Part description

This used car part is intended for Citroën and Peugeot cars with 1.4 HDI and 1.6 HDI engines. This is a crankshaft gear, which is part of the timing mechanism of the engine and ensures the correct transfer of movement within the timings. When searching, the part is also often searched for under the designations 9810698080 and 0805E5.

For this type of part, the exact design of the teeth and the overall condition of the functional surfaces are essential. For mechanics and home repairers alike, it is important that a correctly selected timing pinion helps maintain the precise function of the engine timing and contributes to reliable engine operation.

Installation recommendations

Generally/Typically replacing the crankshaft gear requires care and the exact steps may vary by car model and make.

1) Before assembly

• Check whether the new used gear is dimensionally and structurally identical to the dismantled part.
• Compare the number of teeth, the width of the part, the shape of the central support and the overall condition of the bearing surfaces.
• Check for cracks, deformation, excessive tooth wear or signs of improper disassembly.
• Before assembly, clean the adjacent surfaces and check the condition of the surrounding parts of the distribution mechanism.

2) Necessary tools and materials

• A common set of hand tools
• Preparations for the safe disassembly of covers and related parts
• Cleaning agent for technical parts
• Clean rags or towels
• Protective work equipment

3) Step-by-step assembly procedure

1. Secure the vehicle against movement and prepare a work area.
2. Disconnect the battery if the nature of the intervention and access to the part requires it.
3. Remove the covers and related parts so that the part can be safely accessed.
4. Carefully mark the position of related parts if needed for subsequent assembly.
5. Remove the original crankshaft gear in a manner that does not damage the crankshaft or surrounding components.
6. Check the condition of the bearing surface, grooves and connected mechanical parts.
7. Clean the installation site from dirt, old deposits and metal particles.
8. Place the spare part in the correct position according to the design of the bearing.
9. Reassemble all removed parts in reverse order.
10. Check that the part moves correctly in relation to other parts of the distribution and there is no contact anywhere outside the working surfaces.
11. After assembly is complete, reconnect the battery if it was disconnected.
• 4) Post-assembly checks and test drive/function verification
  • After assembly, verify that all parts are properly seated and secured.
  • Check for unusual sounds from the engine compartment.
  • After starting, observe the smooth running of the engine and possible vibrations.
  • After a short function verification, visually check the mounting area again.

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

  • Replacing a part with a similar type – always compare the designation and design before assembly.
  • Mounting on dirty seating surfaces – dirt can cause the part to sit incorrectly.
  • Damage to the teeth during handling – handle the part with care and do not use unsuitable tools.

  Reasons why the part is damaged

  • Long-term mechanical wear during normal engine operation
  • Incorrect function or wear of connected parts of the distribution system
  • Damage to the teeth during unprofessional disassembly or assembly
  • Pollution, corrosion or intrusion of foreign particles into the distribution area
  • Excessive stress caused by failure of other engine components
