Description
Overview:
This Set of Pinions for Stihl FH and HL machines is a Genuine Stihl replacement gear set, supplied under MPN 4230 640 7307. The pinions are precision‐machined steel components that transfer drive within the hedge trimmer gear head, restoring smooth power delivery to the cutter. They are designed for Stihl long‐reach hedge trimmers and attachments, including popular models such as the HL 75 and HL 100. When existing gears are worn, chipped, or noisy, fitting this set helps regain efficient, reliable operation and reduces further wear on related parts. Built for durability and accurate meshing, the set offers a direct fit where specified, making it suitable for routine maintenance or repair by competent users. An essential part for maintaining cutting performance and extending service life.
