Description
Overview:
This non-genuine torsion spring is a direct replacement for OEM part number 1117 182 4500 and is designed for use in a wide range of Stihl petrol chainsaws, including the 028 and MS170. Manufactured from tempered spring steel for strength and resilience, it stores and releases rotational force to maintain the correct tension within key chainsaw control mechanisms. This helps the tool operate smoothly and consistently, reducing the risk of sticking or sluggish controls. The spring is sized for a precise fit in compatible housings and is suitable for routine maintenance or repair when the original spring becomes worn, deformed, or broken. It is a practical choice for tradespeople, arborists, landscapers, and DIY users who need reliable replacement parts for busy, outdoor conditions.
Key Features:
- Non Genuine Part compatible with Stihl models; replaces OEM 1117 182 4500
- Tempered spring steel construction for high fatigue resistance and long service life
- Precision-wound coil for consistent torque and reliable return action
- Helps maintain correct tension in chainsaw mechanisms for smooth operation
- Direct-fit dimensions for fast installation without modification
- Stable performance across typical UK outdoor temperatures and conditions
- Suitable for preventative maintenance and quick repairs to minimise downtime
- Cost-effective replacement to restore function when the original spring is damaged
Typical Applications:
Used during servicing or repairs of compatible Stihl chainsaws to restore proper tension and return action in control mechanisms. Common in forestry, arboriculture, landscaping, grounds maintenance, construction site work, and general firewood processing. Ideal when controls feel weak, slow to return, or fail to engage correctly after heavy use or accidental impact.
Also known as:
Torsion spring, coil spring, twist spring, torsion return spring, control spring, tension return coil. These terms refer to springs that store rotational energy to return levers or linkages to their neutral position in hand-held power tools such as chainsaws.
