Description
Overview:
The Connecting Rod 4230 640 6800 is a genuine Stihl OEM part for long‐reach hedge trimmers and hedge trimmer attachments, including HL-KM and HL100. Made from high‐quality steel and precision machined, it links the drive mechanism inside the gear head to the cutter assembly, maintaining smooth, efficient reciprocating motion under load. A correct, tight‐tolerance connecting rod helps preserve cutting performance, reduce vibration, and limit premature wear of mating parts. Built to Stihl's specifications, this part restores reliable motion transfer when the original rod has worn, bent, or developed excess play. Suitable for professional and domestic use, it is an essential service item when overhauling the blade drive on compatible Stihl machines, including HL95 models.
Key Features:
- Genuine Stihl OEM part for assured compatibility and performance
- High‐quality steel construction for durability in demanding conditions
- Precision‐machined bores and faces to maintain correct clearances
- Supports smooth, low‐friction motion to minimise heat, wear, and vibration
- Stable under high RPM typical of hedge trimmer gear heads
- Helps restore full cutter stroke and consistent cutting quality
- Fits a wide range of Stihl long‐reach hedge trimmers and Kombi attachments
- Identified by MPN 4230 640 6800 for accurate parts matching
Typical Applications:
Used during service or repair of Stihl hedge trimmer gear heads when symptoms include knocking, blade chatter, reduced stroke, rough running, or excessive play. Common in professional landscaping, estate and grounds maintenance, and domestic hedge care where reliable, smooth blade drive is required for clean cutting.
Also known as:
Con rod, drive link, blade drive rod, crank link, oscillating link, gear head rod, linkage rod, motion transfer rod. These terms refer to the same component that converts rotary drive into the reciprocating movement of the cutter assembly inside the hedge trimmer head.
