Removal and installation ТНВД

Check of installation of phases of injection ТНВД on diesel engines is made in the static way. For an estimation of size of lifting of the pump it is required циферблатный a measuring instrument плунжерного type. Installation of phases is defined by distance between from label ВМТ on a flywheel to the fixed point on the engine which measurement should be entrusted to the qualified experts of car-care centre.

REMOVAL

 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery.
2. Remove an inlet sleeve of an air cleaner (see Has undressed Removal and installation of assemblage of an air cleaner and components of an inlet path).
3. In view of the extremely limited access to the pump it will be reasonable to remove a radiator.
4. Operating according to the instructions resulted in the Head Repair двигателявыполните following actions:
a) Uncover a camshaft an external cover of a belt of drive ГРМ;
b) Result the engine in position ВМТ;
c) Throw off a gear belt from gear pulleys of a camshaft and ТНВД.
5. Now it is necessary to remove a cogwheel from shaft ТНВД. In process отпускания fixture the cogwheel should be blocked from проворачивания by means of approaching the adaptation which can be easily made of make-shifts (see Has undressed Removal and installation of a belt of drive ГРМ and its covers).

6. Release three fixing bolts and remove a cogwheel from a pump flange.

At all do not weaken the central nut of a cogwheel as it can lead to infringement of base installations of phases of injection.

7. Preliminary having marked, disconnect from the pump hoses of giving and fuel return also disconnect from the returnable union a control hose.
8. By means of two nut key (probably it is necessary to take advantage of a cutting key with a cutting head) ослабьте штуцерные connections of rigid fuel tubes on back part ТНВД and each of atomizers. Remove assemblage of tubes from the engine.

Prepare for gathering of spilt fuel - enclose under distributed штуцерные connections rags. Try not to admit at all deformation of rigid fuel tubes.

9. In order to avoid hit of a dirt in the power supply system at once закупорьте the open ends of fuel tubes and unions. Take advantage of the finger cut off from a rubber glove...

..., Or muffle unions by means of the hollow bolt turned out from it who have been preliminary densely put in a piece of a hose approaching on diameter.

10. Disconnect a vacuum tube from a drive of the device of increase of turns of idling on wall ТНВД.

11. Disconnect a cable of an accelerator from arm ТНВД (see Has undressed Removal, installation and adjustment of a cable of an accelerator).

12. Preliminary having marked disconnect electroconducting from following components:

a) the Gauge-switch of pressure of oil at the left end face of a head of cylinders;
b) the Gauge-switch of temperature/pressure of oil on a basic arm of the fuel filter;
c) Two established in an arm on the left wall of the block of cylinders of sockets;
d) the Gauge of temperature of a cooling liquid on a knee охладительного a path in a forward part of a head of cylinders.

13. Before removal ТНВД mark position of fixing bolts in oval apertures - at assemblage the pump should is established strictly in former position in order to avoid infringement of base installations of phases of injection.
14. Turn out a back fixing bolt and three bolts from the forward party of the pump (accompanying illustrations see). Make sure that nothing remains connected to ТНВД and take the pump from an impellent compartment.

INSTALLATION

 PERFORMANCE ORDER

1. Establish ТНВД on the regular place on the engine, tighten fixture with demanded effort.

Fixing apertures of the pump have the oval form that allows to correct pump position on the engine. At installation of the new pump bolts should be established at first in the central part of apertures for the purpose of maintenance of the maximum range of adjustment. The old pump is established strictly in former position according to the marks put in the course of dismantle.

2. Make initial filling of the pump pure diesel fuelм through a funnel serially inserted into unions of giving and return of fuel (for gathering of spilt fuel impose unions with rags).
3. Connect fuel tubes to atomizers and the pump. With demanded effort tighten штуцерные connections by means of two wrenches.
4. Connect to ТНВД tubes of giving and fuel return (do not forget to replace sealing washers). Tighten hollow bolts штуцерных connections with demanded effort.
5. According to the marks put in the course of dismantle connect all disconnected electroconducting.
6. Connect a vacuum tube to the valve of the device of increase of turns of idling.
7. Connect and adjust an accelerator cable (the Section ventilation System картера - the general information see).
8. Establish into place a cogwheel of the pump and fix its three bolts - pass bolts in oval apertures and tighten them, while only by hand.
9. Block a cogwheel from проворачивания, having passed a metal core through a centering aperture in drilling in a pump nave. Люфт the blocked wheel should be minimum.
10. Establish a gear belt of drive ГРМ and adjust its tension (see Has undressed Removal, check of a condition and installation of a forward cover, a chain and asterisks of drive ГРМ).
11. Now it is necessary to check up installation/adjustment of phases of injection ТНВД in the conditions of a car-care centre workshop. At installation new ТНВД it is necessary to connect also to it иммобилизатор anticreeping system.
12. Check up idling turns, in case of need make corresponding updating. Then check up installation of the maximum turns of the engine (the Section release System - the general information and replacement of components see) and turns of fast idling (see Has undressed the Katalitichesky converter - the general information and safety measures).
13. The further assemblage is made in an order, the return to a dismantle order.
