G290PUM piston pin specification (30mm)

This Zenoah piston pin K574791201 is supplied as a single RC-scale spare designed to match the G290PUM designation listed in the item name. It serves as the axial pivot that secures the piston to the connecting assembly inside scale nitro RC engines, and is intended for use during engine rebuilds, routine maintenance, or when replacing worn components.

Installation notes: confirm piston and circlip groove condition before fitting, orient the pin cleanly through piston and conrod, and verify free rotation without binding after assembly. The part is sold without original packing as indicated in the product title.

Tuning and service role: while this pin does not alter tuning settings on its own, correct fitment and undamaged surfaces help preserve piston alignment and consistent performance during tuning or race preparation for scale nitro RC models.

Will this pin improve durability compared to a worn original?

Replacing a worn or scored pin restores correct piston alignment and can prevent accelerated wear, but longevity still depends on installation quality and engine maintenance routines.

How should I inspect the pin and piston surfaces?

Look for scoring, burrs, and groove damage on the piston bore and pin surface; any imperfections should be addressed before refitting to avoid premature wear.

Does the part come with packaging or extras?

The listing notes the pin is supplied without original packing, so expect the single spare only and prepare circlips or other small items separately if required.
