Description
Overview:
The 1/4" (6.35 mm) Chain Sprocket is a genuine Stihl drive component designed specifically for the MSA161T top‐handle chainsaw. Made from high‐quality steel for strength and resistance to wear, it transfers power from the motor to the saw chain, keeping the chain running smoothly and efficiently under load. As an OEM part (No. 1252 642 1202), it matches the original specification for pitch, profile and fit on the MSA161T, so installation is straightforward and alignment is precise. Replacing a worn sprocket helps to reduce chain stretch, vibration and bar wear, restoring consistent cutting performance and protecting related parts. Ideal for routine servicing or like‐for‐like replacement when the existing sprocket shows hooking, rounding, or excessive play.
Key Features:
- Genuine Stihl OEM part for assured compatibility and quality
- 1/4" (6.35 mm) pitch to suit the correct chain specification on the MSA161T
- High‐quality steel construction for durability and reliable engagement
- Direct‐fit replacement; no modifications required on compatible machines
- Supports smooth chain tracking and efficient cutting performance
- Helps limit premature wear on bar and chain when replaced at service intervals
- Precisely machined for accurate alignment and reduced vibration
- Straightforward to fit with basic tools, minimising downtime
Typical Applications:
Used during scheduled maintenance or when symptoms such as chain skipping, noise, or uneven wear appear. Suitable for professional arborists, landscapers, grounds teams, and homeowners using a Stihl MSA161T for pruning, limbing, and general tree care. Replacing the sprocket at the correct intervals helps maintain safe, predictable cutting and prolongs the service life of the bar and chain.
