Peugeot 308: Replacement : Outer sill section under door (floor)

ESSENTIAL : Before any operation on the structure of a vehicle fitted with a traction battery, the vehicle must be disconnected electrical supply.

ESSENTIAL : Observe the safety and cleanliness recommendations .

ESSENTIAL : Observe the precautions to be taken for the pyrotechnic components .

ESSENTIAL : All personnel carrying out work on a vehicle fitted with traction batteries must have received specific electric vehicle training and be authorised to work on these vehicles (observe the regulations in force in the respective country).

CAUTION : All of the stripped surfaces must be protected by means of the approved electrolytic rezincing process .

CAUTION : The number of spot welds or weld beads required for assembling a new component must be identical to the number of spot welds or weld beads attaching the original component.

1. Information

Types of spot welds or beads using the electric arc process :

• MIG braze welding with cupro-aluminium filler used with an inert gas
• MAG welding with steel filler metal and active gas

Designation of the high strength panels :

• High strength (HSS) : High strength steel
• Very high strength (VHSS) : Very high strength steel
• Ultra high strength (UHSS) : Ultra high strength steel

N.B. : Use the products recommended by the manufacturer .

2. Tooling

Workshop equipment :

• Swan’s neck drill for cutting out electric spot welds
• Hot air blower

Tool	Reference	Description
	[1366-ZZ]	Toolkit for testing electric spot welds
	[1366]	Samples for testing electric spot welds
	[1126]	Set of drill bits for removing spot welds
	[FEIN-400E]	"FEIN-400E" electric knife kit-"C1" electric knife-"C2" "FEIN" offset hub saw blade-"C3" Blade no. 103

3. Preliminary operations

ESSENTIAL : Deactivate the pyrotechnic systems .

CAUTION : Perform the operations that are required prior to a disconnection of the ancillaries battery .

CAUTION : In the case of a vehicle with 2 batteries, carry out the specific operations for disconnecting and reconnecting the ancillaries batteries.

Disconnect the ancillaries battery or batteries.

CAUTION : Either remove or protect those components which are in the repair zone and risk being damaged by the heat or the dust.

Remove :

• The front door
• The front door aperture seal
• The interior trims
• The body sill plugs

Release the electrical harnesses.

4. Location of the replacement part

Identification	Description
(1)	Outer sill section under door (floor)

5. Identification of the replacement part

5.1. Composition : Outer sill section under door

Identification	Description	Thickness	Nature/classification
(1)	Outer sill section under door	0,64 mm	Mild steel

N.B. : The outer sill section under the front door is extracted from the outer sill .

5.2. Identification of the parts adjacent to the replacement part

Identification	Description	Thickness	Nature/classification
(2)	Front interior sill	1,35 mm	Very high strength (VHSS)
(3)	Central interior sill	1,35 mm	Very high strength (VHSS)
(4)	Side member strengthener	1,15 mm	Very high strength (VHSS)
(5)	Front pillar strengthener	1,25 mm	Ultra high strength (UHSS)

6. Replacement part preparation

CAUTION : When cleaning the mating edges, use scouring wheels only to avoid damaging the anticorrosion protection.

"B" = 400 mm.

N.B. : The cutting line of the outer sill below-door section must not be less than the dimension "B".

Mark (at "a", "b") in the cutting zones "A", "C", then cut .

The cutting lines "a" and "b" are shown as a guide and may change for different examples of replacement of the under-door section of the outer sill panel.

Prepare the mating edges and protect them using a weldable primer (index "C7").

N.B. : Apply the weldable primer on the internal faces of the panels to be welded.

7. Cutting of the part on the body

Mark (at "c", "d") in the cutting zones "D", "E", then cut .

The cutting lines "c" and "d" are shown as a guide and may change for different examples of replacement of the under-door section of the outer sill panel.

Cut out the spot welds .

Remove the outer sill section underneath the door (floor).

8. Cleaning and preparation of the body

Prepare the mating edges and protect them using a weldable primer (index "C7").

N.B. : Apply the weldable primer on the internal faces of the panels to be welded.

9. Adjustment

Position :

• The outer sill section under door (floor)
• The components for adjusting

Check the fits and clearances .

Clamp the part into position.

10. Welding

CAUTION : Set the welding station.

Setting of the welding station :

• Electric spot weld testing ; Using the tool [1366-ZZ]
• Samples for testing electric spot welds ; Using the tool [1366]

CAUTION : The number of spot welds or weld beads required for assembling a new component must be identical to the number of spot welds or weld beads attaching the original component.

Weld with electric spot welds.

Weld with MAG beads.

Grind the MAG weld beads.

11. Sealing protection

Apply :

• A layer of etch primer to the zones exposed
• Sealing mastic (index "A1")
• Anti-chip protection (index "C4")

Painting, then spraying of the index "C5" product into the hollow sections in the repair zone.

12. Additional operations

Refit the electrical harnesses and reinstall all removed components.

13. Reinitialisation

ESSENTIAL : Reactivate the pyrotechnic systems .

Restore the voltage supply to the vehicle.

CAUTION : Perform the operations that are required after reconnecting the ancillaries battery .

CAUTION : In the case of a vehicle with 2 batteries, carry out the specific operations for disconnecting and reconnecting the ancillaries batteries.

Reconnect the ancillaries battery or batteries.
