Why Cog Belts Matter
The cog motor belt is a critical component in your Bernina 910's drive system. Unlike smooth V-belts, cog belts have teeth that mesh with toothed pulleys, providing secure engagement and preventing slipping. This ensures reliable power transfer for needle movement, feed dog operation, and all internal components. A worn or damaged cog belt can cause loss of power or complete machine failure.
Bernina 910 Belt System
The Bernina 910 uses two cog belts in its drive system:
- Upper Belt (Part #305.326.03): 170XL031, 85 teeth - this product
- Lower Belt (Part #305.327.03): 240-2GT, 120 teeth - available separately
Consider replacing both belts at the same time if performing major maintenance.
Installation Tips
- Check belt tension after installation - should be snug but not overly tight
- Inspect pulleys for wear or damage when replacing belt
- Ensure teeth properly mesh with pulley grooves
- Consider replacing both upper and lower belts together
- Keep spare belts on hand for future maintenance
