Removal and driveshaft installation

Two various executions of the driveshaft are established: the driveshaft, two-piece with the central bearing and the driveshaft 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 carrying out operation familiarize with Poddomkrachivaniye's Section and towage

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

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

3 Unscrew bolts of fastening and disconnect the elastic coupling from a check point (an arrow on an illustration). Hold thus the driveshaft a tape key from a rovorachivaniye.

4 Unscrew bolts of fastening and disconnect the driveshaft from a reducer of the back bridge (an arrow on an illustration). Attention: To establish the driveshaft in former situation mark paint the mutual provision of flanges of the driveshaft and a reducer.

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

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

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

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

Thus hold the driveshaft that it did not fall. Do not drop a shaft in hinges. In particular, at the hinge of equal angular speeds the shaft can crumple a rubber cover.

8 Driveshaft consisting of three parts: Similarly unscrew the second carving ring at the central bearing. Wring out a forward flange of the driveshaft back, thus the driveshaft moves.
9 Driveshaft consisting of three parts: Unscrew 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 assembly on former places.

10 incline down the driveshaft at the central bearing A little and take out from an aligning pin on a check point.

Protect the hinge of equal angular speeds of the driveshaft a cover or a plastic bag from pollution.


 INSTALLATION

The driveshaft отбалансирован also should be replaced only in a set. Worn-out shaft are replaced.

In the presence of vibration and the noise going from the driveshaft, it it is necessary отбалансировать on HUNDRED. Besides, it is necessary to find out, whether hinges are serviceable. There are HUNDRED which specialize on repair of driveshafts.

11 Replace the elastic coupling if it is deformed or has a time. For this purpose unscrew fastening bolts (arrows on an illustration). The new coupling insert so that shooters on a circle showed towards the corresponding levers of a flange.

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

13 Insert the driveshaft at first in front into aligning element and fix bolts, without tightening.
14 Put on the driveshaft with the extended hinge a flange of a reducer of the back bridge.
15 Slightly tighten a carving ring at a sliding element of the driveshaft the moment of 10 N • m.
16 Evenly tighten nuts of fastening of the driveshaft to a reducer, the efforts given in Specifications. Apply new being self-stopped nuts.
17 Tighten new being self-stopped nuts the driveshaft to a check point flange. The moment of an inhaling 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 of 20 N • m.
19 Driveshaft consisting of three parts: Fix the second central bearing on the bottom the moment of 20 N • m. A carving ring tighten the moment of 10 N • m.
20 Fix the heat-shielding screen of system of release. Establish release system, address to the Section Removal and installation of system of release.
