5.14. Restoring the covering

exhaust in the engine compartment).
Noise protection : The noise protection is provided using a sound deadening sleeve during reworking requiring simple mechanical protection (E.g. : Passenger compartment, Tailgate).

5.14. Restoring the covering

In the case of changes to the routing, a distance of 10 mm minimum must be guaranteed between the harness and its surroundings. A positioning device is compulsory to guarantee the positioning and orientation.

Taped strands : Place the repaired part flush against the body of the harness and tape the whole using adhesive tape.

Sleeved strands : Place the repaired part flush against the body of the harness then put the sleeving back in place.

Closed sleeves : Avoid cutting the closed sleeves in order to permit passage of the wire, otherwise place the repaired wire on top with appropriate covering.

Open sleeves : It is compulsory to tape the openings after work.

5.15. Method for repairing the earth points

N.B. : In all cases, check the condition of the earth terminal contact/support/nut or bolt surface and clean it.

Several solutions are recommended.

Soldered square nut with broken self-tapping bolt or the thread of which is damaged :

• If the bolt can be extracted, remove it, drill and tap to M8 using a new M8 bolt then apply a tightening torque of 17 Nm ± 3 Nm
• If there is another earth nut nearby, extend the earth wire to reach this earth point, taking care to create a drip channel loop, Apply a tightening torque of 12 Nm ± 2 Nm

Stud which is badly soldered (TUCKER stud), broken or the thread of which is damaged :

• If the stud soldering has failed, re-solder the old stud by brazing
• If the thread is damaged or the bolt is broken, solder a new stud by brazing

In the 2 cases of soldering, apply the method below :

• Place a fire extinguisher near the work area
• Strip the location at which the pin is to be soldered
• Rotary sand the soldering location
• Solder the stud or the pin using the gun provided for this purpose
• Apply anticorrosion protection
• Put the removed components back in place

Soldered square nut with slackened self-tapping bolt :

• If the M6X100 self-tapping bolt is simply slack, retighten the bolt applying a tightening torque of 12 Nm ± 2 Nm
• If the bolt has to be removed, fit a new M6X100 self-tapping bolt, engage it manually in the existing thread (take care not to create a new thread) then apply a tightening torque of 12 Nm ± 2 Nm

Earth on the gearbox slackened : If the bolt M8x125 is simply slack, retighten by applying a tightening torque of 17 Nm ± 3 Nm.

6. Specificities : Hybrid vehicles

The harnesses of the 200 V network in hybrid vehicles can be repaired, with the exception of the shielded cable; Replacement of the shielded cable is imperative if there is any damage to the cable or its connections.

ESSENTIAL : For the harnesses of the 200 V network, on hybrid vehicles (low voltage range of 50 V to 1000 V), the personnel must have the authorisation according to the type of operation of the publication UTE C 18-550.

If the reworking is carried out by a third party, a contract must be drawn up for the work between the supplier and the company that it employs, before the work is carried out.
