Piston wrist pin snap ring for Zenoah engines

This Zenoah K126041320 snap ring is a dedicated RC-scale spare for retaining the piston wrist pin on select Zenoah engine families. It serves as a direct replacement component intended to secure the wrist pin against axial movement during normal model engine operation.

The part fits the listed models G200, G230, G231, G240, G260, G270 and G290, and is supplied without extra packing. Use this ring when inspecting piston and connecting rod wear, and replace any deformed or fatigued rings to maintain correct piston alignment and reliable rotation under load.

Installation notes: visually inspect the groove on the piston wrist pin and confirm the snap ring seats fully in the groove. Handle the ring carefully during removal and installation to avoid nicking the wrist pin or piston; replace the ring if it shows visible distortion.
