compression step.
4. Combine labels on an asterisk of a drive of the pump and on a camshaft asterisk.
5. Dress a new gear belt in a following order: an asterisk of a cranked shaft, a camshaft asterisk, an asterisk of a drive of the pump. The belt weak point should have on a site between asterisks of a drive of the pump and a camshaft.
6. Establish the centre of a tension and a roller натяжителя so that the centre was between two pins on the case.
7. Tighten a roller nut by hand, the roller should rotate freely.
8. Establish a spring of a roller and tighten a nut of a roller with the moment 29–48 Н.м.
9. Turn a cranked shaft on 2 complete revolutions clockwise, then tighten a cranked shaft on 90 With to expose the pump at the moment of injection.
10. Ослабьте a roller nut натяжителя to choose a belt weak point, tighten a nut with the moment 108–130 Н.м.
11. Establish a pump flange. The aperture on a flange edge should be combined with a triangular label on a pump asterisk.
12. Turn a cranked shaft on 2 complete revolutions clockwise and establish the piston of 1st cylinder in ВМТ a compression step. Be convinced that the aperture on a flange edge was combined with a triangular label on a pump asterisk then check up a belt tension.
13. Establish a cover of a gear belt.
14. Connect the battery to weight.
