Description
Overview:
The Chain Sprocket 1/4" Picco 8T is a genuine Stihl replacement part designed for the drive system of Stihl pole pruners, including the HT56C and HT-KM. Made from durable steel, it transfers engine power to the cutting chain for smooth, consistent operation. With a 1/4 inch (6.35 mm) Picco pitch and 8-tooth profile, it matches low-profile 1/4" Picco chains for accurate meshing and efficient cutting performance. This sprocket helps restore proper chain engagement, reduce vibration, and protect the bar and chain from premature wear. Supplied under OEM number 0000 640 2001, it is suitable for routine maintenance or replacing a worn or hooked sprocket to keep your pruner working reliably in regular garden care and professional pruning tasks.
