Piston pin for G290PUM - 30mm fitment

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.

Can replacing this pin affect engine tuning?

The pin itself does not change jetting or timing, but ensuring correct alignment and smooth rotation supports stable combustion behavior and consistent tuning results.

Recommended checks during break-in after fitting?

After fitting, run a short, controlled break-in session, monitor temperature and piston movement, and recheck circlip security and rotation to confirm correct seating.

Should I replace the pin at the same time as other parts?

Many users replace the pin when servicing the piston or rod; replacing related wear items together reduces the chance of repeat work and helps maintain consistent engine behavior.
