5.6. Hydraulic coupling of the fan

GENERAL INFORMATION

4-CYLINDER PETROL ENGINE

1. Nozzle of a rozhkovy wrench
2. Dinamometrichesky wrench
3. A countersupport at a pulley with a flat lock washer
3а. A countersupport at a pulley with the bolts, having an internal shestigrannik
25. Fan
25а. Bolt of 6 x 14, 10 N of m.
26. Sealing ring
26а. Cap nut
33. Pulley
33а. Flat lock washer
And – Untwisting
In – Screwing up

Removal



PERFORMANCE ORDER
1. Turn off a rozhkovy key a cap nut, thus by means of a countersupport clamp a pump pulley for supply of cooling liquid.
Prevention

The nut has the left carving.


2. Extend the hydraulic coupling together with the fan.
3. Unscrew 3 fixing bolts and separate the fan from the coupling.

Installation

PERFORMANCE ORDER
1. Connect the coupling to the fan.
Prevention

The correct assembly position of the fan is defined by means of the welded-on edge.


2. Screw the hydraulic coupling with the moment of 10 N of m.
3. Insert the hydraulic coupling together with the fan and screw with the moment in 40 N of m. For this purpose the dinamometrichesky wrench with a nozzle of a rozhkovy wrench is required.
Prevention

The nut has the left carving.



6-CYLINDER PETROL ENGINE

Removal



PERFORMANCE ORDER
1. Remove a fan casing.
2. Unscrew a bolt (3) on the hydraulic coupling of the fan. Thus hold a pulley from rotation to the opposite side by means of a self-made key on лыске a disk (6).
3. Take the fan together with the hydraulic coupling.

Installation

PERFORMANCE ORDER
1. Thus insert the coupling fan that welded-on number of a detail was ahead from a radiator.
2. Screw the coupling fan with the moment of 45 N of m, thus hold a pulley from rotation to the opposite side.
3. Establish a fan casing.

DIESEL ENGINE IN VOLUME OF 2,0/2,2 L


Removal

PERFORMANCE ORDER
1. Unscrew (And) a cap nut (2а) a wrench (5), thus fix a pulley of the pump of system of liquid cooling by means of a countersupport (9).
Prevention

The nut has the left carving.


2. Take together with the fan (1) hydraulic coupling (2).
3. Unscrew three fixing bolts (3) and separate the fan from the coupling.

Installation

PERFORMANCE ORDER
1. Insert the coupling into the fan of system of cooling. By means of a ledge on a ring of the fan the correct assembly position of the fan is defined. Marking of "VORNE FRONT" specifies in the movement direction.
2. Screw the hydraulic coupling of the fan with the moment of 10 N of m.
3. Insert the coupling into the fan of system of cooling and together screw them on a pump shaft for supply of cooling liquid with the moment of 45 N of m. For this purpose the dinamometrichesky natural by a nozzle of a rozhkovy key 36 is required.
Prevention

The nut has the left carving.



DIESEL ENGINE IN VOLUME OF 2,5 L

Removal



PERFORMANCE ORDER
1. Remove a casing of the fan and lay it over the fan of system of cooling.
2. Unscrew the hydraulic coupling together with the fan of system of cooling, including a bolt with an internal shestigrannik. Thus hold a pulley by means of a countersupport.
3. Extend up the fan (1) together with the coupling (2) and its casing.
4. Unscrew the fan with four bolts (4) from the hydraulic coupling.

Installation

PERFORMANCE ORDER
1. Insert the hydraulic coupling into the fan of system of cooling and screw it with the moment of 10 N of m.
Prevention

Marking of "VORNE FRONT" specifies in the movement direction.


2. Put together the coupling with the fan of system of cooling and a fan casing.
3. Screw the coupling fan with the moment of 45 N of m, thus stop a pulley.
4. Mount and adjust a fan casing.
