Removal and installation карданного a shaft

Two various executions карданных a shaft are established: propeller a shaft, two-piece with the central bearing and propeller a shaft having two central bearings and one additional hinge of equal angular speeds. Pay attention to distinction at removal.

 REMOVAL

Operation of lifting and car installation on supports is connected with danger! Therefore before operation carrying out familiarise with Razdelom Poddomkrachivanie and towage

1 Lift and establish the car on supports. Remove release system, address to Section Removal and installation of system of release.

2 Turn away bolts of fastening and remove heat-shielding screens-1 and-2 from the bottom.

3 Turn away bolts of fastening and disconnect elastic муфту from a check point (an arrow on an illustration). Keep thus propeller a shaft a tape key from роворачивания.

4 Turn away bolts of fastening and disconnect propeller a shaft from a reducer of the back bridge (an arrow on an illustration). Attention: to establish propeller a shaft in former position mark a paint mutual position of flanges карданного a shaft and a reducer.

5 Oslabte on some turns a carving ring (an arrow on an illustration) on a sliding element by means of the big wrench. If such key available is not present, loosen the carving a ring an alligator wrench.

Bolts - And - fastenings of the central bearing yet do not weaken.

6 Wring out a flange карданного a shaft a screw-driver from a reducer of the back bridge. Thus propeller the shaft moves at a sliding element (the marksman on an illustration).

7 Oslabte fastening bolts - And - the central bearing, address to an illustration.

Thus keep propeller a shaft that it has not fallen. Do not drop a shaft in hinges. In particular, at the hinge of equal angular speeds the shaft can crumple a rubber cover.

8 Kardannyj a shaft consisting of three parts: Similarly turn away the second carving ring at the central bearing. Wring out a forward flange карданного a shaft back, thus propeller the shaft moves.
9 Kardannyj a shaft consisting of three parts: Turn away bolts of fastening of the second central bearing to the bottom.

If there are washers of bolts of fastening, it is necessary to put them at assemblage on former places.

10 incline downwards propeller a shaft at the central bearing a little and take out from an aligning pin on a check point.

Protect the hinge of equal angular speeds карданного a shaft a cover or a polyethylene package from pollution.


 INSTALLATION

The kardannyj shaft отбалансирован also should be replaced only in the complete set. The worn out shaft are replaced.

In the presence of vibration and the noise going from карданного of a shaft, it it is necessary отбалансировать on HUNDRED. Besides, it is necessary to find out, whether hinges are serviceable. There are HUNDRED which specialise on repair карданных shaft.

11 Replace elastic муфту if it is deformed or has a time. For this purpose turn away fastening bolts (arrows on an illustration). New муфту insert so that arrows on a circle showed towards corresponding levers of a flange.

12 Before installation visually check up aligning element-4 карданных shaft. Grease aligning element with greasing “MOLYKOTE LONGTHERM 2 PLUS” or “OPTIMOL OLISTAMOLY 2”. The damaged element replace with HUNDRED.

13 Insert propeller a shaft at first in front into aligning element and fix bolts, without tightening.
14 Put on propeller a shaft with the extended hinge a flange of a reducer of the back bridge.
15 Slightly tighten a carving ring at a sliding element карданного a shaft the moment 10 Nm.
16 In regular intervals tighten fastening nuts карданного a shaft to a reducer, the efforts resulted in Specifications. Apply new self-stopped nuts.
17 Tighten new self-stopped nuts propeller a shaft to a check point flange. The inhaling moment depends on a class of durability of bolts which is beaten out on a head (address to Specifications).
18 Fix the central bearing to the bottom the moment 20 Nm.
19 Kardannyj a shaft consisting of three parts: Fix the second central bearing on the bottom the moment 20 Nm. A carving ring tighten the moment 10 Nm.
20 Fix the heat-shielding screen of system of release. Establish release system, address to Section Removal and installation of system of release.
