Description
Overview:
This spool insert is a Genuine Stihl OEM component for AutoCut 36-2, 46-2, and 56-2 trimmer heads used on Stihl FS 36 and FS 46 brushcutters. It is a shaped insert made from durable polymer in a high-visibility orange finish. The insert locates and supports the trimmer line spool within the head so the line feeds evenly and the bump-feed mechanism works as intended. By keeping the spool correctly seated, it helps reduce wear on the head, minimises tangles, and maintains smooth running during grass cutting and light brush work. Supplied under Manufacturer Part Number 40037133001, it restores reliable performance when the original insert has worn or deformed through regular use.
