Description
Overview:
The Return Spring for ECHO CS-510 and CS-610 chainsaws is a flat spiral spring used in the recoil starter to rewind the pull cord after each pull. This genuine ECHO part is made from durable, tempered spring steel to withstand repeated cycling and maintain consistent tension. It helps the starter handle return smoothly and supports reliable starting performance. Designed as a direct-fit replacement to OEM No. 17723435430, it suits a wide selection of ECHO chainsaws and is suitable for both professional users and DIY owners who need dependable starting in daily use. The compact coil design fits neatly inside the starter housing and restores proper rewind action when an original spring has weakened, kinked, or broken.
Key Features:
- Genuine ECHO part for assured fit and function on compatible models
- Tempered spring steel construction for strength and long service life
- Stable rewind tension helps the pull cord retract cleanly and fully
- Direct replacement for OEM No. 17723435430 to simplify ordering and fitting
- Compact flat-coil design fits the standard recoil housing without modification
- Protective finish to help resist wear during repeated winding cycles
- Supports fast, consistent starting and reduces downtime
- Straightforward to install with basic hand tools
Typical Applications:
Replacement of a worn, stretched, or broken recoil starter spring on ECHO chainsaws used in arborist work, landscaping, forestry, grounds maintenance, and firewood cutting. Ideal for routine service where the starter handle fails to retract fully, the rope rewinds slowly, or the recoil mechanism has lost tension.
