About this guide and how we check fitment

This is an independent reference for STIHL chainsaws: engine families, chain and bar fitment, part numbers, parts diagrams and service documents. It is edited by a small independent team. We use an AI assistant for research and drafting. People decide what is published. Each fitment figure either cites the publication it was checked against or carries a confidence label that says how far it has been checked.

How we check fitment

Drive-link counts are checked against STIHL's catalog chart and Oregon's fit chart. Named replacement chain loops are checked against Oregon's product pages for chain type, pitch, gauge and drive-link count. Each model and family page cites the source next to the figure and says when it was last checked.

• STIHL 2025 US catalog, saw chain selection, pp. 166-167, checked Nov 2026.
• Oregon chain fit guide, STIHL section, checked Nov 2026.
• Oregon product pages (chain type, pitch, gauge, drive links), checked Nov 2026.

Other family figures (chain pitch and gauge, recommended bar range, bar mount, displacement and production dates) come from our family research: STIHL product pages and parts catalogues, dealer parts fiche and collector records, last reviewed Jul 2026. These figures carry a confidence label on every page:

• verified: checked against a STIHL publication, product page or the saw itself.
• sourced: taken from a parts catalogue, dealer fiche or collector records, not yet matched to a STIHL publication.
• reconstructed: built from STIHL's model naming and a related model's figures. Plausible, not individually confirmed.
• estimated: our own inference from displacement and class. Lowest confidence; check before you rely on it.

A figure is never upgraded to verified because it looks right. It changes only when we have read the source.

Sources we use

• STIHL catalogs for chain selection and drive-link counts by bar length and mount.
• Oregon's STIHL fit chart and product pages for aftermarket chain families and loop part numbers.
• STIHL parts catalogues and model parts lists (IPLs) for part numbers and exploded views. The main catalogue is a 2012 edition, supplemented by model parts lists from 2019 to 2026; each diagram names its edition.
• STIHL technical information bulletins (1994 to 2011) for part supersessions and changes by serial number.
• STIHL workshop manuals and the 2019 STIHL Technical Reference Guide for service and tuning figures.
• Dealer parts fiche and collector records for production dates, variants and older models that STIHL no longer lists.

When sources disagree or say nothing

If a model is missing from the chart we are checking, or two sources disagree, the page says so rather than filling the gap. The 023 and the MS 340 are examples. Neither appears in the charts we checked for their families, so their rows read "not listed" and tell you to count the drive links on your chain or read the bar stamp, even though a related saw on the same bar mount is listed.

The same rule applies elsewhere. Where a model has no parts diagram in our catalogue, we say so and do not show another model's diagram. A part number shared by two machines means the catalogue listed it on both, not that the parts are interchangeable. Drive-link counts can vary with bar type, so every chain table asks you to confirm the count stamped on your bar.

Corrections

Corrections are the most useful thing a reader can send. We read every report and check it against a source. When a source confirms the error, we fix the underlying data file, rebuild the site and update the checked date, so the figure changes on every page that uses it. Where a correction overturns an earlier source record, the chart panel for that family marks it ⚠.

Report an error or a missing model. It helps to name the saw, the figure that looks wrong and where the correct figure comes from (a STIHL spec sheet, manual, parts list or the stamp on your bar). The form reaches the editors, not STIHL.

Affiliate disclosure

Some links earn us a commission. It never changes the specs or what we recommend. As an Amazon Associate we earn from qualifying purchases. Chain, bar, file, oil and sharpener buttons on model and family pages are Amazon links carrying our Associates tag, marked as sponsored links. A button goes to a single product only when we have checked that the listing matches the fitment; for chain loops that means part number, pitch, gauge and drive-link count. Otherwise it opens an Amazon search narrowed as far as the known fitment allows, such as pitch, gauge, drive-link count or bar mount. We sell nothing ourselves and are not paid by STIHL or Oregon.
