Efco chainsaw chain and guide bars by model

This guide lists all 35 Efco model names recorded in our Saw Parts Finder, with the common chain and bar configurations from the Oregon 2026 Master Parts Catalog mapping. Use the Parts Finder button above to select your exact model. Always confirm pitch, gauge and drive-link count on the bar fitted to your saw.

Check before ordering: the same model can have different setups. Bar length alone is not enough. Match pitch, gauge, drive links and the bar mount, and confirm the drive sprocket. “Common” and “alternate” follow our finder’s catalog classification, not a guarantee of your factory equipment.

How to confirm your chain

  1. Read the pitch and gauge markings on your current guide bar.
  2. Count the drive links on your old chain; do not count the cutters.
  3. Match the exact configuration in the finder, including bar mount and sprocket requirements.

Bar and part references are fitment information, not a live-stock statement. Use the finder for available store options. Never interchange .043, .050, .058 or .063 gauge chain without the correct matching bar.
