Ryobi Chainsaw Chain Sizes (Australia)
Find the Right Chain for Your Ryobi Chainsaw in Two Simple Steps
Choosing the correct chain for your Ryobi chainsaw doesn't have to be difficult. Some Ryobi models are available with different guide bar options, making it important to confirm the exact chain your saw requires.
This guide makes the process simple.
First, learn how to identify the correct chain for your guide bar, then scroll down to the Ryobi Chainsaw Chain Size Chart below to find your model.
Step 1 – Find Your Ryobi Chainsaw Model
Scroll down to the Ryobi Chainsaw Chain Size Chart and locate your Ryobi model together with its guide bar length.
This will show you the recommended replacement chain for your saw.
If your model appears more than once with different gauges or drive link counts, continue to Step 2 to confirm the correct chain.
Step 2 – Check These Two Things on Your Chainsaw
Some Ryobi chainsaws may have replacement guide bars fitted during their lifetime. Checking these two measurements ensures you order the correct replacement chain every time.
1. Drive Links (DL)
The drive link count is the most accurate way to identify your replacement chain.
To calculate it:
- Count the cutters on your existing chain.
- Multiply that number by 2.
- The result is your Drive Link (DL) count.
Example:
22 cutters × 2 = 44 Drive Links (44DL)
If you notice one slightly larger gap between the cutters, your chain has an odd number of drive links, such as 45DL.
2. Gauge
Gauge refers to the thickness of the drive links that fit inside the guide bar groove.
Look for one of these markings stamped on your guide bar near the mounting point:
- .043" (1.1mm)
- .050" (1.3mm)
- .058" (1.5mm)
Your replacement chain must have the exact same gauge as your guide bar.
If the gauge is incorrect, the chain won't fit properly.
Do You Need to Check the Pitch?
Usually, no.
Once you've confirmed the correct Drive Link count and Gauge, the chain pitch will automatically match your Ryobi guide bar.
This makes selecting the correct replacement chain much simpler.
Why This Method Is the Most Accurate
Many Ryobi chainsaws have replacement guide bars fitted over time.
For example, a previous owner may have changed:
- A .043" guide bar to a .050" guide bar
- A .050" guide bar to a .058" guide bar
- A 14-inch bar to a 16-inch bar
- A 16-inch bar to an 18-inch bar
Because of this, relying only on the chainsaw model can sometimes lead to ordering the wrong chain.
Checking your Drive Links and Gauge guarantees the correct fit every time.
