Questions people ask
What size chain does a Ryobi RY40510B take?
The Ryobi RY40510B with a 12" bar takes 3/8" LP pitch, .043" gauge chain with 45 drive links (Oregon R45).
What bar fits a Ryobi RY40510B?
A bar with the A041 mount, in one of these lengths: 12".
Can I use a chain with the same length but different pitch?
No. Pitch and gauge have to match the bar and sprocket, and the drive link count has to match the bar. A chain that is off on any of the three will not fit or run safely.
