Description
Overview:
This torsion spring is a genuine Stihl OEM component designed to maintain controlled rotational tension in key mechanisms on Stihl cut-off saws, including the TS 410 and TS 420. Made from robust spring steel, the coiled design provides a reliable return or holding force for levers and linkages, helping the machine operate smoothly under dust, vibration, and heavy site use. As a direct replacement for worn or fatigued springs, it restores correct tension where specified in the saw's assembly, supporting consistent performance and safety. Identified under Stihl part number 4238 182 4500, it is suitable for construction and landscaping applications where these disc cutters are commonly used, and is intended for routine maintenance or repair by tradespeople and informed DIY users.
Key Features:
- Genuine Stihl OEM part for assured compatibility and reliability
- Durable spring steel construction for long service life
- Accurate torsional force to maintain correct return/hold tension
- Designed to resist fatigue from repeated cycling and vibration
- Stable leg geometry for secure seating in the housing or lever
- Direct replacement with straightforward fitting when following the model's parts diagram
- Supports consistent operation of control and linkage mechanisms
- Suited to demanding site conditions typical of cut-off saw use
Typical Applications:
Used to replace a weakened or broken torsion spring in control or linkage assemblies on Stihl disc cutters. Typical functions include providing return force for levers or holding components in position as specified by the model's parts diagram. Ideal during routine overhauls, troubleshooting poor return action, or when controls feel slack, helping restore predictable operation on the job.
