RC-scale Replacement Piston K116041110 for EHT752S eHT602D by Zenoah  [K116041110]

Hobby engine piston replacement guide

This Zenoah K116041110 piston is intended as an RC-scale replacement for hedge trimmer model engines labeled EHT752S and eHT602D. It is supplied as a single pcs item for hobby use and not for standard full-size equipment.

Install this piston when the existing unit shows wear, scoring, or damage. Always confirm the K116041110 identifier and visually compare the piston to your original and the engine plate before proceeding. The listing covers the piston alone; you will need to source rings, seals, and any necessary hardware separately.

Installation notes: follow accepted small-scale rebuild practices — clean the cylinder thoroughly, inspect the bore, lubricate moving parts during assembly, and torque fasteners to the engine maker's specifications. For engines modified for greater output, recheck piston-to-cylinder clearance and ring seating after the initial break-in period to avoid premature wear.
