Definition
Drive links are the lower tangs that run in the bar groove. Count of drive links is not the same as cutter count.
Bar length alone cannot uniquely determine drive link count because mount geometry and tensioning range differ.
Measurement steps
- Clean the chain and place it flat on a stable surface.
- Mark one drive link as the start point.
- Count each drive tang that would sit in the bar groove.
- Stop when you return to the marked tang and recount once for verification.
- Record drive links with pitch and gauge as a single fitment set.
Common mistakes
- •Counting cutters instead of drive tangs.
- •Estimating drive links from nominal bar length.
- •Mixing up replacement loop labels across similar saw models.
Next step
Use your confirmed parameters in Fitment Finder, then submit an RFQ with pitch, gauge, drive links, and model details.
Compatibility and safe operation depend on OEM documentation, verified measurements, and local safety requirements.
