Description

Alternator holder 1.4 HDI 16V for CITROEN PEUGEOT cars

Part description

This alternator holder is designed for the 1.4 HDI 16V engine in Citroën/Peugeot cars. It is used to firmly hold the alternator and to maintain its correct position, which is essential for the trouble-free operation of engine accessories and stable charging.

If you are looking for a part by number, take into account in particular the designations 9646424380 and 5706G3 – they are often the fastest way to identify holders in practice and in the catalog.

Installation recommendations

Typically for the alternator bracket, the exact steps may vary depending on the specific engine design and fitment in the vehicle. Below is a practical general procedure for replacing this type of part.

1) Before assembly

• Compare the new and original holder: shape, seating surfaces, number and distribution of holes, threads and any guiding elements.
• Check the bracket for cracks, deformations or squashed seating surfaces.
• Verify compliance according to codes 9646424380 / 5706G3 (if they are listed on the original part).

2) Necessary tools and materials (in general)

• Basic set of gola/ratchet and extensions, open-end wrenches
• Torque wrench (values according to the manufacturer’s service procedure)
• Cleaner for degreasing and rags, or a soft brush for cleaning the contact surfaces
• Suitable lighting, possibly means to ensure access (according to the specific car)

3) Step-by-step assembly procedure

1. Secure the vehicle against movement and allow the engine to cool.
2. Disconnect the battery (for safety when working on the alternator and wiring).
3. Depending on the design of the car, remove the obstructing covers or parts to access the alternator and bracket.
4. Release accessory tension and remove belt (procedure varies by tension type).
5. Disconnect the electrical connectors/lines from the alternator so as not to damage the wiring.
6. Unfasten the alternator and carefully release it from the bracket (just move it away or remove it depending on the space).
7. Dismantle the original alternator holder and check the condition of the threads and the bearing surfaces on the engine.
8. Clean the bearing surfaces and prepare them for assembly (free of dirt and corrosion residues).
9. Put on the alternator holder, seat it without tension and gradually tighten the fastening.
10. Install the alternator back into the bracket, check its correct seating and alignment.
11. Reconnect the alternator electrical connectors/lines and secure the lines against chafing.
12. Put on the belt and adjust/restore the correct tension according to the procedure for the design.
• 4) Post-assembly checks and test drive/function verification
  • Before starting, double-check the tightening, wiring and proper seat of the belt.
  • After starting, observe whether the belt runs smoothly, without throwing or whistling, and whether the alternator behaves without vibrations.
  • After a short ride/operation, visually check the fastening again and any unusual noises.

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

  • Exchanging the holder (similar shape, different fit) – always compare the part and verify the codes.
  • Uncleaned bearing surfaces – stress, misalignment and vibration may occur.
  • Damage to the alternator wiring during handling – route the cables away from sharp edges and secure them properly.
  • Poorly fitted/tensioned belt – check the guide along the grooves and smooth running after starting.

  Reasons why the part is damaged

  • Vibration and long-term stress from the engine and accessories, which gradually weakens the material.
  • Incorrect alignment of the alternator/belt (e.g. after improper installation), which loads the holder off-axis.
  • Excessive or loose fastening – overloading of the holder, squeezing of the contact surfaces or damage to the threads.
  • Corrosion and contamination that worsen the fit and promote cracking in stressed areas.
  • Impact damage when handling in the engine compartment or after a collision.
