Product Description

The ECHO a101000820 is a replacement piston ring designed for use in ECHO two-stroke outdoor power equipment engines. The piston ring seats in the groove of the piston and maintains a seal between the piston and cylinder wall, controlling compression and limiting oil passage into the combustion chamber. This is an OEM-sourced component intended for installation by small-engine technicians and qualified service professionals performing engine rebuilds or top-end repairs on ECHO-branded equipment.

This piston ring is suited for service situations where compression loss, excessive oil consumption, or scoring has been identified during engine diagnosis. Typical applications include top-end engine rebuilds on ECHO handheld and walk-behind outdoor power equipment such as chainsaws, trimmers, blowers, and similar two-stroke units. Installation is performed as part of a piston or cylinder service procedure.

Installation Notes

Installation of this piston ring should be performed by a qualified small-engine technician. Disable the ignition and disconnect the spark plug before beginning any engine disassembly. Ensure the ring is oriented correctly in the piston groove and that the ring end gap aligns with the locating pin in the groove to prevent rotation and potential cylinder damage.
