Description
4242 641 4900 STIHL Sleeve 4.4 mm – Genuine OEM Gear Head & Cutter Bar Part
The STIHL Sleeve 4.4 mm (4242 641 4900) is a genuine OEM precision spacer component designed to maintain correct alignment and spacing within the gear head and cutter bar assemblies of select STIHL hedge trimmers and long-reach Kombi attachments. This sleeve supports smooth drivetrain operation by reducing excess play and ensuring proper component positioning inside the gearbox and blade drive system.
Over time, sleeves may wear due to vibration, continuous blade movement, debris exposure, or insufficient lubrication. A worn sleeve can lead to misalignment, increased vibration, uneven cutting performance, or accelerated wear on surrounding gear head components. Replacing it with the correct OEM part restores proper assembly tolerances without replacing the complete gearbox or cutter bar system.
Manufactured to STIHL factory specifications, this genuine sleeve ensures exact fitment, durability, and long-term reliability under demanding professional trimming conditions.
