Removal

PERFORMANCE ORDER
1. Remove a casing of the injecting pump.
2. Establish cylinder N1 piston in ВМТ. Mark position of mark ВМТ on a pulley / to an asterisk of the pump (1) in relation to the pump case. Mark case position in relation to mark ВМТ in a fixing arm (2).
3. Turn off a fixing bolt, keeping an asterisk.
4. Keep a pulley of the injecting pump motionlessly by means of the similar tool.
5. Turn off a nut and remove an asterisk / a pulley.
6. Remove шпонку.
7. Turn off nuts of connections and remove fuel tubes.
8. Close the ends of tubes.
9. Disconnect fuel hoses from the pump.
10. Mark and disconnect wires from the injecting pump.
11. Turn off fixing bolts and remove injecting pump from a fixing arm.

Installation and adjustment

PERFORMANCE ORDER
1. Establish injecting pump on a fixing arm, having combined adjusting marks (arrow).

2. Twirl fixing bolts (arrows).
3. Establish an asterisk / a pulley and tighten a fixing nut.
4. Establish приводной a belt.
5. Establish a cranked shaft and the pump in position ВМТ.
6. Remove adjusting заглушку from the pump.
7. Establish an adapter.
8. Establish циферблатный the gauge.
9. Establish an arrow of the gauge on 2 mm, then establish the pump piston before position ВМТ, rotating a pump pulley.

10. Null the gauge. Slowly turn a back asterisk of the pump counter-clockwise while the gauge will not show 0,42 mm (engine AVR) or 0,32 mm (engine AAT). This preliminary value.
11. Check up, that mark ВМТ in a flywheel / a leading disk has been combined with an aperture in a transmission casing. Keeping an asterisk, twirl a fixing bolt of an asterisk till the demanded moment of an inhaling.
12. Turn a cranked shaft of the engine on two turns and again combine marks in a flywheel / a leading disk and a transmission.
13. Check up, that the gauge showed 0,35±0,02 mm (engine AVR) or 0,25±0,02 mm (engine AAT). Repeat adjustment if it is necessary.
