Description
4182 640 0152 STIHL Gear Head – Genuine OEM Part
The STIHL Gear Head (4182 640 0152) is a genuine OEM replacement gear head designed for use on select STIHL gas-powered pole pruners.
This gear head is installed at the cutting end of the drive tube assembly and transfers power from the internal driveshaft to the saw chain, providing the correct gear reduction for smooth, efficient, and controlled cutting performance. Proper gear head operation is critical for maintaining cutting efficiency, driveline reliability, and safe operation during high-reach pruning tasks.
Manufactured to STIHL factory specifications, this OEM gear head ensures precise fitment, durability, and long service life under professional operating conditions.
Replacing a worn, damaged, or noisy gear head helps restore proper power transmission and prevents further damage to internal drivetrain components.
