- using a knock-out and a hammer, beat the inner joint race
from shaft 4;
- after removing the thrust ring, move the shroud from the
shaft;
- wash the inner cavities of the joint housings and other com-
ponents.
The most difficult and crucial are the operations on disman-
tling and reassembling the outer joint, the components of which
are shown on fig. 3-83. The high quality of dismantling-reassem-
bly works is provided with observance of below instructions.
Mark with paint the mutual arrangement of the race, cage and
the joint housing. Fix the outer joint in vice, as shown on fig. 3-84.
Incline the race and cage so that one ball will go out from the
groove in the case of the joint as far as possible. Using a screw-
driver made of soft metal, push the ball out from the cage. Then
turn all components so that the next ball will occupy the same
position, and take it out from the cage. Using the above proce-
dure, take out other balls. The sequence of removing the balls
from the cage can be different - every other ball.
Slight tapping on the cage or race with a tool made of soft
material is allowed. No excessive effort when turning the cage is
admissible, as the balls may be blocked what will complicate the
further dismantle.
Place the cage/race unit so that the elongated apertures of
the cage are situated against the ledges of the joint case (see fig.
3-85) and take out the cage in assembly with the race.
Take the race out from the cage, to do that, place one of the
race ledges in the elongated opening of the cage (see fig. 3-86)
and then roll out the race in the direction of the straight edge of
the aperture. Wash all components and blow with compressed
air.
The reassembly of the outer joint
is carried out in reverse
sequence, paying attention to the following:
- grease all components with òêìë-4 before reassembly;
- when refitting the cage/race assembly in the joint casing,
ensure the matching of labels made before dismantle, the race
should be fitted with the ring groove (for the thrust ring) facing the
shaft;
- when refitting the balls in the cage, incline the race approx-
imately by an angle twice bigger, than the cage;
- fill the joint with 60 cm
3
of òêìë-4;
- before striking the shaft 4 (see fig. 3-82) to connect it with
the inner race 11, it is necessary to fit a new circlip 12 strictly in
the centre, and then sharply strike downward on the shaft end;
the circlip will compress and slip through the race spline opening;
- use tool 67.7853.9533 to press-fit the sealing ring in the joint
housing.
After reassembly, the race might be blocking at shaft rolling,
when the ball does not rotate. This does not indicate a poor-qual-
ity assembly, as such blocking will not appear at the joint rotation
during operation.
Using the above mentioned procedure, dismantle completely
the inner joint. The race should be taken out in the direction of the
larger diameter of the cage.
The reassembly of the inner joint is carried out in reverse
sequence. It is necessary to match the labels made before dis-
mantle. The elongated cone part of the cage should be facing
shaft 4. When reassembling, fill 150 cm
3
of òêìë-4 into the joint.
Use tool 67.7853.9537 to refit the joints protective covers.
If there are no knocks and vibrations, the shrouds are in good
condition, the dismantle of the front wheels drive is not recom-
mended.
