Description
Overview:
The Circlips 19 x 1 mm is a genuine Stihl retaining ring for securing components on a shaft in the HL-KM 0-145 angle drive and related hedge trimmer gearheads. Made from durable spring steel, it provides a positive snap-fit into a machined groove, preventing lateral movement and keeping gears, bearings, and spacers correctly located during operation. This small but critical part helps maintain smooth, reliable drive performance under vibration and load. It is suitable for professional and domestic users maintaining Stihl multi-tool attachments and long‐reach hedge trimmers, including the HL-KM 0-145 and FH-KM 145. As an OEM component (9456 621 2000), it offers accurate fitment and long service life when installed to the correct groove size on the intended shaft.
Key Features:
- Genuine Stihl part (OEM 9456 621 2000) for correct fit and function
- 19 x 1 mm circlip for securing parts on a shaft to prevent axial movement
- Spring-steel construction for strength, elasticity, and repeatable retention
- Designed for high-vibration environments typical of angle drive mechanisms
- Helps maintain alignment of gears, bearings, and spacers for smooth running
- Compact profile fits the intended groove without interfering with adjacent parts
