A318 guide bar mount
A318 is the mount code at the end of an Oregon guide-bar number — the tail shape, stud slot and oiler position that decide whether a bar bolts onto your saw. In Oregon's fitment data it covers 19 saw models from 6 brands, in 10" to 18" lengths.
Bars by length
pitch and gauge still have to match your chain| Length | Pitch | Gauge | Oregon bars & combos (A318) |

| 14" | 3/8" LP | .050" | 140SDEA318 |

Source: Oregon part-finder fitment data, retrieved 2026-07-06. The mount is read from the last four characters of each Oregon bar number (e.g. 160SDEA041 → A041).
How to check your bar's mount
- Read the tail of the old bar. Oregon bars print the full part number near the mounting slot; the last four characters are the mount (A318). Other brands print their own number — look it up, or compare the tail by eye.
- Compare slot and holes. Lay the new bar over the old one: the stud slot, the oiler hole and the chain-adjuster hole have to line up.
- Then match the chain. A bar with the right mount still needs a chain of the same pitch, gauge and drive-link count as its groove and nose sprocket.
