Piston pin Kyosho 74031-06 for KE21SP engine upkeep

The Kyosho 74031-06 piston pin is specified for the KE21SP engine to provide a secure joint between piston and connecting rod. It plays a fundamental role in maintaining piston stability and overall engine reliability during service intervals.

Function and when to replace

A correctly matched piston pin reduces unwanted movement and wear inside the top end. The Kyosho 74031-06 ensures proper alignment in KE21SP rebuilds, helping the engine retain consistent power delivery and durability through routine maintenance.

Is the piston pin interchangeable with older parts?

Interchangeability depends on the specific engine variant. The Kyosho 74031-06 is intended for the KE21SP; check dimensions and clearances before fitting into other or older models.

What maintenance stops premature pin failure?

Keep the small end and piston bore clean, use correct assembly technique, and inspect for scoring or play. Addressing combustion or lubrication issues that cause excess loading will also extend pin life.

Do I need special retainers when fitting?

Use the correct circlips or retainers specified for the KE21SP assembly. Secure retaining parts properly to avoid pin movement and potential damage to the piston or rod.
