Peugeot 307 CC 8484F6 sunroof pump housing

Description

Electric sunroof hydraulic pump sound insulation kit for Peugeot 307 CC cars

Part description

This used part serves as a cover / soundproofing kit for the hydraulic pump of the electric roof retracting system. It is designed for the Peugeot 307 CC and its purpose is to reduce noise and vibrations transmitted from the pump to the body and surrounding parts. If the original insulation is damaged, missing or soaked, the operation of the roof can be significantly noisier and the entire set can withstand vibrations during operation.

The part is suitable for mechanics and home repairs wherever the noise of the roof mechanism is solved or the replacement of damaged casing/insulation parts around the pump.

Installation recommendations

Generally/typically for changing the cover and soundproofing of the roof pump system, the exact mounting and access depends on the specific car variant and the installation. Consider the procedure below as a practical guide for this type of part.

1) Before assembly

• Compare the new and original piece: the shape of the package, the breakdown of the insulation, the attachment points and any grommets/holes.
• Check the condition of the used insulation: cracks, hardening, disintegration of the material, dents, liquid absorption or odor after overheating.
• Verify that the part matches the marking 8484F6.

2) Necessary tools and materials

• Basic set of hand tools (screwdrivers, ratchet with attachments according to the used connecting material)
• Plastic pry bar for removing upholstery/covers (to limit plastic damage)
• Cleaning agents for degreasing and rags (for cleaning contact surfaces)
• Flashlight and possibly small pliers for clips/handles

3) Step-by-step assembly procedure

1. Secure the vehicle against movement and prepare a work area for safe access to the roof system.
2. Disconnect the battery (for electrical systems, this is a recommended safety step to prevent accidental switching).
3. Remove the covers/linings that prevent access to the hydraulic pump and its insulation (careful not to break the mounts).
4. Document the original condition (photo): routing of cables/hoses in the vicinity, position of packaging and method of attachment.
5. Remove the original packaging/insulation elements. If they are attached with clips or screws, put the fasteners aside.
6. Clean the surroundings and the contact areas so that the new insulation fits properly and does not pinch anywhere.
7. Place the cover and insulation parts in the same direction and orientation as the original piece.
8. Check that the insulation doesn’t interfere with moving parts and doesn’t press on nearby wiring.
9. Secure the package back in the original way (clips/handles/screws according to design).
10. Reinstall all the removed covers/trimmings, making sure the clips are properly seated.
11. Connect the battery.
12. Perform a functional test of lowering the roof and notice the change in noise and possible vibrations.
• 4) Post-assembly checks and test drive/function verification
  • Verify that nothing rubs and the insulation does not move anywhere while the system is running.
  • Listen to see if the pump’s noise has changed for the worse (which may indicate a bad seal).
  • After several cycles, visually check the fit and fit of the insulation again.

  5) The most common assembly mistakes + how to avoid them

  • Wrong packaging/insulation orientation → before disassembly, take photo documentation and compare the shape and passages.
  • Insulation pinching under the cover → check that the insulation fits in the designated places before final tightening.
  • Damage to trim clips → use a plastic pry bar and work without violence; replace defective handles immediately.
  • Installation without disconnecting the battery → there is a risk of unintentional switching and subsequent complications with electrical circuits.

  Reasons why the part is damaged

  • Aging of the material (hardening, embrittlement, breakdown of foam/insulation due to time and temperature cycles).
  • Vibration and mechanical friction – the insulation can penetrate the surrounding parts if it is not properly seated.
  • Moisture and pollution – soaking with water or dirt reduces the damping effectiveness and accelerates degradation.
  • Incompetent intervention during repair – damage when disassembling covers, breakage of attachment or incorrect assembly.
