Compatibility
Engineered to fit Greenworks 20312 saws and other models sharing the same bar-mount pattern. Always double-check your saw’s model number against the full compatibility list before ordering, since mount studs and oiler holes can vary between production years.
Installation notes
Loosen the bar-mount nuts and slide the old assembly off. Before fitting the new bar, clear packed sawdust from the oil passage and around the drive sprocket. Place the new bar onto the studs, route the chain around the bar groove and sprocket, then adjust tension to the point where you can pull the chain around by hand with light resistance. Snug the nuts in a cross pattern.
Common questions
Q: Will this 16 inch bar and chain combo fit my Greenworks 20312, or do I need to match anything besides the bar length?
Yes, this combo is made for the Greenworks 20312 and matches the 16 inch bar length and 3/8 pitch called for by that saw. Before installing, it’s still smart to compare the old bar and chain markings so the drive link setup and mounting pattern match your original parts.
Q: Does this combo come ready to install on a Greenworks 20312, and do I need to sharpen or tension the chain first?
It should install as a complete replacement set, but you will still need to set the chain tension correctly once the bar and chain are mounted. After installation, add bar and chain oil, make sure the chain moves freely by hand with gloves on, and recheck tension after the first few cuts since a new chain can stretch slightly.
Q: Is the 3/8 pitch chain on this 16 inch bar a good match for normal yard work on the Greenworks 20312?
Yes, a 3/8 pitch chain is a standard setup for this size saw and works well for common cutting jobs like trimming limbs and cutting small to medium firewood. Keep the chain sharp and the bar groove clean, because that will do more for cutting performance than the pitch alone.
