Repair and car operation

Removal, major maintenance and installation of a forward power shaft

This procedure is applicable only to 4WD models.

Removal (the left or external right power shaft)

PERFORMANCE ORDER

Remove assembly of a nave of a forward wheel with the bearing (The section Removal, service and installation of a nave and bearings (a forward wheel)). Remove a board of the disk brake mechanism.

Remove a board of the disk brake mechanism.

Holding a power shaft parallel to a bridge axis, take out it from a bridge sleeve. Try not to damage thus the epiploon of a shaft located on the internal end of a sleeve where the shaft the end equipped with shlitsa enters into differential.

After removal of assembly of a nave the power shaft can be taken from a bridge sleeve, trying to hold it coaxially to the last.

Major maintenance

Odnosharnirny kardanny knot

PERFORMANCE ORDER

Follow indications of the Section Replacement of kardanny hinges, but pay attention that lock rings are established in ears of the holder of a crosspiece and drowned in flutes of covers of bearings. Rings are taken by a poddevaniye by their screw-driver.

Components of assembly of the kardanny hinge of a forward power shaft.

To Vytolknita lock rings from flutes in bearings of the kardanny hinge by means of a small screw-driver.

Hinges of equal angular speeds (CV)

CV JOINTS components of double compensation (CV hinge)

The external CV hinge of a forward power shaft is not subject to repair - in case of wear or damage replacement of all assembly is made. However, the hinge can and should be disassembled, cleaned and filled by fresh greasing in case of damage of a protective cover.

PERFORMANCE ORDER

Cut off both bandages of fastening of a protective cover of the hinge, remove and throw out them. Shift a cover back on a shaft.
Clamp a power shaft in a vice. Between sponges of a vice and shaft in order to avoid damage of the last the rags should be laid. By means of a hammer and the brass drift established on an internal holder beat out the hinge from a shaft.

Bring down CV hinge assembly from a power shaft by means of a hammer and a brass drift (do not allow assembly falling!).

Take a power shaft from a vice. Clamp in a vice hinge assembly (a pin down). Again take care of protection of a surface of a pin against damage by sponges of a vice. Knock on an internal holder with a brass drift, having inclined it enough for a possibility of extraction of a ball of the bearing. Repeat procedure while all balls will not be taken. For extraction from a separator of the "become attached" balls use a screw-driver.

Incline an internal holder, having provided possibility of extraction of the first ball - use a brass drift.

In case of need take the "become attached" balls by means of a screw-driver.

After extraction of all balls incline assembly of an internal holder with a separator under 90 °, achieve combination of windows of a separator with acting platforms of an external holder (the hinge case) and take assembly from an external holder.

Incline assembly of an internal holder with a separator on 90 °, then achieve combination of windows of a separator with platforms on internal walls of the case of the hinge, turn and take assembly from the case.

Pass one of ledges of an internal holder in a window of a separator and, having turned, take a holder from a separator.

Pass one of ledges of an internal holder in a separator window, then turn a holder and take it from a separator.

Wash out all components in solvent and dry them by means of the compressed air (in the presence of access to a source of that). Check a separator and holders on existence of cavities, scratches, cracks and other signs of damage and wear. Existence of zapolirovanny sites to shine is admissible and does not render influence on operation of the CV hinge.

Check ledges and deepenings of an internal holder of the hinge on existence of cavities and scratches.

Examine on existence of cracks, cavities and scratches a separator (existence of zapolirovanny places is admissible and does not render negative impact on operation of the CV hinge).

Insert an internal holder into a separator, operating as it should be, the return described in item 9.
Establish separator assembly with an internal holder in an external holder of the hinge (act as it should be, the return offered in the item 8). The separator should be established in the hinge case by the party of smaller diameter outside, and the lock flute of an internal holder should appear turned in the hinge.
Insert balls into separator windows.

Having achieved combination of windows of a separator with flutes under installation of balls in internal and external holders, incline a separator with an internal holder, serially inserting into them balls.

Fill CV hinge assembly by greasing, having squeezed out in its internal opening equipped with shlitsa, a half of contents enclosed to a remnabor for (CV hinges and their covers) capacities. Knock down greasing in the bearing, having filled wooden whetstone in the opening equipped with shlitsa and having entered it against the stop into a hinge bottom. Repeat procedure, achieving high-quality stuffing of the hinge (the second half of contents of capacity leave for stuffing in a hinge cover).

Fill the hinge greasing through the opening equipped with shlitsa in an internal holder; задавливайте greasing in the hinge by means of wooden whetstone corresponding diameter, entering the last against the stop into a hinge bottom.

Wrap up the part of a power shaft equipped with shlitsa an insulating tape in order to avoid damage of a protective cover of the hinge. Establish smaller diameter a bandage of fastening of a cover in a flute on smaller diameter to the cover party, then pull a cover on a power shaft. Remove an insulating tape and squeeze out the rest of greasing enclosed to a remnabor in a cover.
Establish on a shaft replaceable lock and remote rings.
Put on a shaft the CV hinge so that the internal holder made contact with an internal lock ring.
Establish in the flute on a cover a fixing bandage of bigger diameter and pull a cover on an external holder (case) of the hinge.
Tighten bandages.

Installation

Installation make upside-down. If the intermediate shaft of a two-level power shaft acted in film, establish on a differential cover new laying and fill in in differential oil of a demanded grade (Head of Control and routine maintenance).
