Renault Clio III (2005-2013) Service Manual / Panelwork / Centre Lower Structure

Centre floor front side cross member: General description

IMPORTANT

Use a repair bench to ensure the positioning of the points and the geometry of the axle assemblies.

Note: The information contained in the following describes the general repair procedure for all vehicles having the same design for this part.

Note: For a detailed description of a particular connection, see MR 400.

I - DESIGN OF THE STRUCTURAL COMPONENT

This is a basic part; it only fulfils the function of a centre floor front side cross member.

II - AREA TO BE CUT FOR PARTIAL REPLACEMENT

The line (1) in the drawing shows the area in which it is possible to carry out a partial replacement.

III - ASSEMBLY METHOD FOR A PARTIAL REPLACEMENT

Only the connections which are specific to the partial replacement by cutting are indicated.

WARNING

If the mating faces of the parts to be welded are not accessible, make EGW plug welds to replace the original resistance welds (see MR 400).

If there are other issues regarding access to mating faces, the various replacement options are described in the basic instructions for structural bodywork repair (see MR 400).

Line (3) on the drawing shows a butt weld by continuous EGW welding.

Centre floor front side cross member: Description

The options for replacing this part are as follows:

• partial replacement of side section,
• complete replacement.

IMPORTANT

For complete replacement, the straightening bench must be used.

I - COMPOSITION OF THE SPARE PART

II - PART FITTED

1 - Partial replacement of side section

WARNING

The correct position of this cut must be observed, as it is determined according to the cut of the internal reinforcements or the acoustic inserts.

2 - Complete replacement

IMPORTANT

For welded connections in three thicknesses, the spot welds on the part replaced should be made in the same place as for the original joint to retain its mechanical properties.

WARNING

If the spot welds cannot be made as they were originally using an electrical spot welding machine, they should be replaced with plug welds after holes have been drilled in the first panel.

Centre floor, side section: General description

WARNING

The information contained in the following describes the general repair procedure for all vehicles having the same design for this part.

These special notes will be specified if applicable in other parts of this subsection dealing with the part.

Note: For a detailed description of a particular connection, (see MR 400).

I - DESIGN OF THE STRUCTURAL COMPONENT

The special feature of this type of part is that it combines the functions of the centre floor side section and the sill panel closure panel and it is made of two different kinds of panel of different thicknesses assembled by laser butt welding.

II - AREA TO BE CUT FOR PARTIAL REPLACEMENT

These cutting lines show the area in which it is possible to carry out a partial replacement of the centre floor side section.

Cut 1, 2 and 3:

• cut (1) affects the partial replacement of the centre floor side section,
• cuts (1) and (2) affect the partial replacement of the rear section of the centre floor side section
• cuts (1) and (3) affect the partial replacement of the front section of the centre floor side section.

III - ASSEMBLY METHOD FOR A PARTIAL REPLACEMENT

Only the connections which are specific to the partial replacement by cutting are indicated.

WARNING

If the spot welds cannot be made as they were originally using an electrical spot welding machine, they should be replaced with plug welds after holes have been drilled in the first panel.

If there are other issues regarding access to mating faces, the various replacement options are described in the basic instructions for structural bodywork repair (see MR 400, 40A, General Information).

Line (1) on the diagram shows partial replacement and a weld by joggling with plug welds at regular intervals.

Lines (1) and (2) on the diagram show the partial rear replacement and a weld by joggling with plug welds at regular intervals.

Lines (1) and (2) on the diagram show the partial front replacement and a weld by joggling with plug welds at regular intervals.
