Description
Overview:
This genuine Stihl tension spring (OEM No. 1252 162 7904) is a small but vital component used in the chain tensioning mechanism of Stihl MSA 161 T cordless chainsaws. Made from durable spring steel, it provides the steady force needed to keep the chain correctly tensioned during cutting. Correct tension helps the chain run smoothly on the guide bar, reduces the risk of derailment, and supports safe, efficient operation. Designed specifically for the MSA 161 T (also referred to as MSA161T), this factory part restores original performance when a worn or broken spring is the cause of poor chain retention. It is a like‐for‐like replacement that fits without modification, helping you keep your saw in reliable working order.
Key Features:
- Genuine Stihl part for assured fit and compatibility with MSA 161 T
- Direct replacement for OEM No. 1252 162 7904
- Durable spring steel construction for long service life
- Maintains correct chain tension for smooth, consistent cutting

- Stable, repeatable tension to support accurate, safe operation
Typical Applications:
Used to restore proper chain tensioning on the Stihl MSA 161 T when the existing spring is fatigued, stretched, or broken. Ideal during routine servicing, after chain or bar changes, or when the chain will not hold adjustment. Suits arborists, grounds maintenance teams, landscapers, and DIY users who need reliable chain retention on cordless saws.
