Several Greenworks manuals list Oregon chain and bar codes, which makes replacements easier once you know the code for your model. This guide lists what Greenworks’ manuals and UK/EU spare-part listings say, and answers the “can I fit a longer bar?” question.
Quick Answer
- Where a Greenworks manual gives a chain code, it is an Oregon 90PX code (3/8″ LP, .043″) — for example on the GD24CS30 and GD24X2CS36. For several models we could not find a Greenworks manual, so check the code in yours.
- The chain code for your exact model is printed in the technical data section of the operator manual; match pitch, gauge and drive-link count.
- Greenworks sells official replacement chains by length (25/35/40 cm SKUs) — but two saws with the same bar length can use different gauges, so always cross-check the manual code before ordering by length alone.
Chain Specs by Model (from Greenworks listings)
Codes below come from Greenworks operator manuals where we found one; other rows show only what Greenworks’ spare-part listings say. Check your manual rather than guessing.
| Model | Range | Bar | Chain (manual code) | Spec | Oregon equivalent |
|---|---|---|---|---|---|
| G40CS30 | 40V | 30 cm (spare bar 29517) | Not confirmed — we found no Greenworks manual for this model | — | — |

Before you buy: check that the size, fitting/bore and maximum-rated speed marked on the accessory match what your tool’s manual specifies. We have not physically tested these products; listings are compiled from published specifications. These are affiliate links.
Bar length alone is not enough: Greenworks does not give the gauge for most of these saws, so read your manual or the bar before ordering.
Greenworks Replacement Part Numbers (UK, from Greenworks listings)
| SKU | Part | Greenworks lists it for |
|---|---|---|
| 29507 | 20 cm chain | Pole saws G24PS20, G40PSH, G40PSF |
| 29587 | 25 cm chain | GD24CS25 |
| 2929107 | 35 cm chain | GD40CS15, GD48CS36, GD24X2CS36 |
| 29767 | 40 cm chain | GD40CS18, GD60CS40, GD40CS40 |
| 29497 / 29517 / 2929007 / 29757 | 20 / 30 / 35 / 40 cm bars | 29497: G24PS20, G40PSH, G40PSF; 29517: G40CS30; 2929007: “G40CS15” as written; 29757: GD40CS40, GD40CS18 |
Greenworks’ shop lists the single 40 cm chain 29767 for the GD40CS18, GD60CS40 and GD40CS40, but gives no pitch, gauge or drive-link count for it. Check the gauge on your bar before ordering.
Can You Fit a Longer Bar on a Greenworks Saw?
The question we see most: “Would a 16″ 3/8″-pitch bar work on my 14″ Greenworks saw?” We have not found any Greenworks approval for it. Greenworks’ manuals list one bar and chain code for each saw (for example Oregon bar 100NDEA041 and chain 91PJ040X for the G24CS25), and other makers’ manuals tell owners to use only replacement bars and chains specified by the manufacturer (WORX, Ryobi). If you need a longer cut, choose a saw sold with that bar length. More on this in can you put a longer bar on a chainsaw?
Finding Your Chain Spec
- Operator manual — technical data section lists the exact chain and bar codes (for example “90PX052X / 144MLEA041” in the GD24X2CS36 manual).
- On the chain — the Oregon family number (90, 91…) is stamped on each drive link.
- Count the drive links — the third number you must match. Our chainsaw chain size chart and measuring guide cover this step by step.

Frequently Asked Questions
Do Oregon chains fit Greenworks chainsaws?
Where a Greenworks manual gives a chain code, it is an Oregon code (for example 90PX045X for the GD24CS30 and 90PX052X for the GD24X2CS36). Match that code, or the pitch, gauge and drive-link count, when you buy. Our Oregon cross-reference chart decodes the numbers.
What chain does a 40V Greenworks 16-inch saw take?
We could not find a Greenworks manual for the 40 cm GD40CS18, so we have not confirmed its chain code. Greenworks lists spare chain 29767 for it (and for the GD60CS40 and GD40CS40) without giving pitch, gauge or drive links.
Can I put a 16-inch bar on my 14-inch Greenworks?
It’s not supported — Greenworks specifies same-size replacement bars and chains only and sells no upsize kits. Stick with the bar and chain codes in your manual.
How We Compile This Guide
Chain and bar codes on this page were read from Greenworks’ official operator manuals and the official Greenworks UK/EU spare-parts listings, cross-checked against Oregon’s published chain specifications. Where a model’s spec could not be verified from an official source, the table says “check manual” rather than borrowing figures from marketplace listings. Last verified August 2026.
Safety disclaimer: Chainsaw bars and chains are safety-critical. Always fit the exact combination specified in your model’s operator manual, keep the chain correctly tensioned, and never fit a chain of a different pitch, gauge or drive-link count. This guide is general information only; use at your own risk.
