Description
Overview:
The Compression Spring for Stihl (part no. 0000 997 3100) is a genuine OEM replacement used in mowing head assemblies on select Stihl machines. Made from high-grade spring steel, it delivers controlled compression to keep moving parts seated and operating correctly. In the AutoCut 5-2 trimmer head it supports the line-feed mechanism so the spool returns and the bump-feed action works as intended. It is also specified for certain TE-series tools where this spring is part of the original assembly. With an inner diameter of 27.4 mm, an outer diameter of 31 mm, and a free length of 32 mm, it matches factory dimensions for a straightforward swap during servicing or repair. Suitable for both professional users and DIY owners who want reliable, repeatable performance from their equipment.
