Description
Overview:
This Thrust Washer is a genuine Stihl spare part for selected cordless hedge trimmers, including the HLA 56 and HSA 56. It is made from wear‐resistant metal and provides a smooth bearing surface to control axial movement in the blade drive and gearbox assemblies. By minimising friction between rotating parts, it supports efficient power transfer, consistent cutting performance, and longer component life. The washer helps maintain correct spacing and alignment, which protects gears, shafts, and bearings from premature wear. It is suitable for routine maintenance and repairs where a worn, scored, or missing washer is causing play, noise, or binding. Genuine Part status ensures the correct fit and tolerance, making it a reliable replacement to restore the trimmer to proper operating condition.
