Hitachi 6698368 Spare Part - PISTON

Hitachi 669‑8368 — genuine Hitachi piston for small 24cc handheld blowers. This direct replacement piston is listed as part number 669‑8368 on Hitachi RB24EAP parts diagrams and is the component that transfers combustion force to the crankshaft; use it when the piston is scored, worn or the engine has poor compression.

Fits common Hitachi/Tanaka/Metabo HPT blower models such as RB24EAP and is referenced across CG24EASP / CG24EASPSL and TRB24EAP model compatibility lists, so it’s a match for those engines when the original piston has failed.

Install notes and related parts: the piston works with piston ring 669‑8404, piston pin 668‑4591 and circlip 668‑4590 as shown in the parts diagram—confirm those items when rebuilding the cylinder assembly. The part is precision machined to original Hitachi specifications to restore proper compression and starting performance.

This is a genuine Hitachi spare designed specifically for these blower engines — a compact, direct-fit repair item to get your machine back to work with the correct internal components for reliable operation. Use this part when ordering other small engine parts or parts for power tools to ensure full rebuild compatibility.
