⚠️ Common Signs of Failure

• A light metallic knock from the top of the engine, clearest at idle and on the overrun
• The knock changing character as the engine warms through
• Pin scored, galled or heat-discoloured where it runs in the small end
• Bright metal particles in the oil or caught on the filter
• Measurable slack between the pin, the small-end bush and the piston bosses

🛠️ Service Notes

• Renew the small-end bush and measure the piston pin bosses at the same time - a new pin in a worn bore will knock again
• Piston pin 20569833 is the other pin listed here, at 1.361 kg and covering 40 TAD and D applications; the two are not alternatives for each other, so order against the engine rather than by name
