Maintain the heavy-duty cutting power of your largest professional saws with the STIHL .404" 7-Tooth Rim Sprocket. This genuine replacement part (0000 642 1207) is engineered for STIHL’s "Standard" splined clutch drums, found on high-displacement powerheads designed for the most demanding forestry applications. The floating rim system allows the sprocket to move freely along the splined hub, ensuring the heavy .404" chain stays perfectly aligned with the guide bar groove to minimize friction and maximize power transfer.
The 7-tooth configuration is the industry standard for .404" pitch systems, providing the immense lugging torque required for felling oversized timber and milling large logs. Compatible with legendary powerhouses like the MS 661 and MS 881, this rim sprocket is built from high-strength, hardened steel to withstand the extreme heat and stress of professional logging. Because the rim is a separate wear component, it offers a cost-effective maintenance solution compared to replacing an entire spur sprocket drum.
Professional Power Note: .404" pitch is the "heavy-duty" choice for professional loggers. This sprocket ensures that your drive system can handle the aggressive cutting force of STIHL’s largest chainsaws.
